[pf3gnuchains/gcc-fork.git] / gcc / ChangeLog
1 2007-02-18  Sandra Loosemore  <sandra@codesourcery.com>
2
3         * calls.c (initialize_argument_information): Pass original EXP
4         and STRUCT_VALUE_ADDR_VALUE instead of a list of arguments.  Move
5         code to split complex arguments here, as part of initializing the
6         ARGS array.
7         (expand_call): Remove code that builds a list of arguments and
8         inserts implicit arguments into it.  Instead, just count how many
9         implicit arguments there will be so we can determine the size of
10         the ARGS array, and let initialize_argument_information do the work.
11         (split_complex_values): Delete unused function.
