This is a much-needed, much-delayed refresh against the current CVS. It should work better with gcc-4. The list of changes is included after the unsubscribe info. This is a list of changes from three binutils NEWS files. Some entries may not be pertinent to Cygwin. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

It can load the same shared objects used by gold and uses them to provide basic support for new file formats. * The verilog memory hex dump file format is now supported as an output format for objcopy. * Add --file-alignment, --heap, --image-base, --section-alignment, --stack and --subsystem command line options to objcopy, which will set PE optional header. * Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. * --as-needed now links in a dynamic library if it satisfies undefined symbols in regular objects, or in other dynamic libraries. In the latter case the library is not linked if it is found in a DT_NEEDED entry of one of the libraries already linked. * Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to add absolute paths for -S. * Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- back to old import table generation with null element prefix. * Added --identify-strict switch to cause --identify to report an error when the import library is associated with multiple DLLs. * Added --identify option to dlltool, which determines the name of the DLL associated with the specified . * Support for PowerPC booke64 instructions has been removed. The assembler no longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. Changes in 2.19: * Added -wL switch to dump decoded contents of .debug_line. * Added support for "thin" archives which contain pathnames pointing to *** gas changes: * Add support for common symbol alignment to PE formats. * Add support for the new discriminator column in the DWARF line table, with a discriminator operand for the .loc directive. * Add support for Sunplus score architecture. * The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to indicate that if the symbol is the target of a relocation, its value should not be use. Instead the function should be invoked and its result used as the value. * Add support for Lattice Mico32 (lm32) architecture. Changes in 2.19: * New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind tables without runtime relocation. * New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which adds compatibility with H'00 style hex constants. *** ld changes: * PE targets now support a GNU extension to allow the alignment of common common symbols to be specified. This support uses custom options in the .drectve section, which will be disregarded by the native tools. * PE targets now add primitive support for ELF version scripts; symbols are not versioned, but the local and global symbol visibility directives are respected when filtering symbols in auto-export mode. * New option --no-export-dynamic to undo the effect of the -E and --export-dynamic options. * ELF: --warn-alternate-em option to warn if an object has alternate ELF machine code. * New script function REGION_ALIAS to add alias names to memory regions. * PE targets no longer make use of the long section names PE extension to the COFF format when generating executable images, by default. The old (slightly non-conformant) behaviour can still be invoked by using the new '--enable-long-section-names' command-line option. It is also enabled automatically in the presence of un-stripped debug information, as GDB needs to be able to find the debug info sections by their full names. * For GNU/Linux systems the linker will now avoid processing any relocations made against symbols of the STT_GNU_IFUNC type and instead emit them into the resulting binary for processing by the loader. * --as-needed now links in a dynamic library if it satisfies undefined symbols in regular objects, or in other dynamic libraries. In the latter case the library is not linked if it is found in a DT_NEEDED entry of one of the libraries already linked. * Add a new command line option, -Ttext-segment ADDR, for ELF targets to set the address of the first byte of the text segment. * Add support for Sunplus score architecture. * Add new option --use-nul-prefixed-import-tables to ld for PE targets to allow fallback to old import table generation with null element prefix. * Windows PE systems now support a new --exclude-modules-for-implib option, allowing users to partition object files and archive members between a DLL and its associated import library as they are generated during linking. * Add support for Lattice Mico32 (lm32) architecture. * Add CR16 ELF --embedded-relocs (used to embedded relocations into binaries for Embedded-PIC code) option. * Add to the PE/PE+ targets the support of two different kinds of pseudo-relocations. They can be selected by the switches --enable-runtime-pseudo-reloc-v1 and --enable-runtime-pseudo-reloc-v2. For the switch --enable-runtime-pseudo-reloc it uses for 32-bit runtime pseudo relocation version one, for 64-bit the version two. Changes in 2.19: * Linker scripts support a new INSERT command that makes it easier to augment the default script.
