Set default sched pressure algorithm
The Arm backend sets the default sched-pressure algorithm to SCHED_PRESSURE_MODEL.
Benchmarking on AArch64 shows this speeds up floating point performance on SPEC -
eg. CactusBSSN improves by ~16%. The gains are mostly due to less spilling,
so enable this on AArch64 by default.
gcc/
* config/aarch64/aarch64.c (aarch64_override_options_internal):
Set PARAM_SCHED_PRESSURE_ALGORITHM to SCHED_PRESSURE_MODEL.
