2017-05-12[msan] Remove a failing test from MemorySanitizer.ICmpRelationalAlexander Potapenko
This is a follow-up to r302787, which broke MemorySanitizer.ICmpRelational. MSan is now reporting a false positive on the following test case: TestForNotPoisoned((poisoned(-1, 0x80000000U) >= poisoned(-1, 0U))) , which is sort of anticipated, because we're approximating the comparison with an OR of the arguments' shadow values. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@302887 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: The build system was inconsistent in its naming conventions for link flags. This patch changes all uses of LINKFLAGS to LINK_FLAGS, for consistency with cmake's LINK_FLAGS property.

2016-04-20[msan] Implement GetPageSize in the test.Evgeniy Stepanov
Instead of calling a sanitizer_common function, implement GetPageSize in the test directly. MSan runtime does not export __sanitizer::* symbols, and the current code breaks when the test and the runtime library are in the separate link units (ex. when the test is built as a shared library). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@266910 91177308-0d34-0410-b5e6-96231b3b80d8
2016-04-18[msan] Don't hardcode 4kiB page size in msan_test.cc.Marcin Koscielnicki
This breaks the valloc test on PowerPC, which has 64kiB pages. Since getting page size portably is nontrivial, and there's already a function for that in __sanitizer, just use it. Unfortunately, sanitizer_common.h conflicts with the interface headers inclucded by msan_test.cc (and a few of its own macros), so we have to declare it manually.
