Bug ID: 59787
Summary: [ARM] mmx-2.c causes ICE when GCC is configured for
cortex-a5/vfpv3-d16-fp16
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: christophe.lyon at st dot com
I've noticed that gcc.target/arm/mmx-2 causes GCC to crash when GCC is
configured as:
--target=arm-none-linux-gnueabihf
--with-cpu=cortex-a5
--with-fpu=vfpv3-d16-fp16
testsuite/gcc.target/arm/mmx-2.c:166:1: internal compiler error: Max. number of
generated reload insns per insn is achieved (90)
0x9a5a32 lra_constraints(bool)

--- Comment #1 from Renlin Li <renlin.li at arm dot com> ---
Confirm that, gcc.target/arm/mmx-2.c cause an ICE with the following
configuration.
--target=arm-none-linux-gnueabihf
--with-arch=armv7-a
--with-fpu=vfpv3-d16
--with-float=softfp
(insn 51 50 52 2 (set (reg:DI 534 [orig:139 D.4720 ] [139])
(mem/v/c:DI (plus:SI (reg/f:SI 102 sfp)
(const_int -20 [0xffffffffffffffec])) [0 llsink+0 S8 A64]))
mmx-2.c:4
2 447 {*iwmmxt_arm_movdi}
(nil))
(insn 573 0 0 (set (reg:DI 139 [ D.4720 ])
(reg:DI 534 [orig:139 D.4720 ] [139])) -1
(nil))
lra_constraints() keeps reloading <reg 139> until Max. number of reload insns
is reached.
