[PATCH] D31484: [asan] Support line numbers in StackVarDescr

[Kuba (Brecka) Mracek via Phabricator via llvm-commits]

kubamracek created this revision.
kubamracek added a project: Sanitizers.

When `-fsanitize-address-use-after-scope` is used, the instrumentation produces line numbers in stack frame descriptions.  This patch make sure the ASan runtime supports this format (ParseFrameDescription needs to be able to parse "varname:line") and prepares lit tests to allow line numbers in ASan report output.
