v_cmpsx_nle_f32 GPU Native ISA AMD Vector
Comparison
AMDGPU VOPC vector instruction operating on f32 data. (Format and name extracted from LLVM's AMDGPU backend source - semantics not yet curated.)
Encoding
Operands
-
1: special register
Architectural register rather than a general-purpose one. Written vcc in the assembler example. -
2: immediate
Literal value encoded in the instruction. Written 0 in the assembler example. -
3: VGPR
Vector general-purpose register, one value per lane. Written v2 in the assembler example.
Register classes read from the LLVM assembler example on this page. No source this site uses names these operands, so no names are given.
GFX Target Compatibility
Per-target GFX compatibility has not yet been verified for this instruction.
