Daniel Dunbar 587b1d419d Add new build option KERNEL_USE, which compiles with -mkernel and gets propogated to CFLAGS. Use this to call panic() instead of abort() when enabled. 
llvm-svn: 100015
 2010-03-31 17:00:48 +00:00
Daniel Dunbar f287008791 Use a private compilerrt_abort() define instead of calling abort directly. 
- Fiddling with abort directly is annoying given the way we use system includes, although it would be nice to fix this so we could make sure calling abort directly is verboten.

Daniel Dunbar d382d17f09 Update Apple-style build support for new Makefiles 
llvm-svn: 93721
 2010-01-18 06:49:42 +00:00
Daniel Dunbar efd84e770b Add support for "platform" configurations, which define a suite of compiler-rt 
libraries to generate.
 - Each library may be built with different flags and for different
   architectures, and there is support for building Darwin style fat archives.

 - Uses an ambituous amount of make programming, but should be hidden to
   users and developers.

 2010-01-18 06:48:48 +00:00
Daniel Dunbar 2d9816e44b Change subdir traversal to primarily cache information about what is available in subdirectories. 
- Rest of makefiles will move to using the information after it has been computed, instead of during subdir traversal.

Also, add 'make info-functions' target, which prints information on all the functions available in compiler-rt.

Also, add 'make help-devel' for listing help on targets intended for compiler-rt developers or direct users.

 2009-09-23 03:42:03 +00:00
Shantonu Sen 33f6acbbf1 1) Remove cmake-specific #define usage from the exported 
Block.h/Block_private.h headers, since clients won't know what to
set. These are moved into runtime.c as appropriate

2) Use cmake checks for CAS builtins, instead of guessing based on GCC
#defines (which aren't set by clang and llvm-gcc anyway)

3) "#pragma mark" isn't supported by FSF gcc, so "#if 0" it out. It
should still show up in IDEs that support it

4) Fix some compiler warnings. GCC 4.3.3 seems super strict about
%p. function pointers can't be cast to void * either.

5) Avoid a warning for apple_versioning.c that "ISO C does not allow
empty files"
