This change will -produce errors or warnings on incorrect assembly code that previous versions of -gas accepted. If you get unexpected messages from code that worked with older -versions of gas, please double check the code before reporting a bug. - -Weak symbol support added for COFF targets. - -Mitsubishi D30V support added. - -Texas Instruments c80 (tms320c80) support added. - -i960 ELF support added. - -Changes in 2.9: - -Texas Instruments c30 (tms320c30) support added. - -The assembler now optimizes the exception frame information generated by egcs -and gcc 2.8. The new --traditional-format option disables this optimization. - -Added --gstabs option to generate stabs debugging information. - -The -a option takes a new suboption, m (e.g., -alm) to expand macros in a -listing. - -Added -MD option to print dependencies. - -Changes in 2.8: - -BeOS support added. - -MIPS16 support added. - -Motorola ColdFire 5200 support added (configure for m68k and use -m5200). - -Alpha/VMS support added. - -m68k options --base-size-default-16, --base-size-default-32, ---disp-size-default-16, and --disp-size-default-32 added. - -The alignment directives now take an optional third argument, which is the -maximum number of bytes to skip. If doing the alignment would require skipping -more than the given number of bytes, the alignment is not done at all. - -The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. - -The -a option takes a new suboption, c (e.g., -alc), to skip false conditionals -in listings. - -Added new pseudo-op, .equiv; it's like .equ, except that it is an error if the -symbol is already defined. - -Changes in 2.7: - -The PowerPC assembler now allows the use of symbolic register names (r0, etc.) -if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) can be -used any time. PowerPC 860 move to/from SPR instructions have been added. - -Alpha Linux (ELF) support added. - -PowerPC ELF support added. - -m68k Linux (ELF) support added. - -i960 Hx/Jx support added. - -i386/PowerPC gnu-win32 support added. - -SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the -default is to build COFF-only support. To get a set of tools that generate ELF -(they'll understand both COFF and ELF), you must configure with -target=i386-unknown-sco3.2v5elf. - -m88k-motorola-sysv3* support added. - -Changes in 2.6: - -Gas now directly supports macros, without requiring GASP. - -Gas now has an MRI assembler compatibility mode. Use -M or --mri to select MRI -mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the ``.mri -0'' is seen; this can be convenient for inline assembler code. - -Added --defsym SYM=VALUE option. - -Added -mips4 support to MIPS assembler. - -Added PIC support to Solaris and SPARC SunOS 4 assembler. - -Changes in 2.4: - -Converted this directory to use an autoconf-generated configure script. - -ARM support, from Richard Earnshaw. - -Updated VMS support, from Pat Rankin, including considerably improved debugging -support. - -Support for the control registers in the 68060. - -Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to -provide for possible future gcc changes, for targets where gas provides some -features not available in the native assembler. If the native assembler is -used, it should become obvious pretty quickly what the problem is. - -Usage message is available with "--help". - -The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 -also, but didn't get into the NEWS file.) - -Weak symbol support for a.out. - -A bug in the listing code which could cause an infinite loop has been fixed. -Bugs in listings when generating a COFF object file have also been fixed. - -Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by Paul -Kranenburg. - -Improved Alpha support. Immediate constants can have a much larger range now. -Support for the 21164 has been contributed by Digital. - -Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. - -Changes in 2.3: - -Mach i386 support, by David Mackenzie and Ken Raeburn. - -RS/6000 and PowerPC support by Ian Taylor. - -VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, -based on mail received from various people. The `-h#' option should work again -too. - -HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work -with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special -version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve -this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu -in the "dist" directory. - -Vax support in gas fixed for BSD, so it builds and seems to run a couple simple -tests okay. I haven't put it through extensive testing. (GNU make is -currently required for BSD 4.3 builds.) - -Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is -based on code donated by CMU, which used an a.out-based format. I'm afraid the -alpha-a.out support is pretty badly mangled, and much of it removed; making it -work will require rewriting it as BFD support for the format anyways. - -Irix 5 support. - -The test suites have been fixed up a