NEWLIB is most often used in cross +environments. + +NOTE THAT YOU MUST HAVE ALREADY BUILT AND INSTALLED GCC and BINUTILS. + + +More Documentation +================== + + Newlib documentation is available on the net via: + http://www.cygnus.com/pubs/gnupro + + All the documentation for NEWLIB comes as part of the machine-readable +distribution. The documentation is written in Texinfo format, which is +a documentation system that uses a single source file to produce both +on-line information and a printed manual. You can use one of the Info +formatting commands to create the on-line version of the documentation +and TeX (or `texi2roff') to typeset the printed version. + + If you want to format these Info files yourself, you need one of the +Info formatting programs, such as `texinfo-format-buffer' or `makeinfo'. + + If you want to typeset and print copies of this manual, you need TeX, +a program to print its DVI output files, and `texinfo.tex', the Texinfo +definitions file. + + TeX is a typesetting program; it does not print files directly, but +produces output files called DVI files. To print a typeset document, +you need a program to print DVI files. If your system has TeX +installed, chances are it has such a program. The precise command to +use depends on your system; `lpr -d' is common; another (for PostScript +devices) is `dvips'. The DVI print command may require a file name +without any extension or a `.dvi' extension. + + TeX also requires a macro definitions file called `texinfo.tex'. +This file tells TeX how to typeset a document written in Texinfo +format. On its own, TeX cannot read, much less typeset a Texinfo file. +`texinfo.tex' is distributed with NEWLIB and is located in the +`newlib-VERSION-NUMBER/texinfo' directory. + + + +Compiling NEWLIB in another directory +===================================== + + If you want to run NEWLIB versions for several host or target machines, +you need a different `newlib' compiled for each combination of host and +target. `configure' is designed to make this easy by allowing you to +generate each configuration in a separate subdirectory, rather than in +the source directory. If your `make' program handles the `VPATH' +feature correctly (like GNU `make') running `make' in each of these +directories builds the `newlib' libraries specified there. + + To build `newlib' in a separate directory, run `configure' with the +`--srcdir' option to specify where to find the source. (You also need +to specify a path to find `configure' itself from your working +directory. If the path to `configure' would be the same as the +argument to `--srcdir', you can leave out the `--srcdir' option; it +will be assumed.) + + For example, with version 1.8.2, you can build NEWLIB in a separate +directory for a Sun 4 cross m68k-aout environment like this: + + cd newlib-1.8.2 + mkdir ../newlib-m68k-aout + cd ../newlib-m68k-aout + ../newlib-1.8.2/configure --host=sun4 --target=m68k-aout + make + + When `configure' builds a configuration using a remote source +directory, it creates a tree for the binaries with the same structure +(and using the same names) as the tree under the source directory. In +the example, you'd find the Sun 4 library `libiberty.a' in the +directory `newlib-m68k-aout/libiberty', and NEWLIB itself in +`newlib-m68k-aout/newlib'. + + When you run `make' to build a program or library, you must run it +in a configured directory--whatever directory you were in when you +called `configure' (or one of its subdirectories). + + The `Makefile' that `configure' generates in each source directory +also runs recursively. If you type `make' in a source directory such +as `newlib-1.8.2' (or in a separate configured directory configured with +`--srcdir=PATH/newlib-1.8.2'), you will build all the required libraries. + + When you have multiple hosts or targets configured in separate +directories, you can run `make' on them in parallel (for example, if +they are NFS-mounted on each of the hosts); they will not interfere +with each other. + + +Specifying names for hosts and targets +====================================== + + The specifications used for hosts and targets in the `configure' +script are based on a three-part naming scheme, but some short +predefined aliases are also supported. The full naming scheme encodes +three pieces of information in the following pattern: + + ARCHITECTURE-VENDOR-OS + + For example, you can use the alias `sun4' as a HOST argument or in a +`--target=TARGET' option. The equivalent full name is +`sparc-sun-sunos4'. + + The `configure' script accompanying NEWLIB does not provide any query +facility to list all supported host and target names or aliases. +`configure' calls the Bourne shell script `config.sub' to map +abbreviations to full names; you can read the script, if you wish, or +you can use it to test your