The old version worked by precoloring both the operand and definition to whatever register the operand was at the time. This didn't allow moving the operand/definition after precoloring them, or two tied operands with the same temporary. The new version works by temporarily making the operands late kill and creating a copy if the temporary is live-through or used as another tied operand. Then we can simply later make the operands early kill again and assign the definitions to the operand's register. This way, we can move the operand to make space and the new location will not intersect with any other definition and won't cause the operand and definition registers to mismatch. fossil-db (gfx1201): Totals from 2253 (2.84% of 79377) affected shaders: Instrs: 1634747 -> 1630799 (-0.24%); split: -0.27%, +0.03% CodeSize: 8688148 -> 8672348 (-0.18%); split: -0.20%, +0.02% VGPRs: 106500 -> 106512 (+0.01%) Latency: 11385480 -> 11382965 (-0.02%); split: -0.04%, +0.01% InvThroughput: 1754430 -> 1754326 (-0.01%); split: -0.01%, +0.00% SClause: 38954 -> 38964 (+0.03%); split: -0.01%, +0.04% Copies: 110772 -> 110800 (+0.03%); split: -0.02%, +0.04% Branches: 29093 -> 29092 (-0.00%) VALU: 902011 -> 902008 (-0.00%) SALU: 260175 -> 260203 (+0.01%); split: -0.01%, +0.02% fossil-db (navi31): Totals from 2 (0.00% of 79377) affected shaders: Latency: 1766 -> 1765 (-0.06%) InvThroughput: 3219 -> 3215 (-0.12%) fossil-db (navi21): Totals from 14 (0.02% of 79377) affected shaders: (no affected stats) Signed-off-by: Rhys Perry <pendingchaos02@gmail.com> Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34700>
