http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52425 Mikael Pettersson changed: What|Removed |Added CC||mikpe at it dot uu.se --- Comment #1 from Mikael Pettersson 2012-02-29 12:41:15 UTC --- I can reproduce the ICE with a cross to sparc64-linux and -fPIC -g -O2 -std=gnu99 -pthread -S -m32 -mcpu=v8. The ICE stopped occurring on trunk with r171154: http://gcc.gnu.org/ml/gcc-cvs/2011-03/msg00576.html http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01114.html However that's merely a minor IRA cost tweak with no SPARC-specific bits, so I suspect the problem is elsewhere.

For some reason I can never reproduce sparc bugs with cross compilers. The
original testcase doesn't fail here; the reduced one fails but with a different
error message, and it fails in instantiate_virtual_regs which is before any
head-merging ever runs:
sparcbug.i: In function ‘action_button_cb’:
sparcbug.i:57:1: error: unrecognizable insn:

Please post the actual command line that gets passed to cc1. Also, it would be
helpful if you could load cc1 into a debugger and do the following at the crash
site in output_addr_const:
(gdb) p debug_rtx (x)
and at some higher level, also use debug_rtx to print out the insn it's trying
to print.
