PING^2 [PATCH] Support for AMD64 targets running GNU/kFreeBSD
Please can this patch be considered? It's several months old (sent in
Jan 2011), and it is critical to use of GCC on GNU/kFreeBSD.

Support for AMD64 targets running GNU/kFreeBSD.
* config.gcc (tm_file): Include `i386/kfreebsd-gnu.h' on
x86_64-*-kfreebsd*-gnu.
* config/i386/kfreebsd-gnu.h
(GLIBC_DYNAMIC_LINKER32): If defined, redefine to "/lib/ld.so.1".
(GLIBC_DYNAMIC_LINKER64): If defined, redefine to
"/lib/ld-kfreebsd-x86-64.so.1".
* config/i386/linux.h (LINK_EMULATION): Redefine this macro
to a noop filter, which can be overriden by other headers.
* config/i386/linux64.h (LINK_SPEC): Process emulation names
through LINK_EMULATION().
* config/kfreebsd-gnu.h (LINK_EMULATION): Redefine to append
a "_fbsd" suffix.
* config/i386/kfreebsd-gnu.h (LINK_EMULATION): Remove macro
(superceded by the definition in config/kfreebsd-gnu.h).

PING^4 APPROVED patch for AMD64 targets running GNU/kFreeBSD, anyone?
This patch for AMD64 targets running GNU/kFreeBSD has been approved
already, would anyone be so kind to commit it? I'm afraid I don't have
write perms currently.
See: http://gcc.gnu.org/ml/gcc-patches/2011-06/msg00884.html
Thank you very much :-)

[PATCH] split mips/gnu-user.h from mips/linux.h
Hi!
This patch splits those bits from:
config/mips/linux.h
config/mips/linux64.h
which are applicable to GNU userland, into:
config/mips/gnu-user.h
config/mips/gnu-user64
respectively. It is analogous to the split that was performed for
config/i386/* by Joseph Myers in r172271.
I've verified that my patch doesn't cause any regression (resulting
gcc/xgcc is identical both for mips-*-linux and mips64*-linux).

Re: [PATCH] split mips/gnu-user.h from mips/linux.h
Hi Richard, Thanks for committing! Just one small note: 2011/7/19 Richard Sandiford : > needs to deal with linux64.h as well. I also kept the copyright notice > the same on linux.h (even though it's only a one-liner now). > > Applied with those changes, thanks. It's probably harmless, but with this change if --enable-targets=all is used, then mips/gnu-user.h is included twice. The second one can be removed. -- Robert Millan

Support for AMD64 targets running GNU/kFreeBSD.

x86_64-*-kfreebsd*-gnu.
* config/i386/kfreebsd-gnu.h
(GLIBC_DYNAMIC_LINKER32): If defined, redefine to "/lib/ld.so.1".

"/lib/ld-kfreebsd-x86-64.so.1".
* config/i386/linux.h (LINK_EMULATION): Redefine this macro
to a noop filter, which can be overriden by other headers.
* config/i386/linux64.h (LINK_SPEC): Process emulation names
through LINK_EMULATION().
* config/kfreebsd-gnu.h (LINK_EMULATION): Redefine to append
a "_fbsd" suffix.
* config/i386/kfreebsd-gnu.h (LINK_EMULATION): Remove macro
(superceded by the definition in config/kfreebsd-gnu.h).
