https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202766 Bug ID: 202766 Summary: devel/valgrind: unhandled sysarch cmd 132 (AMD64_GET_XFPUSTATE) Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: vedge@hypertriton.com On 10.2-STABLE, when running some threaded applications with valgrind, I'm seeing: ==31628== unhandled sysarch cmd 132 ==31628== Valgrind detected that your program requires ==31628== the following unimplemented functionality: ==31628== unhandled sysarch cmd ==31628== This may be because the functionality is hard to implement, ==31628== or because no reasonable program would behave this way, ==31628== or because nobody has yet needed it. In any case, let us know at ==31628== www.valgrind.org and/or try to work around the problem, if you can. ==31628== ==31628== Valgrind has to exit now. Sorry. Bye! ==31628== sched status: running_tid=1 Thread 1: status = VgTs_Runnable ==31628== at 0x715EF0A: sysarch (in /lib/libc.so.7) ==31628== by 0x7130871: __fillcontextx2 (in /lib/libc.so.7) ==31628== by 0x6EC1630: ???

(in /libexec/ld-elf.so.1) ==31628== by 0x4002438: ??? (in /libexec/ld-elf.so.1) I don't know how valgrind should be emulating AMD64_GET_XFPUSTATE, but the attached patch can be used to work around the problem by pretending it is unimplemented. -- You are receiving this mail because: You are the assignee for the bug.
