Summary: [4.4/4.6 Regression] unrecognized insn storing fp
(simd) reg in SImode to stack
Product: gcc
Version: 4.4.5
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: h...@gcc.gnu.org
Target: sparc64-unknown-linux-gnu
Created attachment 24148
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24148
preprocessed trivially reduced test-case
Most likely also 4.5 and "4.7" but I don't have a corresponding build tree
handy.
Flagged as a regression because 4.3.5 builds it.
Anyway, observe the following ICE with the attachment compiled with "cc1
-fpreprocessed -mptr64 -mstack-bias -mlong-double-128 -m64 -mcpu=ultrasparc
-mvis -O2 -o rc_stat.s rcs5.i" (for 4.4.5):
