[Openocd-development] arm-elf, mips-elf and powerpc-eabi Windows only toolchain ready for testing

[Ø. H. <oyv...@zy...>]

http://www.zylin.com/gccbinary.html now has links to Windows hosted
arm-elf, mips-elf and powerpc-eabi.

I believe powerpc-elf should be retired, but I'm awaiting feedback on whether
that toolchain makes any sense.


Warning!!!!! these are stored as tar.bz2 files which evidently e.g. 7Zip does
not propery decompress(problems with symlink?).  When this happens
you get weird error messages CreateProcess failing.

They were properly decompressed using Cygwin tar. Perhaps Windows
toolchains would be better uploaded as .zip files?

I uploaded  http://www.zylin.com/gcc/binaries/windows/arm-elf.zip as a test...

The arm-elf in particular should cover *all* ARM CPU types, including
Cortex, XScale, Thumb, etc. It's 100mByte though :-)

GDB is in there as well.

Building the damn thing was a challenge, now these toolchains need
some *minimal* testing before they can be recommended any help
with that is greatly appreciated.

The arm-elf toolchain is in many ways the ultimate multilib test...

If you need big endian, no float, thumb2 code or any other such
weird combination, then the arm-elf.tar.bz2 should do it... :-)

Feedback welcome!


Example:




C:\temp>type test.c
#include <stdio.h>

int main(int argc, char **argv)
{
printf("Hello world\n");
}
C:\temp>arm-elf-gcc test.c

C:\temp>arm-elf-gdb a.out
