This is an update of: https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628303.html
Changes since last version of patch set: - "dg-skip-if"-related Changes of the g++.dg/torture/vshuf* testcases are reverted. (Replaced by __builtin_shuffle fix) - Add fix of __builtin_shuffle() for Loongson SX/ASX (Implemeted by adding vand/xvand insn in front of shuffle operation). There's no significant performance impact in current state. - Rebased on the top of Yang Yujie's latest target configuration interface patch set (https://gcc.gnu.org/pipermail/gcc-patches/2023-August/628772.html). Brief history of patch set: v1 -> v2: - Reduce usage of "unspec" in RTL template. - Append Support of ADDR_REG_REG in LSX and LASX. - Constraint docs are appended in gcc/doc/md.texi and ccomment block. - Codes related to vecarg are removed. - Testsuite of LSX and LASX is added in v2. (Because of the size limitation of mail list, these patches are not shown) - Adjust the loongarch_expand_vector_init() function to reduce instruction output amount. - Some minor implementation changes of RTL templates. v2 -> v3: - Revert vabsd/xvabsd RTL templates to unspec impl. - Resolve warning in gcc/config/loongarch/loongarch.cc when bootstrapping with BOOT_CFLAGS="-O2 -ftree-vectorize -fno-vect-cost-model -mlasx". - Remove redundant definitions in lasxintrin.h. - Refine commit info. v3 -> v4: - Code simplification. - Testsuite patches are splited from this patch set again and will be submitted independently in the future. v4 -> v5: - Regression test fix (pr54346.c) - Combine vilvh/xvilvh insn's RTL template impl. - Add dg-skip-if for loongarch*-*-* in vshuf test inside g++.dg/torture (reverted in this version) Lulu Cheng (4): LoongArch: Add Loongson SX base instruction support. LoongArch: Add Loongson SX directive builtin function support. LoongArch: Add Loongson ASX base instruction support.
