about
nx_dxbc_real_gate.nx -- HEAVY VET (MSU discipline): grade our DXBC decoder against a REAL fxc-compiled shader, not
our own fixture. Ground truth = Microsoft fxc /Fc disassembly of ps_5_0 (knowledge/real_shader.cso, 760B, 5 chunks):
7 declarations (dcl_globalFlags/sampler/resource_texture2d/input_ps x2/output/temps) + sample + mad + mov + ret,
ZERO dp3 (the optimizer folded dot(n,(0,0,1)) -> .zzzz). program type = 0 (pixel).
If our opcode numbers / container walk are wrong, THIS is what catches it (a self-gate cannot). license_tier: ORIGINAL expect_exit: 0
