I don't know why the float_saturate_l_mov test was #if'ed out, but it
passes... so this commit enables it.
No shader-db or fossil-db changes.
In a previous iteration of this MR, this commit helped ~200 shaders in
shader-db. Now all of those same shaders are helped by "intel/fs: cmod
propagate from MOV with any condition". All of these shaders come from
Mad Max. After initial translation from NIR to assembly, these shader
contain patterns like:
mul(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.sat(8) g90<1>F g90<8,8,1>F
...
cmp.nz.f0(8) null<1>F g90<8,8,1>F 0 /* 0F */
An initial pass of cmod propagation converts this to
mul(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.sat.XX.f0(8) g90<1>F g90<8,8,1>F
Without this commit, XX is G. With this commit, XX is NZ. Saturate
propagation moves the saturate:
mul.sat(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
...
mov.XX.f0(8) g90<1>F g90<8,8,1>F
Without this commit (but with "intel/fs: cmod propagate from MOV with
any condition"), the G gets propagated:
mul.sat.g.f0(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
With this commit (with or without "intel/fs: cmod propagate from MOV
with any condition"), the NZ gets propagated:
mul.sat.nz.f0(8) g90<1>F g88<8,8,1>F 0x40400000F /* 3F */
