Dmitry Vyukov 7d3d94454c tsan: improve memory allocator a bit
llvm-svn: 162561

Dmitry Vyukov 7e6347402d tsan: fix new memory allocator
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.

Alexey Samsonov 563fb4113c [Sanitizer] Add external symbolizer binary. Next steps - include it in CMake build (produce 32-bit and 64-bit version of it, make sure we can compile LLVM sources with our own flags) and add tests for it.

Alexey Samsonov 419f610a74 [Sanitizer] Switch the symbolization strategy that would be used by sanitizer tools family: as compiling in-process symbolizer into runtime involves certain difficulties, we may instead launch an external symbolizer program (fork + execl) in a subprocess and communicate with it via pipe.

2012-08-21 09:26:26 +00:00
Alexey Samsonov e6704ee109 [Sanitizer] define InternalScopedBuffer to replace large arrays on stack. It is defined analogous to similar class in tsan and should replace it.

Alexey Samsonov 500e99639d [Sanitizer] Wrapper around llvm::DIContext from LLVM DebugInfo library. If a macro SANITIZER_USES_LLVM_LIBS is defined (by default it is not), then sanitizer runtime includes llvm headers and tries to use LLVM libs for in-process symbolization. To make it functional, we have to link with these LLVM libs - either pass them to linker from Clang driver, or link them into static ASan runtime when we build it.

Alexey Samsonov 7acdc1738f [Sanitizer] When obtaining the data for loaded modules, add address ranges of loadable segments only. Looks like address range of PT_TLS segment may intersect with loadable segments of other modules.

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).

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.
