* config.gcc: Move inclusion of arm elf specific header files

from the files themselves into the tm_file variable. Make
|
||||
sure that elfos.h is included before target specific elf
|
||||
headers.
|
||||
* config/arm/aout.h (NO_DOLLAR_IN_LABEL): Only define if not
|
||||
already defined.
|
||||
(ASM_OUTPUT_ASCII, ASM_OUTPUT_SKIP): Protect definition.
|
||||
* config/arm.arm.h (TARGET_MEM_FUNCTIONS,
|
||||
ASM_OUTPUT_CASE_LABEL): Protect definition.
|
||||
(CC1_SPEC, FP_DEFAULT, ARM_FUNCTION_PROFILE): Only define if
|
||||
not already defined.
|
||||
* config/arm/conix-elf.h: (USER_LABEL_PREFIX,
|

LOCAL_LABEL_PREFIX, MAKE_DECL_ONE_ONLY, UNIQUE_SECTION):
|
||||
Remove duplicate definition.
|
||||
(READONLY_DATA_SECTION, SUBTARGET_EXTRA_SECTION,
|
||||
(SUBTARGET_EXTRA_SECTION_FUNCTION, RDATA_SECTION_ASM_OP,
|
||||
(RDATA_SECTION_FUNCTION): Remove redundant definition.
|
||||
(STARTFILE_SPEC, ENDFILE_SPEC): Protect definition.
|
||||
Remove inclusion of arm/elf.h.
|
||||
* config/arm/unknown-elf.h: as for conix-elf.h.
|
||||
(STARTFILE_SPEC): Include crti.o and crtn.o.
|
||||
* config/arm/linux-elf.h: as for conix-elf.h.
|
||||
* config/arm/ecos-elf.h: Remove inclusion of unknown-elf.h.
|

* config/arm/strongarm-elf.h: Remove inclusion of
|
||||
unknown-elf.h.
|

* config/arm/xscale-elf.h: Remove inclusion of unknown-elf.h.
|
||||
* config/arm/unknown-elf-oabi.h: Remove inclusion of
|
||||
unknown-elf.h and elf.h.
|
||||
* config/arm/uclinux-elf.h: Remove inclusion of linux-elf.h.
|
||||
* config/arm/linux-gas.h (DBX_DEBUGGING_INFO,
|
||||
ASM_WEAKEN_LABEL): Remove redundant definition.
|
||||
* config/arm/elf.h: Test for inclusion of elfos.h
|

(USER_LABEL_PREFIX, ASM_DECLARE_RESULT, ASM_DECLARE_RESULT,
|

ASM_DECLARE_OBJECT_NAME, ASM_FINISH_DECLARE_OBJECT_NAME,
|
||||
SUBTARGET_EXTRA_SECTION, SUBTARGET_EXTRA_SECTION_FUNCTION,
|
||||
EXTRA_SECTIONS, INT_ASM_OP, ASM_WEAKEN_LABEL): Remove
|

redundant definition.
|
||||
(TYPE_OPERAND_FMT, ASM_DECLARE_FUNCTION_NAME,
|
||||
ASM_DECLARE_FUNCTION_SIZE, ASM_OUTPUT_INTERNAL_LABEL,
|
||||
ASM_OUTPUT_ALIGNED_COMMON): Protect definition.
|
||||
* t-arm-elf (EXTRA_MULTILIB_PARTS): Add crti.o and crtn.o.
|
||||
Add rules to build crti.o and crtn.o
|
||||
* crti.asm: New file.
|
||||
* crtn.asm: New file.
|