bit, so that they should work with a -couple different versions of expect and dejagnu. - -Symbols' values are now handled internally as expressions, permitting more -flexibility in evaluating them in some cases. Some details of relocation -handling have also changed, and simple constant pool management has been added, -to make the Alpha port easier. - -New option "--statistics" for printing out program run times. This is intended -to be used with the gcc "-Q" option, which prints out times spent in various -phases of compilation. (You should be able to get all of them printed out with -"gcc -Q -Wa,--statistics", I think.) - ----------------------------------------------------------------- - -Changes in 2.2: - -RS/6000 AIX and MIPS SGI Irix 5 support has been added. - -Configurations that are still in development (and therefore are convenient to -have listed in configure.in) still get rejected without a minor change to -gas/Makefile.in, so people not doing development work shouldn't get the -impression that support for such configurations is actually believed to be -reliable. - -The program name (usually "as") is printed when a fatal error message is -displayed. This should prevent some confusion about the source of occasional -messages about "internal errors". - -ELF support is falling into place. Support for the 386 should be working. -Support for SPARC Solaris is in. HPPA support from Utah is being integrated. - -Symbol values are maintained as expressions instead of being immediately boiled -down to add-symbol, sub-symbol, and constant. This permits slightly more -complex calculations involving symbols whose values are not alreadey known. - -DBX-style debugging info ("stabs") is now supported for COFF formats. -If any stabs directives are seen in the source, GAS will create two new -sections: a ".stab" and a ".stabstr" section. The format of the .stab -section is nearly identical to the a.out symbol format, and .stabstr is -its string table. For this to be useful, you must have configured GCC -to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB -that can use the stab sections (4.11 or later). - -LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS -support is in progress. - ----------------------------------------------------------------- - -Changes in 2.1: - -Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been -incorporated, but not well tested yet. - -Altered the opcode table split for m68k; it should require less VM to compile -with gcc now. - -Some minor adjustments to add (Convergent Technologies') Miniframe support, -suggested by Ronald Cole. - -HPPA support (running OSF only, not HPUX) has been contributed by Utah. This -includes improved ELF support, which I've started adapting for SPARC Solaris -2.x. Integration isn't completely, so it probably won't work. - -HP9000/300 support, donated by HP, has been merged in. - -Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. - -Better error messages for unsupported configurations (e.g., hppa-hpux). - -Test suite framework is starting to become reasonable. - ----------------------------------------------------------------- - -Changes in 2.0: - -Mostly bug fixes. - -Some more merging of BFD and ELF code, but ELF still doesn't work. - ----------------------------------------------------------------- - -Changes in 1.94: - -BFD merge is partly done. Adventurous souls may try giving configure the -"--with-bfd-assembler" option. Currently, ELF format requires it, a.out format -accepts it; SPARC CPU accepts it. It's the default only for OS "elf" or -"solaris". (ELF isn't really supported yet. It needs work. I've got some -code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not fully -merged yet.) - -The 68K opcode table has been split in half. It should now compile under gcc -without consuming ridiculous amounts of memory. - -A couple data structures have been reduced in size. This should result in -saving a little bit of space at runtime. - -Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF -code provided ROSE format support, which I haven't merged in yet. (I can make -it available, if anyone wants to try it out.) Ralph's code, for BSD 4.4, -supports a.out format. We don't have ECOFF support in just yet; it's coming. - -Support for the Hitachi H8/500 has been added. - -VMS host and target support should be working now, thanks chiefly to Eric -Youngdale. - ----------------------------------------------------------------- - -Changes in 1.93.01: - -For m68k, support for more processors has been added: 68040, CPU32, 68851. - -For i386, .align is now power-of-two; was number-of-bytes. - -For m68k, "%" is now accepted before register names. For COFF format, which -doesn't use underscore prefixes for C labels, it is required, so variable "a0" -can be distinguished from the register. - -Last public release was 1.38. Lots of configuration changes since then, lots -of new CPUs and formats, lots of bugs fixed. - - -Local variables: -fill-column: 79 -End: |
