Subject: ast: Initialize location data in constructor of all ast_node objects.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ec9675ec533cc0c0c7b1c738280e9b9adf2591fb;p=mesa.git

ast: Initialize location data in constructor of all ast_node objects.

This prevents using uninitialized data in _msea_glsl_error in some
cases, (including at least 6 piglit tests). Thanks to valgrind for
pointing out the problem!
