2006-02-06Fix Savannah bugs # 15341, 15534, and 15533.Paul Smith1-8/+14
Rewrite large chunks of the "Commands" section of the manual to better describe then backslash-newline handling, the SHELL variable, etc.
2005-10-24Make second expansion optional (partial implementation).Paul Smith1-76/+152
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 Smith1-20/+35
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.

2004-09-21Fixed bug in implicit rule prerequisite evaluation code. Added test.Boris Kolpackov1-1/+2
2004-05-16Various enhancementsPaul Smith1-1/+5
- OS/2 Patches - OpenVMS updates - Sanitize the handling of -include/sinclude with and without -k - Fix the setting of $< for order-only rules.

Small fixes for W32 (from Jonathan Grant <jg-make@jguk.org>) Maintainer enhancements to clean up the tree.
2004-01-21Many bug fixes etc.Paul Smith1-0/+3
- Apply a fix for the "thundering herd" problem when using "-j -l". This also fixes bug #4693. - Fix bug #7257: allow functions as ifdef arguments - Fix bug #4518: make sure we print all double-colon rules with -p. - Upgrade to autconf 2.58/automake 1.8/gettext 0.13.1 - Various doc cleanups, etc.
2003-03-28Fix bug #2515: the .SECONDARY target with no prerequisites wasn'tPaul Smith1-1/+13
behaving properly (if you listed prerequisites it worked properly).
2003-03-25Fix bug #2892.Paul Smith1-1/+1
More OS/2 updates from Andreas Buening. Upgrade build system to autoconf 2.57 and automake 1.7.3.
2002-10-14Convert the source code to use ANSI C style function definitions andPaul Smith1-38/+20
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.

2002-08-01New variables, .VARIABLES and .TARGETS.Paul Smith1-0/+49
2002-07-11Install Greg McGary's patches to port the id-utils hashing functions toPaul Smith1-277/+221
GNU make. Also he provides some other performance fixups after doing some profiling of make on large makefiles. Modify the test suite to allow the use of Valgrind to find memory problems.
2002-07-09Documentation and tests for order-only prerequisites.Paul Smith1-2/+17
Add a new test suite for automatic variables.
2002-05-10Fix Debian bug #144306: pass target-specific variables into the environmentPaul Smith1-1/+2
properly. Fix configure: allow cross-compilation; fix getloadavg (still needs _lots_ of work!) Let $(call ...) functions to be self-referencing. Lets us do transitive closures, for example.
