From 21190fbd56ec2f12dc5a1bf1d9fc32d507e8f0a3 Mon Sep 17 00:00:00 2001 From: Christian König Date: Thu, 7 Mar 2013 15:02:31 +0100 Subject: tgsi: use separate structure for indirect address v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To further improve the optimization of source and destination indirect addressing we need the ability to store a reference to the declaration of the addressed operands. Since most of the fields in tgsi_src_register doesn't apply for an indirect addressing operand replace it with a separate tgsi_ind_register structure and so make room for extra information. v2: rename Declaration to ArrayID, put the ArrayID into () instead of [] Signed-off-by: Christian König --- src/gallium/auxiliary/tgsi/tgsi_build.c | 109 ++++++++++++++++++-------------- src/gallium/auxiliary/tgsi/tgsi_dump.c | 28 ++++++-- src/gallium/auxiliary/tgsi/tgsi_exec.c | 8 +-- src/gallium/auxiliary/tgsi/tgsi_parse.c | 35 ++-------- src/gallium/auxiliary/tgsi/tgsi_parse.h | 8 +-- src/gallium/auxiliary/tgsi/tgsi_text.c | 27 +++++--- src/gallium/auxiliary/tgsi/tgsi_ureg.c | 36 +++++------ src/gallium/auxiliary/tgsi/tgsi_ureg.h | 7 ++ src/gallium/auxiliary/tgsi/tgsi_util.c | 18 ++++++ src/gallium/auxiliary/tgsi/tgsi_util.h | 3 + 10 files changed, 161 insertions(+), 118 deletions(-) (limited to 'src/gallium/auxiliary/tgsi') diff --git a/src/gallium/auxiliary/tgsi/tgsi_build.c b/src/gallium/auxiliary/tgsi/tgsi_build.c index 33cbbd8ca65..435d94a2103 100644 --- a/src/gallium/auxiliary/tgsi/tgsi_build.c +++ b/src/gallium/auxiliary/tgsi/tgsi_build.c @@ -816,6 +816,43 @@ tgsi_build_src_register( return src_register;
