From f37b114dc3b9281938738572246fe7c685cf7211 Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Mon, 18 Oct 2010 09:35:21 -0700 Subject: llvmpipe: Don't test rounding of x.5 numbers. SSE4.1 has different rules, and so far this doesn't seem to cause any problems with conformance test suites. --- src/gallium/drivers/llvmpipe/lp_test_round.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/gallium/drivers/llvmpipe') diff --git a/src/gallium/drivers/llvmpipe/lp_test_round.c b/src/gallium/drivers/llvmpipe/lp_test_round.c index 0ca2791592..816518e508 100644 --- a/src/gallium/drivers/llvmpipe/lp_test_round.c +++ b/src/gallium/drivers/llvmpipe/lp_test_round.c @@ -171,9 +171,12 @@ test_round(unsigned verbose, FILE *fp) LLVMDumpModule(module); for (i = 0; i < 3; i++) { + /* NOTE: There are several acceptable rules for x.5 rounding: ceiling, + * nearest even, etc. So we avoid testing such corner cases here. + */ v4sf xvals[3] = { {-10.0, -1, 0, 12.0}, - {-1.5, -0.25, 1.25, 2.5}, + {-1.49, -0.25, 1.25, 2.51}, {-0.99, -0.01, 0.01, 0.99} }; v4sf x = xvals[i]; -- cgit v1.2.3
