From 5dbdc341e8e8502ab5d98784a24b54c6f3907472 Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Fri, 20 Jun 2014 14:28:20 -0700 Subject: glsl/glcpp: Add testing for EOF sans newline (and fix for , ) 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 action was restricted only to the state so it would fail to get invoked if the EOF was encountered in the or the 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).
