Daniel Marjamäki 6c25f3662e Tokenizer::simplifyEnum: Don't simplify enums in function heads. Ticket #3953 2012-09-21 16:17:20 +02:00
Edoardo Prezioso 8e1e8525a3 Partial rewrite of Tokenizer::simplifyComma:
skip '= { .. }' where possible;
hence remove '%num% after comma' check because it's redundant now;
replace round braces counter method with faster 'link skip';
if 'endAt' is 'NULL' after finding the ';' token, exit the function;
hence remove redundant 'tok != NULL' check after simplifying 'return' code.
