Bug ID: 43782
Summary: Cannot profile clang-executables with instrumentation
in Visual Studio
Product: clang
Version: 9.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Tooling
Assignee: unassignedclangb...@nondot.org
Reporter: l...@hofst.com
CC: llvm-bugs@lists.llvm.org
If you try to profile an executable that was compiled with native clang on
Windows (even if it is linked with the MSVC linker) and you try to profile it
with instrumentation it will fail.
The error message indicates that the binary is not recognized.
It is really hard to research this problem but from what I found out, I believe
some pdb symbols are either wrong or incomplete.
This is basically a deal-breaker for choosing clang as an MSVC drop-in
replacement (although I would very much like to do so).
