This is done by creating a named shared memory region, unlinking it and setting up a private (i.e. copy-on-write) mapping of that instead of a regular anonymous mapping. I've experimented with regular (sparse) files, but they can not be scaled to the size of MSan shadow mapping, at least on Linux/X86_64 and ext3 fs. Controlled by a common flag, decorate_proc_maps, disabled by default. This patch has a few shortcomings: * not all mappings are annotated, especially in TSan. * our handling of memset() of shadow via mmap() puts small anonymous mappings inside larger named mappings, which looks ugly and can, in theory, hit the mapping number limit. llvm-svn: 238621 |
