6bd4bdb0f9 Updated 'noValidConfiguration' message. It should not write this message when there is no code. It should be possible to see the preprocessor errors otherwise it is hard to fix the configuration. 2018-05-15 15:42:54 +02:00

9ee6068e20 Remove duplicate namespace aliases so they don't produce syntax errors. (#1222) 
* Remove duplicate namespace aliases so they don't produce syntax errors.

DACA2 results showed new SymbolDatabase syntax errors when duplicate
namespace aliases were simplified improperly. The solution is to remove
them in the tokenizer when found.

* Add tests for deleting namespace aliases at end of token list.

* Use eraseTokens to delete multiple tokens at once.

184537884f Don't remove the volatile keyword so we can properly overload functions. (#1218) 
* Don't remove the volatile keyword so we can properly overload functions.

I fixed all the checks that had tests that use volatile.  There will
probably be more changes needed due to lack of test coverage for
volatile in some checks.

* Fix unused private function warning.
