* Fix VMS implicit rules and UNIX paths.John Malmberg2014-10-201-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes VMS implicit rules and UNIX style pathname handling. It also fixes some of the VMS style pathname handling, more work there will be needed later. TODO: There are other case insensitive platforms besides VMS. We need to find out why there is extra VMS code for this. This indicates either the extra VMS code is not needed, or the case insensitive support may not be complete on the other case insensitive platforms. * default.c: Add missing definitions to default_suffix_rules[] and default_variables[]. TODO: As it is important that VMS DCL mode definitions must always be a superset of UNIX definitions, a better way of maintaining the VMS DCL mode definitions should be devised. * dir.c (downcase_inplace): Add a reentrant downcase() routine. Add future support for VMS 8.2+ _USE_STD_STAT macro which will disable a lot of VMS specific code from compiling. (dir_file_exists_p): vmsify filename only if directory name has VMS directory delimiters. (file_exists_p): Handle both VMS and UNIX directories. (file_impossible): Handle both VMS and Unix directories. Track whether a VMS format path is needed for the return value. * file.c (lookup_file): Check if vmsify is needed; handle UNIX paths. * implicit.c (pattern_search): Enable UNIX paths. * read.c (parse_file_seq): Enable UNIX paths. * remake.c (f_mtime): Fix gpath_search call for VMS paths. * rule.c (count_implicit_rule): Enable UNIX paths, Fix VMS paths. * vpath.c (selective_vpath_search): Enable UNIX paths.

* [Bug #39310] Parse simple pattern prereqs for globbing.Paul Smith2013-07-221-11/+12
| | | | | | | We tried to get some efficiency by avoiding a parse_file_seq() for simple pattern prerequisites, but this also means no wildcard expansion was happening, so add it back. Add regression tests for wildcards in target and prerequisite lists.
* Keep a local count of the max dependency list size.Paul Smith2013-07-091-6/+8
| | | | | This global variable could be modified during recursion so keep our own local copy to compare against.
* Create a character map to use for locating stop-points in strings.Paul Smith2013-06-221-1/+1
| | | | | | | | | In various places we were passing flags and characters to compare, then using complex conditionals to see where to stop in string searches. Performance numbers reveal that we were spending as much as 23% of our processing time in these functions, most of it in the comparison lines. Instead create a character map and use a single bitwise comparison to determine if this is any one of the stop characters.

| | | | | | | | | | | | | | | string into the strcache. As a side-effect, many more structure members and function arguments can/should be declared const. As mentioned in the changelog, unfortunately measurement shows that this change does not yet reduce memory. The problem is with secondary expansion: because of this we store all the prerequisites in the string cache twice. First we store the prerequisite string after initial expansion but before secondary expansion, then we store each individual file after secondary expansion and expand_deps(). I plan to change expand_deps() to be callable in either context (eval or snap_deps) then have non-second-expansion targets call expand_deps() during eval, so that we only need to store that dependency list once.
* Another round of cleanups:Paul Smith2006-04-091-64/+62
| | | | | | | | - Add more warnings. - Rename variables that mask out-scope vars with the same name. - Remove all casts of return values from xmalloc, xrealloc, and alloca. - Remove casts of the first argument to xrealloc. - Convert all bcopy/bzero/bcmp invocations to use memcp/memmove/memset/memcmp.

* Release GNU make 3.81.Paul Smith2006-04-011-3/+2
| | | | | | | | | Update NEWS docs. Enhance the manual to use automake version.texi, and use the canonical FSF copyright features and statement. Some $(realpath ...) tests won't work on Windows; leave them out The jobserver filedescriptor test might fail if some FDs are reserved, so for now comment out that check.

* Make second expansion optional (partial implementation).Paul Smith2005-10-241-9/+5
| | | | | | | | | | | | | | | | I decided this feature was too impacting to make the permanent default behavior. This set of changes makes the default behavior of make the old behavior (no second expansion). If you want second expansion, you must define the .SECONDEXPANSION: special target before the first target that needs it. This set of changes ONLY fixes explicit and static pattern rules to work like this. Implicit rules still have second expansion enabled all the time: I'll work on that next. Note that there is still a backward-incompatibility: now to get the old SysV behavior using $$@ etc. in the prerequisites list you need to set .SECONDEXPANSION: as well.

* Fix performance degradation introduced by the second expansion feature.Paul Smith2005-04-131-11/+13
| | | | | | | | | | | | | | | | | | I did this by adding intelligence into the algorithm such that the second expansion was only actually performed when the prerequisite list contained at least one "$", so we knew it is actually needed. Without this we were using up a LOT more memory, since every single target (even ones never used by make) had their file variables initialized. This also used a lot more CPU, since we needed to create and populate a new variable hash table for every target. There is one issue remaining with this feature: it leaks memory. In pattern_search() we now initialize the file variables for every pattern target, which allocates a hash table, etc. However, sometimes we recursively invoke pattern_search() (for intermediate files) with an automatic variable (alloca() I believe) as the file. When that function returns, obviously, the file variable hash memory is lost.
