Hi,
Following up the discussion of V2 patches in
https://gcc.gnu.org/pipermail/gcc-patches/2023-December/639368.html,
this patch series add early clobber for all TImode NDD alternatives
to avoid any potential overlapping between dest register and src
register/memory. Also use get_attr_isa (insn) == ISA_APX_NDD instead of
checking alternative at asm output stage.
Bootstrapped & regtested on x86_64-pc-linux-gnu{-m32,} and sde.
Ok for master?
