Hey,
This patch adds support for the Cortex-X4 CPU to GCC.
Regression testing for aarch64-none-elf target and found no regressions.
Okay for gcc-master? I don't have commit access so if it looks okay,
could someone please help me commit this?
Thanks,
Saurabh
gcc/ChangeLog
* config/aarch64/aarch64-cores.def (AARCH64_CORE): Add support for
cortex-x4 core.
* config/aarch64/aarch64-tune.md: Regenerated.
* doc/invoke.texi: Add command-line option for cortex-x4 core.
Apologies, I forgot to add the patch file on my previous email.
