glsl/glcpp: Add testing for EOF sans newline (and fix for <DEFINE>, <COMMENT>)
The glcpp implementation has long had code to support a file that ends without a final newline. But we didn't have a "make check" test for this. Additionally, the <EOF> action was restricted only to the <INITIAL> state so it would fail to get invoked if the EOF was encountered in the <COMMENT> or the <DEFINE> case. Neither of these was a bug, per se, since EOF in either of these cases is an error anyway, (either "unterminated comment" or "missing macro name for #define"). But with the new explicit support for these cases, we not generate clean error messages in these cases, (rather than "unexpected $end" from before). Reviewed-by: Jordan Justen <[email protected]>
