* calls.c (store_one_arg): Set default alignment for BLKmode arguments to BITS_PER_UNIT when ARGS_GROW_DOWNWARD and the padding direction is downward. * function.c (pad_below): Always compile. (locate_and_pad_parm): If defined ARGS_GROW_DOWNWARD, pad argument to alignment when it is not in a register or REG_PARM_STACK_SPACE is true. Pad below when the argument is not in a register and the padding direction is downward. * pa-64.h (MUST_PASS_IN_STACK): Move define to pa.h. (PAD_VARARGS_DOWN): Define. * pa.c (function_arg_padding): Revise padding directions to make them compatible with the 32 and 64-bit runtime architecture documentation. (hppa_va_arg): Add code to handle variable and size zero arguments passed by reference on TARGET_64BIT. Reformat. (function_arg): Use a PARALLEL for BLKmode and aggregates args on TARGET_64BIT. Use a DImode PARALLEL for BLKmode args 5 to 8 bytes wide when !TARGET_64BIT. Move forward check for mode==VOIDmode. Add comments. * pa.h (MAX_PARM_BOUNDARY): Correct define for TARGET_64BIT. (RETURN_IN_MEMORY): Return size zero types in memory. (FUNCTION_VALUE): Return TFmode in general registers. (MUST_PASS_IN_STACK): Define. (FUNCTION_ARG_BOUNDARY): Simplify. (FUNCTION_ARG_PASS_BY_REFERENCE): Pass variable and zero sized types by reference. (FUNCTION_ARG_CALLEE_COPIES): Define to FUNCTION_ARG_PASS_BY_REFERENCE. From-SVN: r57226 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
