FAIL: gcc.dg/long_branch.c (test for excess errors)
It didn't fail 2 days ago, I suspect the RTL SSA changes.

--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Strangely, it doesn't reproduce under gdb, nor when cc1 is 64-bit binary with
-m32 -mno-sse -march=pentiumpro -mtune=pentiumpro on top of the normal test
flags.

Bah, stupid thinko: using regno_raw_mode[regno] instead of
GET_MODE (regno_reg_rtx[regno]) for general registers :-(
Testing a fix.

rtl-ssa: Fix reg_raw_mode thinko [PR98347]
I'd used reg_raw_mode[regno] for general registers, even though
the array is only valid for hard registers. This patch uses
regno_reg_rtx instead.
gcc/
PR rtl-optimization/98347
* rtl-ssa/access-utils.h (full_register): Use regno_reg_rtx
instead of reg_raw_mode.
