Hi all,
I've decided to organise the aarch64 macro fusion patches into a series.
Some of them have been posted last week and gotten review feedback
and have been reworked:
- [1/5] Implement TARGET_SCHED_MACRO_FUSION_PAIR_P:
This implements the hook itself and adds logic for fusing
MOV+MOVK instructions as used when synthesising immediates.
- [2/5] Implement adrp+add fusion:
Implements fusion of ADRP+ADD instructions when the
appropriate register dependencies are met.
- [3/5] Implement fusion of MOVK+MOVK:
Implements fusion of MOVK+MOVK instructions as used when
synthesising immediates.
- [4/5] Implement fusion of ARDP+LDR:
Implements fusion of ADRP+LDR instructions when the appropriate
register constraints are met.
- [5/5] Add macro fusion support for cmp/b.X for ThunderX:
This is a rebase of Andrews' patch on top of the previous four
and implements fusion of flag-setting instructions together
with a conditional branch.
These have been bootstrapped and tested on aarch64-none-linux-gnu.
Ok for trunk?
Thanks,
Kyrill
