gcc/ * config.gcc (arm-wrs-vxworks): Remove dbxelf.h from tm_file. Add vx-common.h. Include vxworks.h between vx-common.h and arm/vxworks.h. * config/vx-common.h (DWARF2_UNWIND_INFO): Undefine before redefining. * config/vxworks.h (TARGET_ASM_CONSTRUCTOR): Likewise. (TARGET_ASM_DESTRUCTOR): Likewise. * config/arm/vxworks.h (TARGET_OS_CPP_BUILTINS): Check arm_arch_xscale instead of arm_is_xscale. Use VXWORKS_OS_CPP_BUILTINS. (OVERRIDE_OPTIONS, SUBTARGET_CPP_SPEC): Define. (CC1_SPEC): Add -tstrongarm. Line up backslashes. (VXWORKS_ENDIAN_SPEC): Define. (ASM_SPEC): Add VXWORKS_ENDIAN_SPEC. (LIB_SPEC, STARTFILE_SPEC, ENDFILE_SPEC): Redefine to their VXWORKS_* equivalents. (LINK_SPEC): Likewise, but add VXWORKS_ENDIAN_SPEC. (ASM_FILE_START): Delete. (TARGET_VERSION): Reformat. (FPUTYPE_DEFAULT, FUNCTION_PROFILER): Define. (DEFAULT_STRUCTURE_SIZE_BOUNDARY): Define. * config/arm/t-vxworks (LIB1ASMSRC, LIB1ASMFUNCS): Define. (FPBIT, DPBIT): Define. (fp-bit.c, dp-bit.c): New rules. (MULTILIB_OPTIONS): Add strongarm, -mrtp and -mrtp/-fPIC multilibs. (MULTILIB_MATCHES, MULTILIB_EXCEPTIONS): Define. * config/arm/arm-protos.h (arm_emit_call_insn): Declare. * config/arm/arm.h: Include vxworks-dummy.h. * config/arm/arm.c (arm_elf_asm_constructor, arm_elf_asm_destructor): Mark with ATTRIBUTE_UNUSED. (arm_override_options): Do not allow VxWorks RTP PIC to be used for Thumb. Force r9 to be the PIC register for VxWorks RTPs and make it incompatible with -msingle-pic-base. (arm_function_ok_for_sibcall): Return false for calls that might go through a VxWorks PIC PLT entry. (require_pic_register): New function, split out from... (legitimize_pic_address): ...here. Do not use GOTOFF accesses for VxWorks RTPs. (arm_load_pic_register): Handle the VxWorks RTP initialization sequence. Use pic_reg as a shorthand for cfun->machine->pic_reg. (arm_emit_call_insn): New function. (arm_assemble_integer): Do not use GOTOFF accesses for VxWorks RTP. * config/arm/arm.md (UNSPEC_PIC_OFFSET): New unspec number. (pic_offset_arm): New pattern. (call, call_value): Use arm_emit_call_insn. (call_internal, call_value_internal): New expanders. * config/arm/lib1funcs.asm (__PLT__): Define to empty for VxWorks unless __PIC__. From-SVN: r125196 |

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.
