------- Comment #2 from ro at gcc dot gnu dot org 2009-06-22 17:25 -------
Here's what the reghunt revealed:
* As of rev 148410, mainline ICEs building the 64-bit unwind-dw2-fde.o:
/vol/gcc/src/gcc-reghunt/libgcc/../gcc/unwind-dw2-fde.c:154:1: internal
compiler error: in dwarf2out_begin_epilogue, at dwarf2out.c:2752
This is fixed by applying the patch from Comment #1 of PR debug/40462. This
way, a C-only bootstrap finishes successfully.
* If I update this tree (with the patch) to rev 148411, I still get the ICE in
div_data_align. Thus, this patch
2009-06-11 Richard Henderson <r...@redhat.com>
* dwarf2out.c (def_cfa_1): Likewise for DW_CFA_cfa_offset.
* dwarf2out.c (need_data_align_sf_opcode): New.
(div_data_align): Move earlier.
(def_cfa_1, reg_save): Use it.
is the culprit.
