This patch introduces basic IA MCU psABI support into GCC. * configure.ac (ospace_frag): Enable for i?86*-*-elfiamcu target. * configure: Regenerate. gcc/ * config.gcc: Support i[34567]86-*-elfiamcu target. * config/i386/iamcu.h: New. * config/i386/i386.opt: Add -miamcu. * doc/invoke.texi: Document -miamcu. * common/config/i386/i386-common.c (ix86_handle_option): Turn off x87/MMX/SSE/AVX codegen for -miamcu. * config/i386/i386-c.c (ix86_target_macros_internal): Define __iamcu/__iamcu__ for -miamcu. * config/i386/i386.h (PREFERRED_STACK_BOUNDARY_DEFAULT): Set to MIN_STACK_BOUNDARY if TARGET_IAMCU is true. (BIGGEST_ALIGNMENT): Set to 32 if TARGET_IAMCU is true. * config/i386/i386.c (ix86_option_override_internal): Ignore and warn -mregparm for Intel MCU. Turn on -mregparm=3 for Intel MCU by default. Default long double to 64-bit for Intel MCU. Turn on -freg-struct-return for Intel MCU. Issue an error when -miamcu is used in 64-bit or x32 mode or if x87, MMX, SSE or AVX is turned on. (function_arg_advance_32): Pass value whose size is no larger than 8 bytes in registers for Intel MCU. (function_arg_32): Likewise. (ix86_return_in_memory): Return value whose size is no larger than 8 bytes in registers for Intel MCU. (iamcu_alignment): New function. (ix86_data_alignment): Call iamcu_alignment if TARGET_IAMCU is true. (ix86_local_alignment): Don't increase alignment for Intel MCU. (x86_field_alignment): Return iamcu_alignment if TARGET_IAMCU is true. From-SVN: r225197 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
