[PATCH] D32130: Move valid caller-pc checks out of platform-specific checks

[Francis Ricci via Phabricator via llvm-commits]

fjricci created this revision.

ProcessPlatformSpecificAllocations for linux leak sanitizer iterated over
memory chunks and ran two checks concurrently:

1. Ensured the pc was valid
2. Checked whether it was a linker allocation

All platforms will need the valid pc check, so it is moved out of the platform-
specific file. To prevent code and logic duplication, the linker allocation
check is moved as well, with the name of the linker supplied by the platform-specific
module. In cases where we don't need to check for linker allocations (ie Darwin),
this name will be a nullptr, and we'll only run the caller pc checks.
