Bug ID: 62014
Summary: [AArch64] Using -mgeneral-regs-only may lead to ICE
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

This patch should fix this issue, though it needs a test-case.
In some cases, when the LRA spills a register into an FP register, with the
option -mgeneral-regs-only specified, there is an ICE.
It seems to be caused by the LRA assuming that the FP registers are always
available and not being told when they aren't by the target.
