Changed the handling of variadic intrinsics a bit. Removed the -fp80 option and made real be 80bit floats on X86, this is what the D spec really says it should be and fixes a bunch of issues. Changed the handling of parameter attributes to a bit more generalized approach. Added sext/zext attributes for byte/short/ubyte/ushort parameters, fixes #60 . Parameter attribs now properly set for intrinsic calls if necessary. Made the tango.math.Math patch less intrusive. Fixed/added some mini tests.

module tangotests.mem6;

extern(C) int printf(char*,...);

int main(){
        int[] index;
        char[] value;

        foreach(int i, char c; "_\U00012345-"){
                printf("str[%d] = %d\n", i , cast(int)c);
                index ~= i;
                //value ~= c;
        }
        printf("done\n");

        return 0;
