Bug ID: 472405
Summary: RFE: give Note about instructions on current hardware
that are not supported by VEX
Classification: Developer tools
Product: valgrind
Version: unspecified
Platform: PCLinuxOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: jrei...@bitwagon.com
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
Request For Enhancement (RFE): At run-time initialization, then memcheck should
give a Note about cpu instructions on the current executing hardware, that VEX
does not support. Such as: "Note: this version of valgrind does not support
these instructions of this CPU: aes bmi1 bmi2". Such a Note would enhance
usability by giving early warning of Unrecognized Instruction. Getting a
friendly warning at the beginning, instead of "vex amd64->IR: unhandled
instruction bytes: 0x..." and several lines of spew, is much more pleasant.
