Alexey Samsonov	a788b940f7	[ASan] Fix PR17867 - make sure ASan doesn't crash if use-after-scope and use-after-return are combined. ... llvm-svn: 195014	2013-11-18 14:53:55 +00:00
Kostya Serebryany	cf880b9443	Unify clang/llvm attributes for asan/tsan/msan (LLVM part) ... These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S llvm-svn: 176075	2013-02-26 06:58:09 +00:00
Alexey Samsonov	29dd7f2090	[ASan] Fix lifetime intrinsics handling. Now for each intrinsic we check if it describes one of 'interesting' allocas. Assume that allocas can go through casts and phi-nodes before apperaring as llvm.lifetime arguments ... llvm-svn: 171153	2012-12-27 08:50:58 +00:00
Alexey Samsonov	261177a1e1	ASan: add initial support for handling llvm.lifetime intrinsics in ASan - emit calls into runtime library that poison memory for local variables when their lifetime is over and unpoison memory when their lifetime begins. ... llvm-svn: 169200	2012-12-04 01:34:23 +00:00
