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)
