Commit Message

Stefan Schulze Frielinghaus Sept. 19, 2024, 2:05 p.m. UTC 
I have been missing the two test cases and removed them since they
depend on -mno-lra.

-- 8< --

Since the old reload pass is about to be removed and we defaulted to LRA
for over a decade, remove option -m{,no-}lra.

PR target/113953

gcc/ChangeLog:

	* config/s390/s390.cc (s390_lra_p): Remove.
	(TARGET_LRA_P): Remove.
	* config/s390/s390.opt (mlra): Remove.
	* config/s390/s390.opt.urls (mlra): Remove.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/TI-constants-nolra.c: Removed.
	* gcc.target/s390/pr79895.c: Removed.

Can't approve but it looks right. Thanks for handling it, especially so quickly!
