From d3cdbf6fd817ae5e7a8a72bcc3f43cc1b04a709b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 8 Jul 2016 15:24:34 -0700 Subject: vc4: Add a "qir_for_each_inst_inorder" macro and use it in many places. We have the prior list_foreach() all over the code, but I need to move where instructions live as part of adding support for control flow. Start by just converting to a helper iterator macro. (The simpler "qir_for_each_inst()" will be used for the for-each-inst-in-a-block iterator macro later) --- src/gallium/drivers/vc4/vc4_opt_algebraic.c | 2 +- src/gallium/drivers/vc4/vc4_opt_constant_folding.c | 2 +- src/gallium/drivers/vc4/vc4_opt_copy_propagation.c | 2 +- src/gallium/drivers/vc4/vc4_opt_small_immediates.c | 2 +- src/gallium/drivers/vc4/vc4_opt_vpm.c | 4 ++-- src/gallium/drivers/vc4/vc4_program.c | 2 +- src/gallium/drivers/vc4/vc4_qir.h | 3 +++ src/gallium/drivers/vc4/vc4_qir_lower_uniforms.c | 4 ++-- src/gallium/drivers/vc4/vc4_qir_validate.c | 2 +- src/gallium/drivers/vc4/vc4_qpu_emit.c | 2 +- src/gallium/drivers/vc4/vc4_register_allocate.c | 4 ++-- src/gallium/drivers/vc4/vc4_reorder_uniforms.c | 2 +- 12 files changed, 17 insertions(+), 14 deletions(-) (limited to 'src') diff --git a/src/gallium/drivers/vc4/vc4_opt_algebraic.c b/src/gallium/drivers/vc4/vc4_opt_algebraic.c index b8ce377ff6b..01ad05d2759 100644 --- a/src/gallium/drivers/vc4/vc4_opt_algebraic.c +++ b/src/gallium/drivers/vc4/vc4_opt_algebraic.c @@ -143,7 +143,7 @@ qir_opt_algebraic(struct vc4_compile *c) { bool progress = false;
