 2012-09-07 19:57:23 +00:00
Chandler Carruth 1aa4fef601 Relocate the external headers provided by ASan and the common sanitizer 
library.

These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.

I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.

I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.

The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:

  <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
  <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
  <prefix>/lib/clang/X.Y/include/sanitizer/...

But maybe others have different suggestions?

Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

the right thing.

Daniel Dunbar cdf9bf7048 make/clang_darwin: Tweak CheckArches function to force the integrated-as and use 
the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.

Daniel Dunbar 2aa900834e build: Sketch a Clang/Linux platform config. 
- Currently just tries to build a full library for i386/x86_64.

 - This is made substantially more complicated by the lack of a generalized way
   to check for/invoke cross compilers. For now, we just try and make it work
   for the matched arch, and rely on the host CC being Clang.

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.

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.
