Kostya Serebryany 739b0de5b1 [tsan] start using AllocatorCache in CombinedAllocator 
llvm-svn: 159825
 2012-07-06 14:32:00 +00:00
Alexander Potapenko 740d166c3e Small fix: do not replace the default CFAllocator if it has been replaced already.

Kostya Serebryany d1e6094f9e [tsan] implement SizeClassAllocatorLocalCache (part of tsan allocator) 
llvm-svn: 159823
 2012-07-06 13:46:49 +00:00
Alexander Potapenko dc211a8db4 Because CFAllocatorCreate() should also be called after __CFInitialize() on Lion, 
do so by factoring the CFAllocator logic into ReplaceCFAllocator(), which is called from
either the __CFInitialize wrapper or __asan_init(), depending on which of them is called later.

llvm-svn: 159822
 2012-07-06 13:24:28 +00:00
Alexander Potapenko 89f9270366 A portable way to check whether __CFInitialize has been called: compare kCFAllocatorSystemDefault._base._cfisa to 0. 
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=87 on both Lion and Snow Leopard.

llvm-svn: 159821
 2012-07-06 13:04:12 +00:00
Alexander Potapenko d2ff0b087a Do not check for __CFRuntimeClassTableSize on non-10.6 systems, where this symbol is private. 
This change may cause http://code.google.com/p/address-sanitizer/issues/detail?id=87 to re-appear on Lion.

Dmitry Vyukov 03d32ecd4f tsan: Go language support 
llvm-svn: 159754
 2012-07-05 16:18:28 +00:00
Alexander Potapenko 25b567dd0d Fix http://code.google.com/p/address-sanitizer/issues/detail?id=87 by making sure we replace the default CFAllocator only after __CFInitialize has been called.

Alexey Samsonov 38b1ec4317 [ASan] Add a default constructor for DWARFSection to initialize it with zeros. 
llvm-svn: 159748
 2012-07-05 14:28:37 +00:00
Dmitry Vyukov 5dc3f01676 tsan/asan: kill STL 
First, placement new from standard library conflicts with our own.
Second, we are in trouble if user uses the same function (we either get instrumented code in runtime, or non-instrumented code in user program).

Kostya Serebryany ba235522e0 [tsan] reg test for tsan issue #3 
llvm-svn: 159737
 2012-07-05 09:09:40 +00:00
Alexey Samsonov 78a3bbc82c [TSan] add a new option 'use_internal_symbolizer' that allows to choose between addr2line-based and llvm-based symbolizer w/o having to rebuild the runtime. This is hopefully a temporary solution that simplifies testing process. In the end, we should leave a single symbolizer.

Alexey Samsonov b4ea34f5d7 [TSan] Improve output tests: allow reports to contain file:line:column instead of file:line 
llvm-svn: 159714
 2012-07-04 15:48:05 +00:00
Alexander Potapenko 77769caaef Do not call malloc_zone_from_ptr() for the pointers passed to mz_size() and mz_free(). 
These callbacks assume that the memory belongs to asan_zone, so it's incorrect to pass it to another one.
If a need for this appears (e.g. system libraries free the memory using wrong zone), it should be documented.

Alexey Samsonov 3ac4548c92 [ASan] Minor fix in symbolizer output.

Alexey Samsonov 716aa7e2f2 [ASan] fixup for r159652 
llvm-svn: 159655
 2012-07-03 09:06:39 +00:00
Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.
