Subject: tcg/loongarch64: Support LASX in tcg_out_dupm_vec
X-Git-Tag: v9.1.0-rc0~65^2~16
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=15750faa8ecd070cbc01bbd22db8c7a2b7e410e5;p=thirdparty%2Fqemu.git

tcg/loongarch64: Support LASX in tcg_out_dupm_vec

Each element size has a different encoding, so code cannot
be shared in the same way as with tcg_out_dup_vec.