guesses on abbreviations--for example: + + % sh config.sub sun4 + sparc-sun-sunos4.1.1 + % sh config.sub sun3 + m68k-sun-sunos4.1.1 + % sh config.sub decstation + mips-dec-ultrix4.2 + % sh config.sub hp300bsd + m68k-hp-bsd + % sh config.sub i386v + i386-pc-sysv + % sh config.sub i786v + Invalid configuration `i786v': machine `i786v' not recognized + + +`configure' options +=================== + + Here is a summary of the `configure' options and arguments that are +most often useful for building NEWLIB. `configure' also has several other +options not listed here. + + configure [--help] + [--prefix=DIR] + [--srcdir=PATH] + [--target=TARGET] HOST + +You may introduce options with a single `-' rather than `--' if you +prefer; but you may abbreviate option names if you use `--'. + +`--help' + Display a quick summary of how to invoke `configure'. + +`--prefix=DIR' + Configure the source to install programs and files in directory + `DIR'. + +`--exec-prefix=DIR' + Configure the source to install host-dependent files in directory + `DIR'. + +`--srcdir=PATH' + *Warning: using this option requires GNU `make', or another `make' + that compatibly implements the `VPATH' feature. + Use this option to make configurations in directories separate + from the NEWLIB source directories. Among other things, you can use + this to build (or maintain) several configurations simultaneously, + in separate directories. `configure' writes configuration + specific files in the current directory, but arranges for them to + use the source in the directory PATH. `configure' will create + directories under the working directory in parallel to the source + directories below PATH. + +`--norecursion' + Configure only the directory level where `configure' is executed; + do not propagate configuration to subdirectories. + +`--target=TARGET' + Configure NEWLIB for running on the specified TARGET. + + There is no convenient way to generate a list of all available + targets. + +`HOST ...' + Configure NEWLIB to be built using a cross compiler running on + the specified HOST. + + There is no convenient way to generate a list of all available + hosts. + + +Reporting Bugs +============== + +The correct address for reporting bugs found in NEWLIB is +"newlib@sourceware.cygnus.com".

You can also use <> for this purpose by +calling it with <<0>> as the <[nbytes]> argument. + +The <> function returns a block of size <[nbytes]> aligned +to a <[align]> boundary.

This + seems to suffice for all current machines and C compilers. + + Assumed pointer representation: 4 or 8 bytes + Code for 8-byte pointers is untested by me but has worked + reliably by Wolfram Gloger, who contributed most of the + changes supporting this. + + Assumed size_t representation: 4 or 8 bytes + Note that size_t is allowed to be 4 bytes even if pointers are 8. + + Minimum overhead per allocated chunk: 4 or 8 bytes + Each malloced chunk has a hidden overhead of 4 bytes holding size + and status information. + + Minimum allocated size: 4-byte ptrs: 16 bytes (including 4 overhead) + 8-byte ptrs: 24/32 bytes (including, 4/8 overhead) + + When a chunk is freed, 12 (for 4byte ptrs) or 20 (for 8 byte + ptrs but 4 byte size) or 24 (for 8/8) additional bytes are + needed; 4 (8) for a trailing size field + and 8 (16) bytes for free list pointers. Thus, the minimum + allocatable size is 16/24/32 bytes. + + Even a request for zero bytes (i.e., malloc(0)) returns a + pointer to something of the minimum allocatable size. + + Maximum allocated size: 4-byte size_t: 2^31 - 8 bytes + 8-byte size_t: 2^63 - 16 bytes + + It is assumed that (possibly signed) size_t bit values suffice to + represent chunk sizes. `Possibly signed' is due to the fact + that `size_t' may be defined on a system as either a signed or + an unsigned type. To be conservative, values that would appear + as negative numbers are avoided. + Requests for sizes with a negative sign bit will return a + minimum-sized chunk. + + Maximum overhead wastage per allocated chunk: normally 15 bytes + + Alignnment demands, plus the minimum allocatable size restriction + make the normal worst-case wastage 15 bytes (i.e., up to 15 + more bytes will be allocated than were requested in malloc), with + two exceptions: + 1. Because requests for zero bytes allocate non-zero space, + the worst case wastage for a request of zero bytes is 24 bytes. + 2. For requests >= mmap_threshold that are serviced via + mmap(), the worst case wastage is 8 bytes plus the remainder + from a system page (the minimal mmap unit); typically 4096 bytes. + +* Limitations + + Here are some features that are NOT currently supported + + * No user-definable hooks for callbacks and the like. + * No automated mechanism for fully checking that all accesses + to malloced memory stay within their bounds. + * No support for compaction. + +* Synopsis of