Evgeniy Stepanov 0af672326a [sanitizer] Replace more platform checks with SANITIZER_ constants. 
llvm-svn: 177400
 2013-03-19 14:33:38 +00:00
Alexey Samsonov 3a6b6b9d55 [Sanitizer] Don't intercept frexpf and frexpl on Windows. Add frexp declaration to asan_intercepted_functions.h

Kostya Serebryany 1d63d13ce2 [asan] move the .preinit_array hack into a separate file (added used attribute)

Alexander Potapenko b8135a8a6b [ASan] Put several function prototypes back under #ifdef _WIN32 to fix the Windows build. 
llvm-svn: 175743
 2013-02-21 15:10:03 +00:00
Alexander Potapenko e8ba1c851a [ASan] Refactoring: nuke the redundant function declarations in asan_intercepted_functions.h 
that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.

Alexander Potapenko 70b01558f1 [ASan] Delete asan/dynamic dir and temporarily move the interposers declarations to asan_intercepted_functions.h 
Now that we have only one dependency on asan_intercepted_functions.h, we can unite that code with the interceptors declarations in asan_interceptors.cc and get rid of asan_intercepted_functions.h

Evgeniy Stepanov ea61d08185 [sanitizer] Add interceptors for localtime and friends.

 2013-02-12 12:45:29 +00:00
Alexander Potapenko 09aba10499 [ASan] fix the interceptor for siglongjmp. As we're using dylib interposition, we must intercept both siglongjmp and longjmp on Darwin. 
llvm-svn: 174510

Alexander Potapenko 34157fc33f [ASan] Delete the code related to static runtime on OS X. 
Nuke lib/interception/mach_override.

Alexander Potapenko 56a3724cf1 [ASan] fix compilation on Mac by adding a missing pwrite parameter. 
llvm-svn: 173333
 2013-01-24 09:15:08 +00:00
Alexander Potapenko cae42d23a6 [ASan] Use dylib interposition to hook memory allocation in the dynamic runtime. 
This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

Jakob Stoklund Olesen 7956e0094d Revert r172719, r172721-172723, and r172725. 
The r172719 patch broke the build on Mac, the others depended on it.

Alexander Potapenko 0dcd6d9468 [ASan] Do not build the interceptors that use ObjC blocks if the compiler does not support blocks. 
Need to define MISSING_BLOCKS_SUPPORT in this case at buildtime.

Alexander Potapenko 2ebe619340 Re-implement the wrappers for libdispatch functions using blocks where appropriate 
(kudos to Anna Zaks for a good example).
This simplifies the code much and lets us not implement internal parts of libdispatch.

All ASan tests from t32 and t64 should pass with the dylib runtime now.
