From 11f41f54cf4ce1cdc19c4b5c45ed8d2083d96831 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Sat, 12 Sep 2009 14:18:50 -0700 Subject: [PATCH] ureg: add a mechanism to get the built tokens rather than a full shader Previously ureg would always call the driver's create-shader function. This allows the caller the opportunity to hold onto the tokens if it needs to reuse them, eg. to create an internal draw shader. --- src/gallium/auxiliary/tgsi/tgsi_ureg.c | 19 +++++++++++++++++++ src/gallium/auxiliary/tgsi/tgsi_ureg.h | 11 +++++++++++ 2 files changed, 30 insertions(+) diff --git a/src/gallium/auxiliary/tgsi/tgsi_ureg.c b/src/gallium/auxiliary/tgsi/tgsi_ureg.c index 352cb5a1e32..9e2e7f0d19b 100644 --- a/src/gallium/auxiliary/tgsi/tgsi_ureg.c +++ b/src/gallium/auxiliary/tgsi/tgsi_ureg.c @@ -978,6 +978,25 @@ void *ureg_create_shader( struct ureg_program *ureg, } +const struct tgsi_token *ureg_get_tokens( struct ureg_program *ureg, + unsigned *nr_tokens ) +{ + const struct tgsi_token *tokens; + + ureg_finalize(ureg); + + tokens = &ureg->domain[DOMAIN_DECL].tokens[0].token; + + if (nr_tokens) + *nr_tokens = ureg->domain[DOMAIN_DECL].size; + + ureg->domain[DOMAIN_DECL].tokens = 0; + ureg->domain[DOMAIN_DECL].size = 0; + ureg->domain[DOMAIN_DECL].order = 0; + ureg->domain[DOMAIN_DECL].count = 0; + + return tokens; +} struct ureg_program *ureg_create( unsigned processor ) diff --git a/src/gallium/auxiliary/tgsi/tgsi_ureg.h b/src/gallium/auxiliary/tgsi/tgsi_ureg.h index 48aeaaf459d..f04f443b9e7 100644 --- a/src/gallium/auxiliary/tgsi/tgsi_ureg.h +++ b/src/gallium/auxiliary/tgsi/tgsi_ureg.h @@ -82,10 +82,21 @@ ureg_create( unsigned processor ); const struct tgsi_token * ureg_finalize( struct ureg_program * ); +/* Create and return a shader: + */ void * ureg_create_shader( struct ureg_program *, struct pipe_context *pipe ); + +/* Alternately, return the built token stream and hand ownership of + * that memory to the caller: + */ +const struct tgsi_token * +ureg_get_tokens( struct ureg_program *ureg, + unsigned *nr_tokens ); + + void ureg_destroy( struct ureg_program * ); -- 2.30.2
