From e8d6b2793ff3907d3646eeaceaa00e2a04728e67 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 5 Nov 2010 08:49:53 -0600 Subject: [PATCH] gallivm: alloca() was called too often for temporary arrays Need to increment the array index to point to the last value. Before, we were calling lp_build_array_alloca() over and over for no reason. --- src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c b/src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c index a74cefd..897b09f 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c +++ b/src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c @@ -1189,10 +1189,12 @@ emit_declaration( case TGSI_FILE_TEMPORARY: assert(idx < LP_MAX_TGSI_TEMPS); if (bld->indirect_files & (1 << TGSI_FILE_TEMPORARY)) { + /* ignore 'first' - we want to index into a 0-based array */ LLVMValueRef array_size = LLVMConstInt(LLVMInt32Type(), last*4 + 4, 0); bld->temps_array = lp_build_array_alloca(bld->base.builder, vec_type, array_size, "temparray"); + idx = last; } else { for (i = 0; i < NUM_CHANNELS; i++) bld->temps[idx][i] = lp_build_alloca(bld->base.builder, -- 2.7.4