compile-time options: + + People have reported using previous versions of this malloc on all + versions of Unix, sometimes by tweaking some of the defines + below. It has been tested most extensively on Solaris and + Linux. It is also reported to work on WIN32 platforms. + People have also reported adapting this malloc for use in + stand-alone embedded systems. + + The implementation is in straight, hand-tuned ANSI C. Among other + consequences, it uses a lot of macros. Because of this, to be at + all usable, this code should be compiled using an optimizing compiler + (for example gcc -O2) that can simplify expressions and control + paths. + + __STD_C (default: derived from C compiler defines) + Nonzero if using ANSI-standard C compiler, a C++ compiler, or + a C compiler sufficiently close to ANSI to get away with it. + DEBUG (default: NOT defined) + Define to enable debugging. Adds fairly extensive assertion-based + checking to help track down memory errors, but noticeably slows down + execution. + SEPARATE_OBJECTS (default: NOT defined) + Define this to compile into separate .o files. You must then + compile malloc.c several times, defining a DEFINE_* macro each + time. The list of DEFINE_* macros appears below. + MALLOC_LOCK (default: NOT defined) + MALLOC_UNLOCK (default: NOT defined) + Define these to C expressions which are run to lock and unlock + the malloc data structures. Calls may be nested; that is, + MALLOC_LOCK may be called more than once before the corresponding + MALLOC_UNLOCK calls. MALLOC_LOCK must avoid waiting for a lock + that it already holds. + MALLOC_ALIGNMENT (default: NOT defined) + Define this to 16 if you need 16 byte alignment instead of 8 byte alignment + which is the normal default. + SIZE_T_SMALLER_THAN_LONG (default: NOT defined) + Define this when the platform you are compiling has sizeof(long) > sizeof(size_t). + The option causes some extra code to be generated to handle operations + that use size_t operands and have long results. + REALLOC_ZERO_BYTES_FREES (default: NOT defined) + Define this if you think that realloc(p, 0) should be equivalent + to free(p). Otherwise, since malloc returns a unique pointer for + malloc(0), so does realloc(p, 0). + HAVE_MEMCPY (default: defined) + Define if you are not otherwise using ANSI STD C, but still + have memcpy and memset in your C library and want to use them. + Otherwise, simple internal versions are supplied. + USE_MEMCPY (default: 1 if HAVE_MEMCPY is defined, 0 otherwise) + Define as 1 if you want the C library versions of memset and + memcpy called in realloc and calloc (otherwise macro versions are used). + At least on some platforms, the simple macro versions usually + outperform libc versions. + HAVE_MMAP (default: defined as 1) + Define to non-zero to optionally make malloc() use mmap() to + allocate very large blocks. + HAVE_MREMAP (default: defined as 0 unless Linux libc set) + Define to non-zero to optionally make realloc() use mremap() to + reallocate very large blocks. + malloc_getpagesize (default: derived from system #includes) + Either a constant or routine call returning the system page size. + HAVE_USR_INCLUDE_MALLOC_H (default: NOT defined) + Optionally define if you are on a system with a /usr/include/malloc.h + that declares struct mallinfo. It is not at all necessary to + define this even if you do, but will ensure consistency. + INTERNAL_SIZE_T (default: size_t) + Define to a 32-bit type (probably `unsigned int') if you are on a + 64-bit machine, yet do not want or need to allow malloc requests of + greater than 2^31 to be handled. This saves space, especially for + very small chunks. + INTERNAL_LINUX_C_LIB (default: NOT defined) + Defined only when compiled as part of Linux libc. + Also note that there is some odd internal name-mangling via defines + (for example, internally, `malloc' is named `mALLOc') needed + when compiling in this case. These look funny but don't otherwise + affect anything. + INTERNAL_NEWLIB (default: NOT defined) + Defined only when compiled as part of the Cygnus newlib + distribution. + WIN32 (default: undefined) + Define this on MS win (95, nt) platforms to compile in sbrk emulation. + LACKS_UNISTD_H (default: undefined) + Define this if your system does not have a . + MORECORE (default: sbrk) + The name of the routine to call to obtain more memory from the system. + MORECORE_FAILURE (default: -1) + The value returned upon failure of MORECORE. + MORECORE_CLEARS (default 1) + True (1) if the routine mapped to MORECORE zeroes out memory (which + holds for sbrk). + DEFAULT_TRIM_THRESHOLD + DEFAULT_TOP_PAD + DEFAULT_MMAP_THRESHOLD + DEFAULT_MMAP_MAX + Default values of tunable parameters (described in detail below) + controlling interaction with host system routines (sbrk, mmap, etc). + These values may also be changed dynamically via mallopt().

