From f6f547d87ea68f44c50a0b0231b7360ca94b2975 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 9 Mar 2010 09:56:42 -0800 Subject: [PATCH] i965: Fix nested loops in the VS. We were patching up all the break and continues between the start of our loop and the end of our loop, even if they were breaks/continues for an inner loop. Avoiding patching already patched breaks/continues fixes piglit glsl-vs-loop-nested. --- src/mesa/drivers/dri/i965/brw_vs_emit.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_vs_emit.c b/src/mesa/drivers/dri/i965/brw_vs_emit.c index a7c4b58..a48804a 100644 --- a/src/mesa/drivers/dri/i965/brw_vs_emit.c +++ b/src/mesa/drivers/dri/i965/brw_vs_emit.c @@ -1717,11 +1717,13 @@ void brw_vs_emit(struct brw_vs_compile *c ) /* patch all the BREAK/CONT instructions from last BEGINLOOP */ while (inst0 > loop_inst[loop_depth]) { inst0--; - if (inst0->header.opcode == BRW_OPCODE_BREAK) { + if (inst0->header.opcode == BRW_OPCODE_BREAK && + inst0->bits3.if_else.jump_count == 0) { inst0->bits3.if_else.jump_count = br * (inst1 - inst0 + 1); inst0->bits3.if_else.pop_count = 0; } - else if (inst0->header.opcode == BRW_OPCODE_CONTINUE) { + else if (inst0->header.opcode == BRW_OPCODE_CONTINUE && + inst0->bits3.if_else.jump_count == 0) { inst0->bits3.if_else.jump_count = br * (inst1 - inst0); inst0->bits3.if_else.pop_count = 0; } -- 2.7.4
