From f920f8eb026d39c0adb547a90399e76b8351fec6 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 8 Dec 2015 21:01:15 -0500 Subject: [PATCH] nv50/ir: fix cutoff for using r63 vs r127 when replacing zero The only effect here is a space savings - 822 programs in shader-db affected with the following overall change: total bytes used in shared programs : 44154976 -> 44139880 (-0.03%) Fixes: 641eda0c (nv50/ir: r63 is only 0 if we are using less than 63 registers) Signed-off-by: Ilia Mirkin Cc: "11.0 11.1" --- src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nv50.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nv50.cpp b/src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nv50.cpp index df44a7be7b7..64f5fc0031e 100644 --- a/src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nv50.cpp +++ b/src/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nv50.cpp @@ -202,7 +202,8 @@ NV50LegalizePostRA::visit(Function *fn) Program *prog = fn->getProgram(); r63 = new_LValue(fn, FILE_GPR); - if (prog->maxGPR < 63) + // GPR units on nv50 are in half-regs + if (prog->maxGPR < 126) r63->reg.data.id = 63; else r63->reg.data.id = 127; -- 2.30.2
