2009-10-06Fix savannah bug 25780. Optimize things a bit.Boris Kolpackov1-1/+0
2009-09-30Fix Savannah bugs #15110, #25493, #12686, and #17740.Boris Kolpackov1-0/+1
2009-09-27- Add static pattern targets to the string cache.Paul Smith1-1/+2
- Use specific free_*() calls where appropriate.
2009-09-24- Rework secondary expansion so we only defer it if there's a possibilityPaul Smith1-3/+6
it might be needed: for most situations we parse prereqs immediately as we used to. Reduces memory usage. - Fixes Savannah bug #18622.
2009-09-16- Add xcalloc() and call itPaul Smith1-5/+13
- Fix memory errors found by valgrind - Remove multi_glob() and empower parse_file_seq() to do its job: the goal here is to remove the confusing reverse/re-reverse we do on the file lists: needed for future fixes. - Add a prefix arg to parse_file_seq() - Make concat() variadic so it can take arbitrary #'s of strings

2007-03-20This is a major update, which switches virtually every allocated-but-not-freedPaul Smith1-10/+5
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.
2006-11-18Fix from Eli for incorrect value of $(MAKE) on Cygwin.Paul Smith1-1/+1
A few changes from char* to void* where appropriate, and removing of unnecessary casts. Much more work on const-ifying the codebase. This round involves some code changes to make it correct. NOTE!! There will almost certainly be problems on the non-POSIX ports that will need to be addressed after the const changes are finished: they will need to be const-ified properly and there may need to be some changes to allocate memory, etc. as well. The next (last?) big push for this, still to come, is const-ifying the filenames in struct file, struct dep, etc. This will allow us to store file names in the string cache and finally resolve Savannah bug #15182 (make uses too much memory), among other advantages.

2006-02-11Last of the copyright updates.Paul Smith1-1/+2
2006-02-11Update copyright and license notices on all files.Paul Smith1-13/+11
Added new file strcache.c to various non-UNIX makefiles and build scripts.
2005-10-24Make second expansion optional (partial implementation).Paul Smith1-1/+3
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.
2005-04-13Fix performance degradation introduced by the second expansion feature.Paul Smith1-0/+1
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.

2004-05-16Various enhancementsPaul Smith1-1/+1
- OS/2 Patches - OpenVMS updates - Sanitize the handling of -include/sinclude with and without -k - Fix the setting of $< for order-only rules.
2002-07-08Various cleanups reported by people using the alpha release.Paul Smith1-1/+2
Incorporate "order-only" prerequisites patch. Wrote a test for it. The test shows what might be a bug in the code; I need to look at it more closely (anyway it doesn't behave as I expected). Also I haven't done the docs yet.
2002-07-08Major updates in preparation for 3.80.Paul Smith1-0/+1
New version of the manual, put into the doc subdir. Enhancements: $(eval ...) and $(value ...) functions, various bug fixes, etc. See the ChangeLog. More to come.
1999-07-15* Fix up and document $(apply ...) function.Paul Smith1-2/+1
1999-07-09* Fixed error rebuilding makefiles with -j>1Paul Smith1-1/+2
* Fixed problem with job pipe and -j>1 when waiting on -l loads.
1999-03-05* Update FSF address info in copyright notices.Paul Smith1-1/+2
* Update maintainers build process; remove GNUmakefile. Require builders to run automake && autoreconf by hand. * Use AC_SUBST_FILE to get the maintMakefile included, rather than GNU make's include directive, which conflicts with automake 1.4's include directive.
