From: Kewen Lin <linkw@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r14-240] rs6000: Guard power9-vector for vsx_scalar_cmp_exp_qp_* [PR108758] Date: Wed, 26 Apr 2023 05:22:27 +0000 (GMT) [thread overview] Message-ID: <20230426052227.A4EB53858C60@sourceware.org> (raw) https://gcc.gnu.org/g:33a44e3aa81f9fdf8f6b87018abd4c664e545b53 commit r14-240-g33a44e3aa81f9fdf8f6b87018abd4c664e545b53 Author: Kewen Lin <linkw@linux.ibm.com> Date: Wed Apr 26 00:21:14 2023 -0500 rs6000: Guard power9-vector for vsx_scalar_cmp_exp_qp_* [PR108758] __builtin_vsx_scalar_cmp_exp_qp_{eq,gt,lt,unordered} used to be guarded with condition TARGET_P9_VECTOR before new bif framework was introduced (r12-5752-gd08236359eb229), since r12-5752 they are placed under stanza ieee128-hw, that is to check condition TARGET_FLOAT128_HW, it caused test case float128-cmp2-runnable.c to fail at -m32 as the condition TARGET_FLOAT128_HW isn't satisified with -m32. By checking the commit history, I didn't see any notes on why this condition change on them was made, so this patch is to move these bifs from stanza ieee128-hw to stanza power9-vector as before. PR target/108758 gcc/ChangeLog: * config/rs6000/rs6000-builtins.def (__builtin_vsx_scalar_cmp_exp_qp_eq, __builtin_vsx_scalar_cmp_exp_qp_gt __builtin_vsx_scalar_cmp_exp_qp_lt, __builtin_vsx_scalar_cmp_exp_qp_unordered): Move from stanza ieee128-hw to power9-vector.
