From: Ian Romanick <ian.d.roman...@intel.com>
GL_MESA_shader_integer_functions does not add the precise qualifier, so
all of these tests should fail.
cd tests/spec/mesa_shader_integer_functions/compiler
cp -a ../../arb_gpu_shader5/compiler/precise-qualifier .
cd precise-qualifier
for i in *; do
sed --in-place -e 's/1[.]50/1.30/g;s/150/130/g' \
-e 's/ARB_gpu_shader5/MESA_shader_integer_functions/g' \
-e 's/expect_result: pass/expect_result: fail/' \
$i
done
