| michael@0 | 10 | // |
| michael@0 | 11 | // Currently, these are: |
| michael@0 | 12 | // |
| michael@0 | 13 | // allow_user_segv_handler=1 - Tell ASan to allow our code to use its |
| michael@0 | 14 | // own SIGSEGV handlers. This is required by ASM.js internally. |
| michael@0 | 15 | // |
| michael@0 | 16 | // alloc_dealloc_mismatch=0 - Disable alloc-dealloc mismatch checking |
| michael@0 | 17 | // in ASan. This is required because we define our own new/delete |
| michael@0 | 18 | // operators that are backed by malloc/free. If one of them gets inlined |
| michael@0 | 19 | // while the other doesn't, ASan will report false positives. |
