[asan] don't instrument globals that we've created ourselves (reduces the binary size a bit) llvm-svn: 167230 2012-11-01 21:42:40 +08:00			`; This test checks that we are not instrumenting globals`

[ASan] Add -asan-module to the ASan .ll tests. After the -asan pass had been split into -asan (function-level) and -asan-module (module-level) some of the tests have silently stopped working, because they didn't instrument the globals anymore. We've decided to have every test using both passes, irrespective of the presence of globals in it. llvm-svn: 204335 2014-03-20 19:16:34 +08:00			`; RUN: opt < %s -asan -asan-module -S \| FileCheck %s`

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 14:58:09 +08:00			`define void @_Z3barv() uwtable sanitize_address {`

[asan] when creating string constants, set unnamed_attr and align 1 so that equal strings are merged by the linker. Observed up to 1% binary size reduction. Thanks to Anton Korobeynikov for the suggestion llvm-svn: 177264 2013-03-18 17:38:39 +08:00			`; It should have unnamed_addr and align 1.`

[ASan] Fix the tests broken by r198018 to check for private linkage of ASan-generated globals. llvm-svn: 198020 2013-12-26 01:06:04 +08:00			`; CHECK: = private unnamed_addr constant{{.*}}align 1`
