#  DJGPP specific changes to libbfd and libiberty shared
#  by the DJGPP ports of binutils and gdb.


2020-12-18  Juan Manuel Guerrero  <juan.guerrero@gmx.de>

	* bfd/bfd-in.h [__DJGPP__]:  Provide the declaration of
	coff_64k_relocation_enabled.

	* bfd/cache.c (bfd_cache_max_open) [__DJGPP__]:  Do not use getrlimit
	to check for the amount of files that can be opened.  Use a fixed value
	of 16.

	* bfd/coffcode.h (coff_set_alignment_hook): Use coff_64k_relocation_enabled
	where appropriate to enable/disable the coff 64k relocation support.

	* bfd/coffswap.h (coff_swap_scnhdr_in) [COFF_GO32_EXE, COFF_GO32]:
	Iff reading an executable file and iff it is the ".text" section
	header calculate the number of lines from the 16 bit field of the
	relocation counter and the 16 bit filed of the line counter.
	(coff_swap_scnhdr_out) [COFF_GO32_EXE, COFF_GO32]:
	Use the same Ansatz to identify a .text section of an executable like
	in coff_swap_scnhdr_in.
	- Iff building an executable file and iff it is the ".text" section
	header store the upper 16 bits of the line counter in the relocation
	counter.
	- Iff not building an executabe file or iff building an executable file
	but iff it is not the ".text" section header then:
	  1) if the relocation counter is greater the 65534 set the relocation
	     counter to 65535 and set the IMAGE_SCN_LNK_NRELOC_OVFL bit.
	     The relocation counter overflow is handled elsewhere.
	  2) if the line counter is greater than 65535 then abort.
	(coff_swap_scnhdr_in, coff_swap_scnhdr_out) [COFF_GO32_EXE, COFF_GO32]:
	Use coff_64k_relocation_enabled where appropriate to enable/disable the
	coff 64k relocation support.

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

	* bfd/init.c [__DJGPP__]:  Define coff_64k_relocation_enabled.
	(bfd_init):  Read the environment variable DISABLE_64K_RELOC_SUPPORT
	to set the value of coff_64k_relocation_enabled.

	* bfd/Makefile.in:  Force the regenaration of bfd-in2.h to provide the
	declaration of coff_64k_relocation_enabled.  Force the regenaration of
	libcoff.h to provide the definition of obj_go32.

	* include/bfdlink.h:  Pacify compiler.

	* include/coff/internal.h:  Pacify compiler.

	* include/simple-object.h:  Pacify compiler.

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

	* libiberty/cp-demangle.c (d_demangle_callback, d_expression_1, d_print_comp):
	Pacify compiler.  Rename functions and variables that shadow the
	corresponding libc ones.
        (d_bare_function_type): Pacify compiler.  Rename functions and
	variables that shadow the corresponding libiberty ones.

	* libiberty/floatformat.c (floatformat_to_double):  Pacify compiler.
	Rename functions and variables that shadow the corresponding libc ones.

	* libiberty/hashtab.c (find_empty_slot_for_expand, htab_find_with_hash,
	htab_find_slot_with_hash):  Pacify compiler.  Rename functions and
	variables that shadow the corresponding libc ones.

	* libiberty/make-relative-prefix.c:  DJGPP specific adjustments.
	Taken from bnu219s2.zip.

	* libiberty/make-temp-file.c:  DJGPP specific adjustments.
	Taken from bnu219s2.zip.

	* libiberty/pex-common.c (temp_file, pex_run_in_environment):  Pacify
	compiler.  Rename functions and variables that shadow the corresponding
	libc ones.

	* libiberty/simple-object.c (simple_object_copy_lto_debug_sections,
	handle_lto_debug_sections):  Pacify compiler.  Rename functions and
	variables that shadow the corresponding libc ones.

	* libiberty/simple-object-coff.c (simple_object_coff_write_to_file):
	Pacify compiler.  Rename functions and variables that shadow the
	corresponding libc ones.

	* libiberty/simple-object-elf.c (simple_object_elf_write_to_file):
	Pacify compiler.  Rename functions and variables that shadow the
	corresponding libc ones.

	* libiberty/simple-object-mach.c (simple_object_mach_o_segment,
	simple_object_mach_o_write_segment):  Pacify compiler.  Rename
	functions and variables that shadow the corresponding libc ones.

	* libiberty/simple-object-xcoff.c (simple_object_xcoff_write_to_file):
	Pacify compiler.  Rename functions and variables that shadow the
	corresponding libc ones.

	* libiberty/stack-limit.c (stack_limit_increase):  Pacify compiler.
	Rename functions and variables that shadow the corresponding libc ones.
