Robert Clausecker <[email protected]> has asked freebsd-x11 (Nobody) <[email protected]> for maintainer-approval: Bug 263845: graphics/libglvnd: Library compiled in ARM mode, but executes in Thumb mode, crashing programs on FreeBSD 13 armv7 with SIGILL https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263845 Attachment 234353: graphics/libglvnd: fix on armv7 https://bugs.freebsd.org/bugzilla/attachment.cgi?id=234353&action=edit --- Comment #4 from Robert Clausecker <[email protected]> --- Created attachment 234353 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=234353&action=edit graphics/libglvnd: fix on armv7 The .thumb_func directive does not switch to thumb mode in clang's integrated assembler. This causes the code to be miscompiled in that it is generated as ARM code but the symbols are tagged as thumb. The resulting library is unusable. Every call into it crashes. Add a patch to fix the behaviour and bump PORTREVISION so consumers get the updated library. Tested with Poudriere on armv7 FreeBSD 13. Please MFH if possible.
