--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jiu Fu Guo <guoji...@gcc.gnu.org>: https://gcc.gnu.org/g:5eb7d560626e427673c53723ed430c4bb5721f33 commit r14-923-g5eb7d560626e427673c53723ed430c4bb5721f33 Author: Jiufu Guo <guoji...@linux.ibm.com> Date: Sat Dec 10 21:18:51 2022 +0800 rs6000: use lis;xoris to build constant For constant C: If '(c & 0xFFFFFFFF0000FFFFULL) == 0xFFFFFFFF00000000' or say: 32(1) || 1(0) || 15(x) || 16(0), we could use "lis; xoris" to build. Here N(M) means N continuous bit M, x for M means it is ok for either 1 or 0; '||' means concatenation. This patch update rs6000_emit_set_long_const to support those constants. Compare with previous version: https://gcc.gnu.org/pipermail/gcc-patches/2022-December/608292.html This patch updates test function names only. Bootstrap and regtest pass on ppc64{,le}. PR target/106708 gcc/ChangeLog: * config/rs6000/rs6000.cc (rs6000_emit_set_long_const): Support building constants through "lis; xoris". gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr106708.c: Add test function.
