https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206066 Bug ID: 206066 Summary: base/projects/clang380-import's clang crashed targeting armv6 and requested a submittal Product: Base System Version: 11.0-CURRENT Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: markmi@dsl-only.net Created attachment 165306 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D165306&action= =3Dedit .zip of the /tmp/*.c and *.sh that clang left for the report I tried -Oz (for smaller code) to see if I could get linking involving cc1_= main to work for armv6 during buildworld of -r293430 (amd64 cross build targeting armv6). clang crashed and requested a submittal. (buildworld gets relocation truncations while linking and stops with default optimizations in my contex= t.) # gdb clang /var/crash/clang.40580.core=20 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc. . . .
