[Mesa-dev] Removing unused opcodes (TGSI, Mesa IR)

[Jose Fonseca]

It looks like ARR is generated, as src/gallium/state_trackers/nine/nine_shader.c has

#define _OPI(o,t,vv1,vv2,pv1,pv2,d,s,h) \
    { D3DSIO_##o, TGSI_OPCODE_##t, { vv1, vv2 }, { pv1, pv2, }, d, s, h }

[...]

  _OPI(MOVA, ARR, V(2,0), V(3,0), V(0,0), V(0,0), 1, 1, NULL),


Jose

They've got code for lowering NRM and CND to sanity, and no use of ARR,
ARA, X2D, RFL, STR, SFL, or BRA.
