(MD_STARTFILE_PREFIX) Removee. (FILE_NAME_ABSOLUTE_P): Remove. (CPP_SPEC): Do not read macros from sys/version.h. (LINK_COMMAND_SPEC): Remove. (LOCAL_INCLUDE_DIR): Remove. (TARGET_ASM_NAMED_SECTION): Define to i386_djgpp_asm_named_section (TARGET_OS_CPP_BUILTINS): Add DJGPP (non ISO only), __DJGPP, __DJGPP__, unix. (POST_LINK_SPEC): Define to invoke stubify after linker (LIBSTDCXX): Remove define (DBX_REGISTER_NUMBER): Define to svr4_dbx_register_map. (DEFAULT_PCC_STRUCT_RETURN): Define to 1. (SUBTARGET_OVERRIDE_OPTIONS): Remove warning about -mbnu2210. (SUBTARGET_OVERRIDE_OPTIONS): Ignore -fPIC and generate message. (SUBTARGET_OVERRIDE_OPTIONS): Default to DWARF2 debugging info. (IX86_MAYBE_NO_LIBGCC_TFMODE): Remove. (i386_djgpp_asm_named_section): Add propotype of new procedure * config/i386/xm-djgpp.h (NATIVE_SYSTEM_HEADER_DIR): Define. (MD_EXEC_PREFIX): Define (moved from config/i386/djgpp.h). (STANDARD_STARTFILE_PREFIX_1): Define (moved from MD_STARTFILE_PREFIX in config/i386/djgpp.h). (STANDARD_STARTFILE_PREFIX_2): Define identical to STANDARD_STARTFILE_PREFIX_1. (LOCAL_INCLUDE_DIR): Define (moved from config/i386/djgpp.h). (GCC_DRIVER_HOST_INITIALIZATION): Fix reporting fatal installation errors. (MAX_OFILE_ALIGNMENT): Define to 128. (HAVE_FTW_H): Undefine as DJGPP do not have nftw, but have ftw.h. * config/i386/djgpp.c: New file. Add implementation of i386_djgpp_asm_named_section. * config/i386/djgpp.opt: Remove obsolete option -mbnu210. * config/i386/t-djgpp: New file. Add djgpp.o to EXTRA_OBJS. Add rule for building djgpp.o. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@232258 138bc75d-0d04-0410-961f-82ee72b054a4 --- diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 4a8a005..f8784f0 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,41 @@ +2016-01-12 Andris Pavenis + + * config/i386/djgpp.h (PREFERRED_DEBUGGING_TYPE): Define to DWARF2 + (TARGET_ASM_OUTPUT_IDENT): Define to default_asm_output_ident_directive + (MD_EXEC_PREFIX): Remove. + (MD_STARTFILE_PREFIX) Removee. + (FILE_NAME_ABSOLUTE_P): Remove. + (CPP_SPEC): Do not read macros from sys/version.h. + (LINK_COMMAND_SPEC): Remove. + (LOCAL_INCLUDE_DIR): Remove. + (TARGET_ASM_NAMED_SECTION): Define to i386_djgpp_asm_named_section + (TARGET_OS_CPP_BUILTINS): Add DJGPP (non ISO only), __DJGPP, __DJGPP__, unix. + (POST_LINK_SPEC): Define to invoke stubify after linker + (LIBSTDCXX): Remove define + (DBX_REGISTER_NUMBER): Define to svr4_dbx_register_map. + (DEFAULT_PCC_STRUCT_RETURN): Define to 1. + (SUBTARGET_OVERRIDE_OPTIONS): Remove warning about -mbnu2210. + (SUBTARGET_OVERRIDE_OPTIONS): Ignore -fPIC and generate message. + (SUBTARGET_OVERRIDE_OPTIONS): Default to DWARF2 debugging info. + (IX86_MAYBE_NO_LIBGCC_TFMODE): Remove. + (i386_djgpp_asm_named_section): Add propotype of new procedure + + * config/i386/xm-djgpp.h (NATIVE_SYSTEM_HEADER_DIR): Define. + (MD_EXEC_PREFIX): Define (moved from config/i386/djgpp.h). + (STANDARD_STARTFILE_PREFIX_1): Define (moved from MD_STARTFILE_PREFIX in config/i386/djgpp.h). + (STANDARD_STARTFILE_PREFIX_2): Define identical to STANDARD_STARTFILE_PREFIX_1. + (LOCAL_INCLUDE_DIR): Define (moved from config/i386/djgpp.h). + (GCC_DRIVER_HOST_INITIALIZATION): Fix reporting fatal installation errors. + (MAX_OFILE_ALIGNMENT): Define to 128. + (HAVE_FTW_H): Undefine as DJGPP do not have nftw, but have ftw.h. + + * config/i386/djgpp.c: New file.
