#  DJGPP specific changes to binutils for the DJGPP port of binutils
#  excluding the changes specific to libbfd and libiberty.


2020-12-19 Juan Manuel Guerrero  <juan.guerrero@gmx.de>

	* binutils/ar.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/coffdump.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/config.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.

	* binutils/cxxfilt.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/nm.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/objcopy.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/objdump.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/readelf.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.
	(print_symbol) [__DJGPP__]:  Use mbtowc instead of mbrtowc.

	* binutils/size.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/srconv.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/strings.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* binutils/sysdump.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* config.sub:  Use uname result to set basic_machine value instead of
	hardcoded one.

	* djgpp/build.sh:  DJGPP specific shell script to adjust, configure and
	compile progs and libs.  To support the build of a binutils version used
	by a cross-compiler, the sed scripts that modified bfd/Makefile.in and
	config.in files have been removed.  This change is now part of the patch.

	* gas/as.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.

	* gas/config/obj-coff-seh.c (get_pxdata_name):  Pacify compiler.

	* gas/config.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.

	* gas/dw2gencfi.c (get_debugseg_name):  Pacify compiler.

	* gold/config.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.

	* gprof/gconfig.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.

	* gprof/gprof.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.
	(main) [COFF_GO32_EXE, COFF_GO32]:  Call bfd_init to check to enable/disable
	the coff 64k relocation support.

	* ld/config.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.
	[__DJGPP__]:  For DJGPP versions greather than 2.03 enable support to
	resolve multiple symbol definitions due to the use of DXE3 modules by
	defining the HAVE_DXE3_SUPPORT macro.

	* ld/configure:  Set HAVE_DXE3_SUPPORT to 1 if using DJGPP as taget OS.

	* ld/ldfile.c [__DJGPP__]:  New function map_LFN_to_SFN.
	Maps a library long filename to a short filename according to a table
	defined in /dev/env/DJDIR/lib/libnames.tab.
	(ldfile_try_open_bfd) [__DJGPP__]:  If library is not found by its
	original name try the mapped SFN one.

	* ld/ldmain.c (main):  Use STRIP_FULL_PATH_AND_EXTENSION to adjust file name.
	(multiple_definition) [HAVE_DXE3_SUPPORT]:  If the linker is compiled
	for DX3 module support, it will be able to resolve multiple symbol definitions.
	This is usually the case when different DXE3 import libraries provide the same
	wrapper function to call certain function from the DXE3 module.  If the symbol
	is defined in a static library and in an import library, the import library
	definition takes always precedence over the static library.  This is to
	guarantee that all aplications linked with the same DXE3 module use the same
	functionality and not the one from the static library.  The DXE3 module
	provides functions ported to DJGPP, the functions from the static library
	may not be ported to DJGPP and may behave differently.
	(multiple_definition) [HAVE_DXE3_SUPPORT]:  Allow also the older file name
	$$dxe$$.o as identifier of import libraries generated by dxe3gen.exe.

	* ld/libnames.tab:  New file providing the mapping table between the
        library's LFN to SFN.  LFN to SFN mapping for PCRE2 libraries added.

	* ld/scripttempl/i386go32.sc:  DJGPP specific adjustments to the linker
	script.  Taken from djcross-binutils-2.19.1-10ap.src.rpm.

	* opcodes/config.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	They are all NO-OPS for other OSes.

	* libctf/config.h.in [__DJGPP__]:  Added DJGPP specific macros definitions.
	Define HAVE_TSL_SUPPORT if the gcc version is greather equal than 4.3.0.

	* libctf/swap.h [__DJGPP__]:  bswap_identity_64, bswap_16, bswap_32 and
	bswap_64 reimplemented as macros to avoid issues with the inline versions
	of those functions with different gcc versions.
