Created attachment 121277 [details] arm lse ldadd 32bit support SUMMARY currently there is no support for arm LSE instruction in guest_arm64_toIR.c. so any app contains LSE instruction will crash valgrind. STEPS TO REPRODUCE 1. create simple application and put an embedded LSE instruction into it, compile it to a.out 2. run valgrind ./a.out OBSERVED RESULT valgrind will crash with unknown instruction. EXPECTED RESULT valgrind works without crash SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION the attached patch added ldadd 32bit support, it's just a start to add whole LSE instructions support.
