Bug ID: 47982
Summary: [asan] Shadowed stack variables' name are not the
exact source name.
Product: clang
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: LLVM Codegen
Assignee: unassignedclangb...@nondot.org
Reporter: pierregoussea...@gmail.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,
richard-l...@metafoo.co.uk
In the sample below the reported variable's name is the LLVM ir's name 'x1'
instead of 'x'.
Any ideas how to use the source's variable name instead?
Many thanks,
Pierre
