Dmitry Vyukov ecd73d36d4 asan/tsan: faster memory allocator 
replace lists with arrays

Kostya Serebryany 27ad15e165 [asan] asan_allocator2: store the user requested size in just 32 bits (larger sizes use metadata). This allows to put one more 32-bit field into the chunk header 
llvm-svn: 171089
 2012-12-26 04:52:07 +00:00
Kostya Serebryany eff9b4b9b1 [asan] add a test for right OOB with special large sizes. Fix this test in asan_allocator2. More test tweaking for allocator2 
llvm-svn: 171058
 2012-12-25 09:40:20 +00:00
Kostya Serebryany ad24c58e16 [sanitizer] increase the maximum size class of the fast allocator. This should save quite a bit of memory in tsan/msan (and later in asan). This also puts more stress on the large allocator. Add a couple of checks

 2012-12-25 07:50:35 +00:00
Kostya Serebryany fc7de2910c [sanitizer] make LargeMmapAllocator::GetBlockBegin faster by not using a linked list 
llvm-svn: 171035
 2012-12-24 14:35:14 +00:00
Kostya Serebryany ebb23c8cfa [sanitizer] rework the size class map in the sanitizer allocator: make the differences between size classes more uniform. 
llvm-svn: 171031
 2012-12-24 13:41:07 +00:00
Kostya Serebryany fe80f080ee [asan] asan_allocator2 fix two asserts that happen on full chrome: a) memalign called with 0 size and large alignment and b) malloc called after TSD has been destructed 
llvm-svn: 170900
 2012-12-21 14:54:46 +00:00
Kostya Serebryany a1e29adab5 [sanitizer] mmap less on every size class to make the allocator more friendly to small programs 
llvm-svn: 170895
 2012-12-21 13:38:05 +00:00
Kostya Serebryany 479f05b276 [asan] asan_allocator2: improve FindHeapChunkByAddress to find memory chunks to the left of a given address. Almost all tests pass with the new allocator now, only 6 are left to fix. 
llvm-svn: 170511
 2012-12-19 08:32:50 +00:00
Kostya Serebryany 2abbce6701 [sanitizer] one more stability fix in 64-bit allocator 
llvm-svn: 170498
 2012-12-19 06:51:45 +00:00
Kostya Serebryany 12676268fa [sanitizer] fix LargeMmapAllocator::GetBlockBegin 
llvm-svn: 170434
 2012-12-18 14:56:38 +00:00
Kostya Serebryany c8208c5258 [sanitizer] fix a bug that has crept into the sanitizer allocator and caused SEGV on allocations between 1Mb and 2Mb, improve the test 
llvm-svn: 170274
 2012-12-15 18:36:23 +00:00
Kostya Serebryany 9806628792 [sanitizer] introduce MmapFixedOrDie and use it in SizeClassAllocator64 
llvm-svn: 170099
 2012-12-13 05:36:00 +00:00
Kostya Serebryany 2ce42e0aef [sanitizer] change the way SizeClassAllocator64 allocated memory from the system: instead of one huge mmap(NORESERVE) it does one huge mprotect and then does small on-demand mmaps. This allows us to call OnMap callbacks which are required to poison newly allocated memory in asan 
llvm-svn: 170097
 2012-12-13 05:05:11 +00:00
Kostya Serebryany e29883c10a [sanitizer] add OnMap/OnUmap callbacks to the allocator interface

Kostya Serebryany 378f93e804 [sanitizer] fix the build on ancient gcc which has stricter rules about what can be put on TLS. Long term, we absolutely must build the run-times with the fresh target clang
