This includes binutils, gcc, gdb and uClibc-ng. Latest release of ARC gcc (as of today it is "arc-2015.06") is based on upstream gcc 4.8.4. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/gcc Latest release of ARC binutils (as of today it is "arc-2015.06") is based on upstream binutils 2.23. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06 Latest release of ARC GDB (as of today this is "arc-2015.06-gdb") is based on upstream gdb 7.9.1. Sources are available on GitHub, see: https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb Note that for binutils and gdb that come from unified git repository (which is the case for upstream binutils/gdb today) we need to disable building of gdb in binutils and binutils in gdb hence in binutils: ------>8------ --disable-sim --disable-gdb ------>8------ and in gdb: ------>8------ --disable-binutils --disable-ld --disable-gas ------>8------ Also in gdb we disable sim because if the following breakage while building with it: ------------>8------------ /usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \ -mono -fast -pbb -switch sem5-switch.c \ -cpu a5f -infile ./mloop5.in \ -outfile-suffix 5 unknown option: bash Makefile:699: recipe for target 'stamp-5mloop' failed make[7]: *** [stamp-5mloop] Error 1 ------------>8------------ Cc: Felix Fietkau <nbd@openwrt.org> Cc: John Crispin <blogic@openwrt.org> Cc: Jonas Gorski <jogo@openwrt.org> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> SVN-Revision: 47438

If your target CPU does not have a Floating Point Unit (FPU) or a
|
|
kernel FPU emulator, but you still wish to support floating point
|
|
functions, then everything will need to be compiled with soft floating

If you're specifying an addition target architecture,

you'll probably need to also provide options to make

the compiler use this alternate arch.

For example, if you're building a compiler that can build
|
|
both powerpc and powerpc64 binaries, you'll need to
|
|
specify -m64 here.
