Bug ID: 523843
Summary: Check stack alignment in doHelperCall
Classification: Developer tools
Product: valgrind
Version First 3.27 GIT
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Bug 523626 shows how the MOVDQA fails to work when Valgrind compiled with Clang
-O2 runs an x86 program. The reason appears to be missing 16 byte stack
alignment needed by the SIMD instructions.
Bug 523626 handles one such specific case (none/tests/x86/sse4-x86). This bug
is an attempt to find a generic solution to this problem.
