http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49423 --- Comment #16 from Dinar Temirbulatov 2012-10-11 09:11:27 UTC --- this regression after PR43137, also absence of pool range predicates for arm_zero_extendqisi2, arm_zero_extendqisi2_v6, arm_zero_extendhisi2, arm_zero_extendhisi2_v6 caused gcc.c-torture/compile/920928-2.c to fail with ICE by using -Os flag.

I get this same ICE while compiling gcc.c-torture/execute/scal-to-vec2.c at -O1
with a 4.7 configured with --with-arch=armv7-a --with-fpu=vfp
--with-float=hard .
(gdb) p debug_rtx(insn)
(insn 357 1038 1041 (set (reg:SI 14 lr)
(zero_extend:SI (mem/u/c:HI (symbol_ref/u:SI ("*.LC0") [flags 0x2]) [0
S2 A16]))) t.c:49 161 {*arm_zero_extendhisi2_v6}
(nil))
$4 = void
Both arm_zero_extendhisi2 and arm_zero_extendhisi2_v6 are missing
pool_range/neg_pool_range .
