X-Git-Tag: basepoints/gcc-16~6829
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7268d7249b3ca31bf322de99b1d59baf06f83eb3;p=thirdparty%2Fgcc.git

AArch64: Set instruction attribute of TST to logics_imm

As suggested in
https://gcc.gnu.org/pipermail/gcc-patches/2024-July/658249.html,
this patch changes the instruction attribute of "*and<mode>_compare0" (TST) from
alus_imm to logics_imm.

The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
