Yes, the reason is that newer binutils work this way, and otherwise they will not work, and complain they cannot find the correct BFD at runtime. In newer binutils, 'elf64-x86-64' is generic, and 'elf-x86-64-freebsd' is freebsd-specific. Previously we needed a hack (elf-fbsd-brand.c) to bolt on detection of FreeBSD ELF files (using the OSABI field), but that hack is no longer needed, except for ia64. I may even fix that one, so we can drop the hack. :) > this effectively prevents 3rd party > compilers (their driver) from working out of the box on freebsd.. > as they expect the format to be elfX-FOO wihtout the -freebsd suffix Then they should be adapted to cope with newer binutils than from >3 years ago. :) E.g. something like: if platform==FreeBSD then strcat(output_format, "-freebsd") Also, for i386 the output format has always been elf-i386-freebsd, so this change only makes it more consistent, really. The same goes for sparc64, where the output format name has been changed from (generic) 'elf64-sparc' to 'elf64-sparc-freebsd'.
