are available. These libraries are used in lib/System and should be
included on the link line or if not available generate an error when
building lib/System.

and is unlikely to change in future releases. This also simplifies the
parsing of the full and major llvm-gcc version numbers in the script.

If we fail to find a required program, simply set that program to echo
out something that tells the user the situation. That is, instead of just
"true runtest" we now get "echo 'Skipped: runtest not found'".

1. Assertions now default to on for all builds
2. If you want them disabled you must (a) --disable-assertions to configure
or DISABLE_ASSERTIONS=1 to make.
llvm-svn: 27548
Support detection of a "CVS" directory at configure time to distinguish
whether this is a release build or a "from tree" build. This knowledge is
used to set the defaults for --enable-optimzied and --enable-assertions
options.

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.
This version is now ready for testing by users.

is a handy tool for users of LLVM who want to be able to quickly get
information about LLVM's configuration. It is intended to be used in the
command line of other tools. Documentation will be forthcoming in a
subsequent patch.

go through, but we do want to know if we're using GCC/ICC since they
share certain funky command line options (for dependency generation
stuff)

* Add --enable-debug-runtime option, defaults to disabled
* Pass the new config var, DEBUG_RUNTIME, to Makefiles
* Don't use -Wa,-strip-debug if debug-runtime is enabled

Make any header files that are automatically generated be preconditions of
the compilation. This ensures that if a *.h.in file is changed then its
corresponding *.h file gets updated on the next rebuild. Note that this can
lead to confusing (but correct) results if the *.h.in file changed
unsubstantially so that autoheader doesn't update the *.h file. In that case,
manually touch the *.h file in question to restore order. Moral of the story,
if you're going to "touch" a *.in file then modify it substantially.

These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class
will be implemented with all functions as no-op. Furthermore, linking against
libpthread will not be done. Finally, the ParallelJIT example needs libpthread
so its makefile was changed to always add -lpthread to the link line.
llvm-svn: 23003
GRAPHVIZ will contain the path to the program if its found (or "echo Graphviz"
if not) and the #define HAVE_GRAPHVIZ will be defined if its found.

This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
The implementation of MutexGuard.h is now based on sys::Mutex which hides
its implementation and makes it unnecessary to have the -NoSupport.h and
-PThreads.h versions of ThreadSupport.
* All places in ExecutionEngine that previously referred to "Mutex" now
refer to sys::Mutex
* All places in ExecutionEngine that previously referred to "MutexLocker"
now refer to MutexGuard (this is frivolous but I believe the technically
correct name for such a class is "Guard" not a "Locker").
These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.
llvm-svn: 22404
Make sure that -lpthread gets added to LIBS variable which puts it at the
end of the tools' link commands, if libpthread.a is found.
Add a test for pthread.h so we can use #ifdef HAVE_PTHREAD_H
llvm-svn: 22401
still possible to force V9 (even if configure doesn't think it's one) via
``./configure --target=sparcv9-sun-solaris2.8'' so nothing is lost.
