Semantics
declare tmp : 32'B;
tmp[15 : 0].i16 = S0[15 : 0].i16 < S1[15 : 0].i16 ? S0[15 : 0].i16 : S1[15 : 0].i16;
tmp[31 : 16].i16 = S0[31 : 16].i16 < S1[31 : 16].i16 ? S0[31 : 16].i16 : S1[31 : 16].i16;
D0.b32 = tmp
Example
v_pk_min_i16 v5, s1, s2A real instruction accepted by the LLVM assembler, taken verbatim from LLVM's own AMDGPU MC test suite (gfx11). Not from an AMD document, and not authored here.
