Author: Eric Anholt <[email protected]> Date: Wed Feb 6 13:17:21 2019 -0800 v3d: Use the NIR lowering for isign instead of rolling our own. min/max instead of comparisons saves 2 instructions on fs-sign-int.shader_test. --- src/broadcom/compiler/nir_to_vir.c | 17 +---------------- 1 file changed, 1 insertion(+), 16 deletions(-) diff --git a/src/broadcom/compiler/nir_to_vir.c b/src/broadcom/compiler/nir_to_vir.c index d983f91e71..41fc03aa24 100644 --- a/src/broadcom/compiler/nir_to_vir.c +++ b/src/broadcom/compiler/nir_to_vir.c @@ -547,19 +547,6 @@ ntq_fsign(struct v3d_compile *c, struct qreg src) return vir_MOV(c, t); } -static struct qreg -ntq_isign(struct v3d_compile *c, struct qreg src) -{ - struct qreg t = vir_get_temp(c); - - vir_MOV_dest(c, t, vir_uniform_ui(c, 0)); - vir_PF(c, vir_MOV(c, src), V3D_QPU_PF_PUSHZ); - vir_MOV_cond(c, V3D_QPU_COND_IFNA, t, vir_uniform_ui(c, 1)); - vir_PF(c, vir_MOV(c, src), V3D_QPU_PF_PUSHN); - vir_MOV_cond(c, V3D_QPU_COND_IFA, t, vir_uniform_ui(c, -1)); - return vir_MOV(c, t); -} - static void emit_fragcoord_input(struct v3d_compile *c, int attr) { @@ -1025,9 +1012,6 @@ ntq_emit_alu(struct v3d_compile *c, nir_alu_instr *instr) case nir_op_fsign: result = ntq_fsign(c, src[0]); break; - case nir_op_isign: - result = ntq_isign(c, src[0]); - break; case nir_op_fabs: { result = vir_FMOV(c, src[0]); @@ -2476,6 +2460,7 @@ const nir_shader_compiler_options v3d_nir_options = { .lower_fsat = true, .lower_fsqrt = true, .lower_ifind_msb = true, + .lower_isign = true, .lower_ldexp = true, .lower_mul_high = true, .lower_wpos_pntc = true, _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
