From: Pan Li <pan2...@intel.com> This patch would like to introduce the combine of vec_dup + vmerge.vvm into vmerge.vxm on the cost value of GR2VR. The late-combine will take place if the cost of GR2VR is zero, or reject the combine if non-zero like 1, 2, 15 in test. From: | ... | vmv.v.x | L1: | vaadd.vv | J L1 | ... To: | ... | L1: | vmerge.vxm | J L1 | ... The below test suites are passed for this patch series. * The rv64gcv fully regression test. Pan Li (2): RISC-V: Combine vec_duplicate + vmerge.vv to vmerge.vx on GR2VR cost RISC-V: RISC-V: Add test for vec_duplicate + vmerge.vvm combine with GR2VR cost 0, 1 and 15
This series is OK. Thanks, Jeff