"Nextchunk" is the beginning of the next contiguous chunk. + + Chunks always begin on even word boundries, so the mem portion + (which is returned to the user) is also on an even word boundary, and + thus double-word aligned. + + Free chunks are stored in circular doubly-linked lists, and look like this: + + chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Size of previous chunk | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + `head:' | Size of chunk, in bytes |P| + mem-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Forward pointer to next chunk in list | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Back pointer to previous chunk in list | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + | Unused space (may be 0 bytes long) . + . . + . | +nextchunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + `foot:' | Size of chunk, in bytes | + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + + The P (PREV_INUSE) bit, stored in the unused low-order bit of the + chunk size (which is always a multiple of two words), is an in-use + bit for the *previous* chunk. If that bit is *clear*, then the + word before the current chunk size contains the previous chunk + size, and can be used to find the front of the previous chunk. + (The very first chunk allocated always has this bit set, + preventing access to non-existent (or non-owned) memory.) + + Note that the `foot' of the current chunk is actually represented + as the prev_size of the NEXT chunk. (This makes it easier to + deal with alignments etc). + + The two exceptions to all this are + + 1. The special chunk `top', which doesn't bother using the + trailing size field since there is no + next contiguous chunk that would have to index off it. (After + initialization, `top' is forced to always exist. If it would + become less than MINSIZE bytes long, it is replenished via + malloc_extend_top.) + + 2. Chunks allocated via mmap, which have the second-lowest-order + bit (IS_MMAPPED) set in their size fields. Because they are + never merged or traversed from any other chunk, they have no + foot size or inuse information. + + Available chunks are kept in any of several places (all declared below): + + * `av': An array of chunks serving as bin headers for consolidated + chunks. Each bin is doubly linked. The bins are approximately + proportionally (log) spaced. There are a lot of these bins + (128). This may look excessive, but works very well in + practice. All procedures maintain the invariant that no + consolidated chunk physically borders another one. Chunks in + bins are kept in size order, with ties going to the + approximately least recently used chunk. + + The chunks in each bin are maintained in decreasing sorted order by + size. This is irrelevant for the small bins, which all contain + the same-sized chunks, but facilitates best-fit allocation for + larger chunks. (These lists are just sequential. Keeping them in + order almost never requires enough traversal to warrant using + fancier ordered data structures.) Chunks of the same size are + linked with the most recently freed at the front, and allocations + are taken from the back. This results in LRU or FIFO allocation + order, which tends to give each chunk an equal opportunity to be + consolidated with adjacent freed chunks, resulting in larger free + chunks and less fragmentation. + + * `top': The top-most available chunk (i.e., the one bordering the + end of available memory) is treated specially. It is never + included in any bin, is used only if no other chunk is + available, and is released back to the system if it is very + large (see M_TRIM_THRESHOLD). + + * `last_remainder': A bin holding only the remainder of the + most recently split (non-top) chunk. This bin is checked + before other non-fitting chunks, so as to provide better + locality for runs of sequentially allocated chunks. + + * Implicitly, through the host system's memory mapping tables. + If supported, requests greater than a threshold are usually + serviced via calls to mmap, and then later released via munmap. + +*/ + + + + + + +/* sizes, alignments */ + +#define SIZE_SZ (sizeof(INTERNAL_SIZE_T)) +#ifndef MALLOC_ALIGNMENT +#define MALLOC_ALIGN 8 +#define MALLOC_ALIGNMENT (SIZE_SZ + SIZE_SZ) +#else +#define MALLOC_ALIGN MALLOC_ALIGNMENT +#endif +#define MALLOC_ALIGN_MASK (MALLOC_ALIGNMENT - 1) +#define MINSIZE (sizeof(struct malloc_chunk)) + +/* conversion from malloc headers to user pointers, and back */ + +#define chunk2mem(p) ((Void_t*)((char*)(p) + 2*SIZE_SZ)) +#define mem2chunk(mem) ((mchunkptr)((char*)(mem) - 2*SIZE_SZ)) + +/* pad request bytes into a usable size */ + +#define request2size(req) \ + (((long)((req) + (SIZE_SZ + MALLOC_ALIGN_MASK)) < \ + (long)(MINSIZE + MALLOC_ALIGN_MASK)) ?

