patch applied (c2hs): Allow various GNU C builtins that take types as parameters

Sun Mar 25 06:00:26 PDT 2007 Duncan Coutts <duncan.coutts(a)worc.ox.ac.uk> * Allow various GNU C builtins that take types as parameters We can parse normal builtins, but these ones are not just functions since they take types as parameters so have to be recognised specially in the parser. They are entered into the AST with only a place holder, not the full info. M ./c2hs/c/CAST.hs -1 +4 M ./c2hs/c/CLexer.x +5 M ./c2hs/c/CParser.y +22 M ./c2hs/c/CTokens.hs +6

patch applied (c2hs): GNU C allows comitting the middle expr in conditional expressions
by Duncan Coutts 25 Mar '07

25 Mar '07

Sun Mar 25 05:50:51 PDT 2007 Duncan Coutts <duncan.coutts(a)worc.ox.ac.uk> * GNU C allows comitting the middle expr in conditional expressions so normally it's: <condition-exp> ? <then-exp> : <else-exp> and GNU allows: <condition-exp> ? : <else-exp> which in the 'then' case evaluates to <condition-exp>. The advantage here is that the condition exp is evaluated only once. M ./c2hs/c/CAST.hs -1 +1 M ./c2hs/c/CNames.hs -1 +1 M ./c2hs/c/CParser.y -1 +7
