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.

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.

If -R is set in the makefile and not the command line, then go through all the
default variables and undefine them. If -r is set in the makefile and not in
the command line, then remove all .SUFFIX prefixes (unless the user set it)
and SUFFIX variable setting. In -p mode don't print builtins.

This allows you to write portable makefiles that set GNU make-specific command
line options in the environment or makefile: add them to GNUMAKEFLAGS instead
of MAKEFLAGS and they will be seen by GNU make but ignored by other
implementations of make.

The new GNU Maintainer's Manual allows the use of year ranges in certain
situations; take advantage of this simplification.

it might be needed: for most situations we parse prereqs immediately as
we used to. Reduces memory usage.
- Fixes Savannah bug #18622.
|
|
- 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
|
|
- Fix Savannah bug 21231

* Update copyright to 2007
* Fix download URL for translation files (thanks to Thiemo Seufer)

Fix an uninitialized variable.
Add builtin rules for Objective C.
Add a new debug line that shows where the commands that are about to be run
were defined.

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.

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.

- 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.

Added new file strcache.c to various non-UNIX makefiles and build scripts.
|

When rebuilding makefiles, unset -B if MAKE_RESTARTS is >0.

|
- OS/2 Patches
- OpenVMS updates
- Sanitize the handling of -include/sinclude with and without -k
- Fix the setting of $< for order-only rules.
|
|
- Fix some uncleanliness about the implementation of patterns-specific vars.
- Some enhancements to the OS/2 port.
|
|
Also a small patch from Hartmut Becker <Hartmut.Becker@compaq.com> for VMS.

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.
|
|
* Define COFLAGS to avoid unknown variable warning.
* Fix some usec problems on UnixWare.
* Don't remove .INTERMEDIATE targets specified on the command line.
|
|
* Clean up some warnings.
|
|
|
|
* Apply changes from Paul Eggert.
* Many other cleanups (index/rindex --> strchr/strrchr, etc.)
|
|
* Installed Tim Magill's "graph pruning" performance enhancement.
* Update version to 3.77.90 for the release.
* Require automake 1.4.
|
|
|
|
* 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.
|
|
* A few tweaks to the system glob test, after trying it on a system where
it's true.
* Installed patches to archive handling for AIX 4.3 big archives.
* Fix a memory stomp in target-specific variables.
* Fix a memory leak in foreach functions.

Existence of the `f' flag is not consistent across HPUX versions;
and one might be using GNU ar anyway.

(default_suffix_rules) [__MSDOS__]: Use `y_tab.c' instead of `y.tab.c'.
(default_variables) [GCC_IS_NATIVE]: Set CC and CXX to `gcc', YACC to
`bison -y', and LEX to `flex'.
