![]() The current DWARF info for CR are incorrect, causing the gcc unwinder to go to lunch if we take a segfault in the vdso. This fixes it. Problem identified by Andrew Haley, and fix provided by Jakub Jelinek (thanks !). Unfortunately, a bug in gcc cause it to not quite work either, but that is being fixed separately with something around the lines of: linux-unwind.h: fs->regs.reg[R_CR2].loc.offset = (long) ®s->ccr - new_cfa; + /* CR? regs are just 32-bit and PPC is big-endian. */ + fs->regs.reg[R_CR2].loc.offset += sizeof (long) - 4; (According to Jakub) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org> |
