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.
llvm-svn: 27487
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.
llvm-svn: 27005
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.
llvm-svn: 26952
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)
llvm-svn: 26198
* 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
llvm-svn: 24891
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.
llvm-svn: 23006
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.
llvm-svn: 22424
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.
llvm-svn: 22198
* Check for availability of ffsll call in configure script
* Support ffs, ffsl, and ffsll conversion to constant value if the argument
is constant.
llvm-svn: 22027
script was defaulting the LLVMGCC variable to "llvm-gcc" if it couldn't
find llvm-gcc and --with-llvmgccdir was not specified. In this case, there
is no llvm-gcc available on the system so we shouldn't assume that the
user's path will find it any better than configure could. The fix is to
default it to an empty string. If LLVMGCC is empty, the makefiles will
avoid building things that depend on llvm-gcc and give a nice warning
message to that effect.
llvm-svn: 21953
--enable-target which can take values "all", "host-only" or a comma
separated list of target names (alpha,ia64,powerpc,skeleton,sparc,x86)
llvm-svn: 21447
options have been added to the configure script that control which targets
will be used. The options are:
--enable-target-this (default=disabled)
This will specify that the target corresponding to the build host is
the target that will be compiled/used. You can't use this with any of
the other options (they'll be ignored). This is what most people want.
--disable-target-x86 (default=enabled)
This will prevent the X86 target(s) from being compiled/used.
--disable-target-sparc (default=enabled)
This will prevent both SparcV8 and SparcV9 from being compiled/used.
--disable-target-powerpc (default=enabled)
This will prevent the PowerPC target from being compiled/used.
--disable-target-alpha (default=enabled)
This will prevent the Alpha target from being compiled/used.
--disable-target-ia64 (default=enabled)
This will prevent the IA64 target from being compiled/used.
Note that without any of these options, the default behavior is to build
all targets, as is the current practice.
All these options do is set up the substititution variable TARGETS_TO_BUILD
which contains the targets that should be compiled/used. The variable is
intended to be used in the makefiles. Those changes will come later.
llvm-svn: 21445
* Add CAN_DLOPEN_SELF so we can determine if dlopen(0) will open the
program or not.
* Correct a warning messages to be a little more specific on what it checks
llvm-svn: 19184
* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation
can be specified.
llvm-svn: 19142
Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System
llvm-svn: 19131
* Remove --with-llvmgccdir, not needed any more
* Search path for llvm-gcc and llvm-gxx
* Compute LLVMGCCDIR based on install path of llvm-gcc
llvm-svn: 19093
names that have version numbers in it so this macro, DJ_AC_PATH_TCLSH will
make the necessary checks. The makefile variable TCLSH is set to the path
found.
llvm-svn: 18382
* organize programs we test for properly
* add new programs needed for documentation generation
* Adjust install paths so llvm stuff doesn't muck up /usr/local or /usr if
$prefix is set to those.
llvm-svn: 18327
* cache more values
* standardize cache value names
* organize configure script per autoconf recommendations (10 sections)
* Eliminate some redundancies and complexities in the script
* Provide better documentation in the script.
llvm-svn: 18232
from the fray, so it gets noticed. This commit is made without the
corresponding configure script commit because it doesn't affect
functionality and we don't want to force everyone into another reconfigure
llvm-svn: 16657
from being re-generated if the new version is identical to the old version.
Hence, it should save us some recompiling after re-configures.
llvm-svn: 16506
Instead just create a warning message that says the directory cannot be
configured because it isn't recognized. This also gets rid of a bunch of
warning messages from the auto* tools.
llvm-svn: 16463
while still retaining the ability to configure unknown ones.
- Excise crud left over from when test/Projects was still part of the main
LLVM module. These removed tests are now all in
llvm-test/autoconf/configure.ac
llvm-svn: 16230
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.
llvm-svn: 16137
$BUILD_SRC_ROOT/lib/System/$build which gives us the ability to
configure the lib/System for the current type of operating system.
Also cleaned up some indentation.
llvm-svn: 16082
Add basic installation directories as AC_DEFINES and AC_SUBST so they can
be used by llvm programs with a simple #include <Config/config.h>
llvm-svn: 15942
DataTypes.h. So far, it doesn't seem to break Linux, Solaris, or MacOS X.
This should automatically include it for those people who need it.
llvm-svn: 15006
