This is an update of: https://gcc.gnu.org/pipermail/gcc-patches/2023-August/627413.html
Changes since last version of patch set: - Fix regression test fail of pr54346.c with RUNTESTFLAGS="--target_board=unix/-mlsx". This is caused by the code simplification of loongarch_expand_vec_perm_const_2 () in last version. - Combine vilvh/xvilvh insn's RTL template impl. - Add dg-skip-if for loongarch*-*-* in vshuf test in g++.dg/torture, because vshuf/xvshuf insn's result is undefined when 6 or 7 bit of vector's element is set, and insns with this condition are generated in these testcases. Brief version 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.
