| * | [NewPM] Port Msan | Philip Pfaffe | 2019-01-03 | 1 | -0/+6 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Keeping msan a function pass requires replacing the module level initialization: That means, don't define a ctor function which calls __msan_init, instead just declare the init function at the first access, and add that to the global ctors list. Changes: - Pull the actual sanitizer and the wrapper pass apart. - Add a newpm msan pass. The function pass inserts calls to runtime library functions, for which it inserts declarations as necessary. - Update tests. Caveats: - There is one test that I dropped, because it specifically tested the definition of the ctor.

| * | [msan] Relax origin-alignment test. | Evgeniy Stepanov | 2015-11-24 | 1 | -5/+4 |
| | | | | | | | | | | Change origin-alignment test to test only the alignment of the origin store, and not the exact instruction sequence used to compute the address. This makes the test less fragile and, in particular, lets it pass both with the old and new MSan ABIs. llvm-svn: 254027 | ||||
| * | New MSan mapping layout (llvm part). | Evgeniy Stepanov | 2015-10-08 | 1 | -4/+6 |
| | | | | | | | | | | | | | | | | | | | This is an implementation of https://github.com/google/sanitizers/issues/579 It has a number of advantages over the current mapping: * Works for non-PIE executables. * Does not require ASLR; as a consequence, debugging MSan programs in gdb no longer requires "set disable-randomization off". * Supports linux kernels >=4.1.2. * The code is marginally faster and smaller. This is an ABI break. We never really promised ABI stability, but this patch includes a courtesy escape hatch: a compile-time macro that reverts back to the old mapping layout. llvm-svn: 249753 | ||||
| * | [msan] Avoid extra origin address realignment. | Evgeniy Stepanov | 2014-12-05 | 1 | -0/+73 |
| Do not realign origin address if the corresponding application address is at least 4-byte-aligned. Saves 2.5% code size in track-origins mode. llvm-svn: 223464 | |||||
