This patch series allows qemu to utilize LSX instructions on LoongArch machines to execute TCG vector ops.
Passed tcg tests with x86_64 and aarch64 cross compilers. Changes since v3: - Refactor add/sub_vec handling code to use a helper function - Only use vldx/vstx for MO_128 load/store, otherwise fallback to two ld/st Changes since v2: - Add vece argument to tcg_target_const_match() for const args of vector ops - Use custom constraint for cmp_vec/add_vec/sub_vec for better const arg handling - Implement 128-bit load & store using vldx/vstx Changes since v1: - Optimize dupi_vec/st_vec/ld_vec/cmp_vec/add_vec/sub_vec generation - Lower not_vec/shi_vec/roti_vec/rotv_vec Jiajie Chen (16): tcg/loongarch64: Import LSX instructions tcg/loongarch64: Lower basic tcg vec ops to LSX tcg: pass vece to tcg_target_const_match() tcg/loongarch64: Lower cmp_vec to vseq/vsle/vslt tcg/loongarch64: Lower add/sub_vec to vadd/vsub tcg/loongarch64: Lower vector bitwise operations tcg/loongarch64: Lower neg_vec to vneg tcg/loongarch64: Lower mul_vec to vmul tcg/loongarch64: Lower vector min max ops tcg/loongarch64: Lower vector saturated ops tcg/loongarch64: Lower vector shift vector ops tcg/loongarch64: Lower bitsel_vec to vbitsel tcg/loongarch64: Lower vector shift integer ops tcg/loongarch64: Lower rotv_vec ops to LSX tcg/loongarch64: Lower rotli_vec to vrotri tcg/loongarch64: Implement 128-bit load & store tcg/aarch64/tcg-target.c.inc | 2 +- tcg/arm/tcg-target.c.inc | 2 +- tcg/i386/tcg-target.c.inc | 2 +- tcg/loongarch64/tcg-insn-defs.c.inc | 6251 +++++++++++++++++++++++++- tcg/loongarch64/tcg-target-con-set.h | 9 + tcg/loongarch64/tcg-target-con-str.h | 3 + tcg/loongarch64/tcg-target.c.inc | 619 ++- tcg/loongarch64/tcg-target.h | 40 +- tcg/loongarch64/tcg-target.opc.h | 12 + tcg/mips/tcg-target.c.inc | 2 +- tcg/ppc/tcg-target.c.inc | 2 +- tcg/riscv/tcg-target.c.inc | 2 +- tcg/s390x/tcg-target.c.inc | 2 +- tcg/sparc64/tcg-target.c.inc | 2 +- tcg/tcg.c | 4 +- tcg/tci/tcg-target.c.inc | 2 +- 16 files changed, 6824 insertions(+), 132 deletions(-) create mode 100644 tcg/loongarch64/tcg-target.opc.h -- 2.42.0
