Hello! I'd like to backport two LRA patches to gcc-14 branch:
1. [PR114942][LRA]: Don't reuse input reload reg of inout early clobber operand https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=9585317f0715699197b1313bbf939c6ea3c1ace6 2. [PR117105][LRA]: Use unique value reload pseudo for early clobber operand https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=4b09e2c67ef593db171b0755b46378964421782b They both fix RA failure with strict_low_part family of instructions: (insn 24 55 54 4 (parallel [ (set (strict_low_part (reg:QI 2 cx [orig:109 e ] [109])) (and:QI (subreg:QI (zero_extract:HI (reg/v:HI 2 cx [orig:109 e ] [109]) (const_int 8 [0x8]) (const_int 8 [0x8])) 0) (reg:QI 1 dx [orig:115 _6 ] [115]))) (clobber (reg:CC 17 flags)) that were added by me for PR target/78904, so I have some interest in the backport. The backport of two patches was bootstrapped and regression tested with the current gcc-14 branch. Is the backport OK for branch? Thanks, Uros.
