Subject: glsl: Remove ir_function.cpp:type_compare()
X-Git-Tag: 062012170305~4896^2~413
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6efe1a849586e46028c1eb763175904166ec7076;p=profile%2Fivi%2Fmesa.git

glsl: Remove ir_function.cpp:type_compare()

The function is no longer used and has been replaced by
glsl_type::can_implicitly_convert_to().

Note: This is a candidate for the 7.10 and 7.11 branches.
