We forcecallback instrumentation to simplify the initial aliasingimplementation.Reviewed By: vitalybuka, eugenisDifferential Revision: https://reviews.llvm.org/D98069 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/stack-uar-dynamic.c Mon, 22 Mar 2021 15:01:48 +0000 Matt Morehouse <mascasa@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/stack-uar-dynamic.c#d11ea651 hwasan: Teach the runtime to identify the local variable being accessed in UAR reports.Each function's PC is recorded in the ring buffer. From there we can accessthe function's local variables and reconstruct the tag of each one with thehelp of the information printed by llvm-symbolizer's new FRAME command. Wecan then find the variable that was likely being accessed by matching thepointer's tag against the reconstructed tag.Differential Revision: https://reviews.llvm.org/D63469llvm-svn: 364607 List of files: /llvm-project-15.0.7/compiler-rt/test/hwasan/TestCases/stack-uar-dynamic.c Thu, 27 Jun 2019 23:16:13 +0000 Peter Collingbourne <peter@pcc.me.uk>
