2016-03-09sanitizer: Fix endianness checks for gccAlexey Samsonov
Summary: __BIG_ENDIAN__ and __LITTLE_ENDIAN__ are not supported by gcc, which eg. for ubsan Value::getFloatValue will silently fall through to the little endian branch, breaking display of float values by ubsan. Use __BYTE_ORDER__ == __ORDER_BIG/LITTLE_ENDIAN__ as the condition instead, which is supported by both clang and gcc. Noticed while porting ubsan to s390x. Patch by Marcin Kościelnicki!

2016-02-22[Sanitizer] Introduce ListOfModules object and use it to replace ↵Alexey Samsonov
GetListOfModules(). Summary: This removes the hard limit on the number of loaded modules (used to be 16K), and makes it easier to use LoadedModules w/o causing a memory leak: ListOfModules owns the modules, and makes sure to properly clean them in destructor. Remove filtering functionality that is only needed in one place (LSan).

2015-08-11[Windows] Use llvm-symbolizer before using dbghelpReid Kleckner
Summary: llvm-symbolizer understands both PDBs and DWARF, so it's a better bet if it's available. It prints out the function parameter types and column numbers, so I needed to churn the expected test output a bit. This makes most of the llvm-symbolizer subprocessing code target-independent. Pipes on all platforms use fd_t, and we can use the portable ReadFromFile / WriteToFile wrappers in symbolizer_sanitizer.cc. Only the pipe creation and process spawning is Windows-specific. Please check that the libcdep layering is still correct. I don't know how to reproduce the build configuration that relies on that.

2014-07-26[Sanitizer] Simplify Symbolizer creation interface.Alexey Samsonov
Get rid of Symbolizer::Init(path_to_external) in favor of thread-safe Symbolizer::GetOrInit(), and use the latter version everywhere. Implicitly depend on the value of external_symbolizer_path runtime flag instead of passing it around manually.

2013-10-25Overhaul the symbolizer interface.Peter Collingbourne
This moves away from creating the symbolizer object and initializing the external symbolizer as separate steps. Those steps now always take place together. Sanitizers with a legacy requirement to specify their own symbolizer path should use InitSymbolizer to initialize the symbolizer with the desired path, and GetSymbolizer to access the symbolizer. Sanitizers with no such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for initialization. The symbolizer interface has been made thread-safe (as far as I can tell) by protecting its member functions with mutexes. Finally, the symbolizer interface no longer relies on weak externals, the introduction of which was probably a mistake on my part.
