2005-04-13Fix performance degradation introduced by the second expansion feature.Paul Smith1-11/+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.

rules, static pattern rules and implicit rules.
2004-09-21Fixed bug in implicit rule prerequisite evaluation code. Added test.Boris Kolpackov1-1/+3
2004-01-08Enhancements to the documentation (fixes bugs #1772 and 4898).Paul Smith1-1/+1
Add "!" to the list of shell escape characters: POSIX sh allows it to be used to negate the return value of the command.
2004-01-07Fix order-only prerequisites for pattern rules. (Savannah patch #2349).Paul Smith1-3/+7
Add a regression test for this. Older libraries don't allow *alloc(0), so make sure we don't ever do that.
2003-05-02- Fix bug #1405: allow multiple pattern-specific variables to match a target.Paul Smith1-1/+1
- Fix some uncleanliness about the implementation of patterns-specific vars. - Some enhancements to the OS/2 port.
2002-10-14Convert the source code to use ANSI C style function definitions andPaul Smith1-8/+3
enable the automake ansi2knr capability. Right now this doesn't quite build using a K&R compiler because of a problem with the loadavg test program, but the rest of the code works. I'm asking the automake list about this problem.
2002-09-04Fix for complex situations where directories are declared as prerequisites.Paul Smith1-2/+2
Info on this fix from barkalow@reputation.com: thanks! Some updates/cleanups of some of the tests; added a forgotten -t test, etc.
2002-08-10Update to a new version of automake and gettext.Paul Smith1-1/+1
Invent a new macro HAVE_DOS_PATHS and change various instances of: #if defined(WINDOWS) || defined(__MSDOS__) to use the new macro instead. This should help make the OS/2 port cleaner, as well. Invent a cvs-clean maintainer target that tries to get the workspace back to the state it was in after a CVS checkout. New language.
2002-07-08Various cleanups reported by people using the alpha release.Paul Smith1-0/+3
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 Smith1-5/+8
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.
