From: Michal Krol Date: Wed, 4 Nov 2009 11:47:10 +0000 (+0000) Subject: tgsi/ureg: Allow for multiple extended instruction tokens. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=767bc8eb5a0bbaf9fde9d760e8460d34c51d2991;p=mesa.git tgsi/ureg: Allow for multiple extended instruction tokens. For example, we would like to have a predicate and texture token in one instruction to do predicated texture sampling. --- diff --git a/src/gallium/auxiliary/tgsi/tgsi_ureg.c b/src/gallium/auxiliary/tgsi/tgsi_ureg.c index 67af953e099..4731e3bde84 100644 --- a/src/gallium/auxiliary/tgsi/tgsi_ureg.c +++ b/src/gallium/auxiliary/tgsi/tgsi_ureg.c @@ -644,7 +644,7 @@ static void validate( unsigned opcode, #endif } -unsigned +struct ureg_emit_insn_result ureg_emit_insn(struct ureg_program *ureg, unsigned opcode, boolean saturate, @@ -659,6 +659,7 @@ ureg_emit_insn(struct ureg_program *ureg, { union tgsi_any_token *out;
