Re: [PATCH] Remove the postincrement queue, take 2
Here is the updated patch, I just used expand_assignment of a PLUS_EXPR
instead of expand_increment. The other change is that I was updating
c_expand_asm_operands, but Steven pointed out it is unused, so this take
removes it.
Thanks very much to rth for taking care of gimplifiers for va_arg.
Bootstrapped/regtested i686-pc-linux-gnu, ok for mainline?
