Added new file strcache.c to various non-UNIX makefiles and build scripts.
|
|
|
|
pattern rule also makes.
|
|
Try to avoid extraneous rebuilds of template files.

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.

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.

* New function: $(info ...)
* Disallow $(eval ...) to create prereq relationships inside command scripts
(caused core dumps)
* Try to allow more tests to succeed in Windows/DOS by sanitizing CRLF and \
* Various bug fixes and code cleanups (see the ChangeLog entry)

rules, static pattern rules and implicit rules.

Add "!" to the list of shell escape characters: POSIX sh allows it to be
used to negate the return value of the command.
|
|
Add a regression test for this.
Older libraries don't allow *alloc(0), so make sure we don't ever do that.

- Fix some uncleanliness about the implementation of patterns-specific vars.
- Some enhancements to the OS/2 port.
|
|
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.
|
|
Info on this fix from barkalow@reputation.com: thanks!
Some updates/cleanups of some of the tests; added a forgotten -t test, etc.
|
|
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.
|
|
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.
|
|
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.

* Fix problems with INTERMEDIATE rules.
|
|
|
|
* Apply changes from Paul Eggert.
* Many other cleanups (index/rindex --> strchr/strrchr, etc.)

|
* Various code cleanups.
|
|
targets need to have their modtimes rechecked (-n, etc.)
|
|
* 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.

It is not safe to store STEM's address because it might be auto storage.
