From: Carl Worth Date: Thu, 14 Apr 2011 21:35:11 +0000 (-0700) Subject: Add an expected file for 094-divide-by-zero-short-circuit X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d3c6ed382d8e02cd9f9e2cc77208b800abe17d54;p=mesa.git Add an expected file for 094-divide-by-zero-short-circuit The expected file here captures the current behavior of glcpp (which is to generate a division-by-zero error) for this case. It's easy to argue that it should be short-circuiting the evaluation and not generating the diagnostic (which happens to be what gcc does). But it doesn't seem like we should force this behavior on our pre-processor, (and, as always, the GLSL specification of the pre-processor is too vague on this point). --- diff --git a/src/glsl/glcpp/tests/094-divide-by-zero-short-circuit.c b/src/glsl/glcpp/tests/094-divide-by-zero-short-circuit.c index a9c6f36def8..04497b17913 100644 --- a/src/glsl/glcpp/tests/094-divide-by-zero-short-circuit.c +++ b/src/glsl/glcpp/tests/094-divide-by-zero-short-circuit.c @@ -1,2 +1,13 @@ +/* glcpp is generating a division-by-zero error for this case.
