Michael Krumland-DunningandClaude Opus 5.5 952cc18efa test(shader): pin SDWA v_cvt_f32_ubyte source selects measured on RDNA2
v_cvt_f32_ubyte0 to v_cvt_f32_ubyte3 take byte N of source 0 after
SRC0_SEL and SRC0_SEXT select and extend it, as measured with the
hardware oracle on RDNA2 (gfx1036) for all seven source selects with
and without SRC0_SEXT. The test checked four combinations derived from
the ISA guide; it now checks every combination against the measured
results, and the debt entry keeps only what is not measured: gfx1013.