If the input is the empty string, a wchar_t nul +is placed in the output string and 0 is returned. If the input +has a length of 0, no changes are made to the <> output string. + +PORTABILITY +<> is required in the ANSI C standard.

+; +; NOTE: The 29027 is the floating point coprocessor for the 29000. +; It contains 8 floating point registers FP0 to FP7. Three of +; these, FP0, FP1, and FP2, are currently designated as scratch, +; that is, they will not be preserved across calls. The other +; five contain values that must be saved whenever they are used +; in code, and restored before the exit of the routine. The 29027 +; registers are tagged with a single bit indicating the precision +; of the current value. When numbers are read into the 29027, +; they are always stored in double precision, so that single +; precision values are converted on input. Only the MOVE instruction +; fails to do this automatic widening. If the result from calculations +; in the 29027 ALU (determined by the result precision bit in the +; instruction word) is to be single precision and the result saved in +; an FP reg, the result precision bit from the instruction gets copied +; into the precision bit for the register. If a single precision +; SNaN is saved from the 29027, it will be converted to a double +; precision QNaN. Along the way it will cause an unmasked exception +; when read off the chip and cause changes to the status register. +; So the preservation routine will need to modify the mode register to +; mask off the exceptions, save the state of the status register before +; saving the FP regs, and restore the status and mode registers to their +; original settings when the save is complete. +; +; REFERENCE: The instructions to drive the Am29027 are described in the +; Am29027 manual beginning on page 17.

These macros will be after the entry code for a transcendental +; routine. This entry code will move the original function arguments +; (by value, if the target language is FORTRAN) into the global +; registers t0/t1 and t2/t3 (t0 and t2 for single precision +; routines). +; 2. The sources of all operands will be one register from the +; following list: +; t0 or t2 - the source is one of the original input operands +; rtn0 - the source is rtn0, which should be used as the +; source for all constant values to be sent to the +; AM29027 (when used) +; FP0 - FP7 - the source is one of the fp registers +; 3. The destination of all operations will be a register from the +; following list: +; rtn0 - the destination is the function return value +; FP0 - FP7 - the destination is one of the fp registers +; 4. The additional registers available for temporary use are +; t4, lrp, and slp. +; +; These register definitions are all taken from the file "proregs.a" +; which was supplied by AMD. NOTE that the FP0-FP7 registers, for the +; Am29000 version of the file, overlap with the rtn0-rtn15 registers, so +; that FP0 corresponds to rtn0/rtn1, FP1 to rtn2/rtn3, and so forth. +; + .equ ERROR,0 + .equ NO_ERROR,1 + + .equ DOUBLE_FUNCTION,0 + .equ SINGLE_FUNCTION,1 + + .equ T_OPERATION,0 + .equ Q_OPERATION,1 + + .equ R_SOURCE_29000,0 + .equ R_SOURCE_29027,1 + + .equ S_SOURCE_29000,0 + .equ S_SOURCE_29027,1 + + .equ DESTINATION_29000, 0 + .equ DESTINATION_29027, 1 + +;
