[Bug target/61633] New: AArch64 SISD ASHR instruction split clobbers input register.

Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: mshawcroft at gcc dot gnu.org The FFT code in Android AAC codec at -O2 is incorrectly compiled resulting in an infinite loop. I've failed to reduce the test case to something usable but the problem in the back end is clearly the define_splits associated with *aarch64_ashr_sisd_or_int_3. Both of the splits inappropriately use one of the input operand register as a scratch pad for the negated shift operand.
