2015-12-10[TSan] Try harder to avoid compiler-generated memcpy calls.Alexey Samsonov
check_memcpy test added in r254959 fails on some configurations due to memcpy() calls inserted by Clang. Try harder to avoid them by using internal_memcpy() where applicable. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@255287 91177308-0d34-0410-b5e6-96231b3b80d8
2015-11-30[tsan] Fix weakly imported functions on OS XKuba Brecka
On OS X, for weak function (that user can override by providing their own implementation in the main binary), we need extern `"C" SANITIZER_INTERFACE_ATTRIBUTE SANITIZER_WEAK_ATTRIBUTE NOINLINE`. Fixes a broken test case on OS X, java_symbolization.cc, which uses a weak function __tsan_symbolize_external.

2014-12-02Simplify Symbolizer::SymbolizePC() interface.Alexey Samsonov
Return a linked list of AddressInfo objects, instead of using an array of these objects as an output parameter. This simplifies the code in callers of this function (especially TSan). Fix a few memory leaks from internal allocator, when the returned AddressInfo objects were not properly cleared. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@223145 91177308-0d34-0410-b5e6-96231b3b80d8

2014-11-04[TSan] Don't strip binary/library name until the moment we print it.Alexey Samsonov
This commit changes the place where TSan runtime turns full path to binary or shared library into its basename (/usr/foo/mybinary -> mybinary). Instead of doing it as early as possible (when we obtained the full path from the symbolizer), we now do it as late as possible (right before printing the error report). This seems like a right thing to do - stripping to basename is a detail of report formatting implementation, and should belong there. Also, we might need the full path at some point - for example, to match the suppressions. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@221225 91177308-0d34-0410-b5e6-96231b3b80d8

2014-09-10[Sanitizer] Get rid of Symbolizer::Get() and Symbolizer::GetOrNull().Alexey Samsonov
We may as well just use Symbolizer::GetOrInit() in all the cases. Don't call Symbolizer::Get() early in tools initialization: these days it doesn't do any important setup work, and we may as well create the symbolizer the first time it's actually needed. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@217558 91177308-0d34-0410-b5e6-96231b3b80d8

2013-10-31[Sanitizer] Add Symbolizer::AddHooks() and use it in TSan and MSan.Alexey Samsonov
Summary: TSan and MSan need to know if interceptor was called by the user code or by the symbolizer and use pre- and post-symbolization hooks for that. Make Symbolizer class responsible for calling these hooks instead. This would ensure the hooks are only called when necessary (during in-process symbolization, they are not needed for out-of-process) and save specific sanitizers from tracing all places in the code where symbolization will be performed.

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.
