Subject: intel/compiler: split float to 64-bit opcodes from int to 64-bit
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=92f4761198d24fb73cbe5bcd12b0ebf5bb766b4d;p=mesa.git

intel/compiler: split float to 64-bit opcodes from int to 64-bit

Going forward having these split is a bit more convenient since these two
groups have different restrictions.

v2:
 - Rebased on top of new regioning lowering pass.
