Loongson 3A is MIPS64R2-compatible, so this means that it should based
on ISA_MIPS64R2 (not ISA_MIPS64) ?

Script to build a full cross-compilation toolchain from scratch

I'm trying to build a reliable ARM toolchain from scratch (see attached
script/archive for further information). After several days, I managed to
create that toolchain and I compiled a very simple C++ program. 

// main.cxx
#include 
#include 

int main(int ac, char const *av[])
{
std::string app = av[0];

std::cout << "APP: " << app << std::endl;
for (int n = 1; n < ac; ++n) {
std::cout << "\tARG" << n << ": " << av[n] << std::endl;
}
}

When compiling with "armeb-edt-linux-gnueabi-g++ -o main main.cxx" everything
looks fine and the generated code seems legit. 

When compiling with "armeb-edt-linux-gnueabi-g++ -static -o main main.cxx", ld
fails with the following assertion: 

/home/edt/personnal/cross-compile/staging/armeb-edt-linux-gnueabi/usr/lib/gcc/armeb-edt-linux-gnueabi/4.7.3/../../../../armeb-edt-linux-gnueabi/bin/ld:
BFD (GNU Binutils) 2.23.2 assertion fail
/home/edt/personnal/cross-compile/.source/binutils-2.23.2/bfd/elf32-arm.c:7363
collect2: error: ld returned 1 exit status

--- Comment #1 from Emmanuel Deloget  ---
Regarding the build-toolchain.sh script:

I tried to automate every steps of the build process, including wget'ing the
source. 

Once compiled, the toolchain binaries is to be found in
$PWD/staging/armeb-edt-linux-gnueabi/usr/bin; these binaries are using host
librairies that lie in $PWD/staging/host/usr/lib (so you may want to add this
to your LD_LIBRARY_PATH before calling armeb-edt-linux-gnueabi-g++). 

You may want to remove the parts you don't want from the script (for instance,
the last steps compile a linux kernel ; this is of limited interest). 

My build settings: Debian Weezhy with gcc 4.8.1 and binutils 2.22.
