2010-05-17Fix (and add test for) function-like macro invocation with newlines.Carl Worth
The test has a newline before the left parenthesis, and newlines to separate the parentheses from the argument. The fix involves more state in the lexer to only return a NEWLINE token when termniating a directive. This is very similar to our previous fix with extra lexer state to only return the SPACE token when it would be significant for the parser. With this change, the exact number and positioning of newlines in the output is now different compared to "gcc -E" so we add a -B option to diff when testing to ignore that.
2010-05-14Don't return SPACE tokens unless strictly needed.Carl Worth
This reverts the unconditional return of SPACE tokens from the lexer from commit 48b94da0994b44e41324a2419117dcd81facce8b . That commit seemed useful because it kept the lexer simpler, but the presence of SPACE tokens is causing lots of extra complication for the parser itself, (redundant productions other than whitespace differences, several productions buggy in the case of extra whitespace, etc.) Of course, we'd prefer to never have any whitespace token, but that's not possible with the need to distinguish between "#define foo()" and "#define foo ()". So we'll accept a little bit of pain in the lexer, (enough state to support this special-case token), in exchange for keeping most of the parser blissffully ignorant of whether tokens are separated by whitespace or not. This change does mean that our output now differs from that of "gcc -E", but only in whitespace. So we test with "diff -w now to ignore those differences.
2010-05-10Add a very simple test for the pre-processor.Carl Worth
Validate desired test cases by ensuring the output of glcpp matches the output of the gcc preprocessor, (ignoring any lines of the gcc output beginning with '#'). Only one test case so far with a trivial #define.
