From 84a304eb96ec36df32d939385d51fb8e2026472c Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 24 Feb 2017 12:00:38 -0800 Subject: [PATCH] vc4: Track the last block we emitted at the top level. This will be used for delaying our VPM reads (which must be unconditional) until just before they're used. --- src/gallium/drivers/vc4/vc4_program.c | 13 ++++++++----- src/gallium/drivers/vc4/vc4_qir.c | 1 + src/gallium/drivers/vc4/vc4_qir.h | 1 + 3 files changed, 10 insertions(+), 5 deletions(-) diff --git a/src/gallium/drivers/vc4/vc4_program.c b/src/gallium/drivers/vc4/vc4_program.c index e6131708c1f..164257ec763 100644 --- a/src/gallium/drivers/vc4/vc4_program.c +++ b/src/gallium/drivers/vc4/vc4_program.c @@ -1956,11 +1956,12 @@ ntq_emit_if(struct vc4_compile *c, nir_if *if_stmt) qir_link_blocks(c->cur_block, after_block); qir_set_emit_block(c, after_block); - if (was_top_level) + if (was_top_level) { c->execute = c->undef; - else + c->last_top_block = c->cur_block; + } else { ntq_activate_execute_for_block(c); - + } } static void @@ -2084,10 +2085,12 @@ ntq_emit_loop(struct vc4_compile *c, nir_loop *loop) qir_link_blocks(c->cur_block, c->loop_break_block); qir_set_emit_block(c, c->loop_break_block); - if (was_top_level) + if (was_top_level) { c->execute = c->undef; - else + c->last_top_block = c->cur_block; + } else { ntq_activate_execute_for_block(c); + } c->loop_break_block = save_loop_break_block; c->loop_cont_block = save_loop_cont_block; diff --git a/src/gallium/drivers/vc4/vc4_qir.c b/src/gallium/drivers/vc4/vc4_qir.c index ed76c64ba9c..c829e7f93b7 100644 --- a/src/gallium/drivers/vc4/vc4_qir.c +++ b/src/gallium/drivers/vc4/vc4_qir.c @@ -646,6 +646,7 @@ qir_compile_init(void) list_inithead(&c->blocks); qir_set_emit_block(c, qir_new_block(c)); + c->last_top_block = c->cur_block; c->output_position_index = -1; c->output_color_index = -1; diff --git a/src/gallium/drivers/vc4/vc4_qir.h b/src/gallium/drivers/vc4/vc4_qir.h index daeb52b9aee..6469e51b051 100644 --- a/src/gallium/drivers/vc4/vc4_qir.h +++ b/src/gallium/drivers/vc4/vc4_qir.h @@ -506,6 +506,7 @@ struct vc4_compile { struct qblock *cur_block; struct qblock *loop_cont_block; struct qblock *loop_break_block; + struct qblock *last_top_block; struct list_head qpu_inst_list; -- 2.30.2
