LoongArch: Enable shrink wrapping
This commit implements the target macros for shrink wrapping of function
prologues/epilogues shrink wrapping on LoongArch.
Bootstrapped and regtested on loongarch64-linux-gnu. I don't have an
access to SPEC CPU so I hope the reviewer can perform a benchmark to see
if there is real benefit.
gcc/ChangeLog:
* config/loongarch/loongarch.h (struct machine_function): Add
reg_is_wrapped_separately array for register wrapping
information.
* config/loongarch/loongarch.cc
(loongarch_get_separate_components): New function.
(loongarch_components_for_bb): Likewise.
(loongarch_disqualify_components): Likewise.
(loongarch_process_components): Likewise.
(loongarch_emit_prologue_components): Likewise.
(loongarch_emit_epilogue_components): Likewise.
(loongarch_set_handled_components): Likewise.
(TARGET_SHRINK_WRAP_GET_SEPARATE_COMPONENTS): Define.
(TARGET_SHRINK_WRAP_COMPONENTS_FOR_BB): Likewise.
(TARGET_SHRINK_WRAP_DISQUALIFY_COMPONENTS): Likewise.
(TARGET_SHRINK_WRAP_EMIT_PROLOGUE_COMPONENTS): Likewise.
(TARGET_SHRINK_WRAP_EMIT_EPILOGUE_COMPONENTS): Likewise.
(TARGET_SHRINK_WRAP_SET_HANDLED_COMPONENTS): Likewise.
(loongarch_for_each_saved_reg): Skip registers that are wrapped
separately.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/shrink-wrap.c: New test.
