If we have two (or more) smooth varyings like this: nop t3; ldvary.rf0 fmul t5, t3, t0 fadd t6, t5, r5 nop t7; ldvary.rf0 fmul t9, t7, t0 fadd t10, t9, r5 nop t11; ldvary.rf0 fmul t13, t11, t0 fadd t14, t13, r5 We may be able to pipeline them like this: nop ; nop ; ldvary.r4 nop ; fmul r0, r4, rf0 ; ldvary.r1 fadd rf13, r0, r5 ; fmul r2, r1, rf0 ; ldvary.r3 fadd rf12, r2, r5 ; fmul r4, r3, rf0 ; ldvary.r0 But in order to do this, we will need to manually tweak the QPU scheduling. This patch tracks information about ldvary sequences that are good candidates for pipelining, and a follow-up patch will use this information to pipeline them when we emit the QPU code. v2 (apinheiro): - Rename the v3d_compile fields to avoid confusion with the qinst fields. - Assert that a sequence's start instruction is not the same as the end.
