Thanks Corinna,

I don't have write perms on newlib - can I request them, or can you
apply the patch for me?

Everything applied.

This patch breaks breaks existing mb-gcc compilations.

Please revert the patch until it can be fixed.

Hi Michael,

Can you provide details regarding the breakage?

This should be a separate library and not linked in by default - what sort
of compilation errors are you seeing?

Hi Michael,

Reverting the patch breaks running the GCC + binutils testsuites on QEMU-user
which has proven to be an extremly valuable test environment for non linux
targets. It also doesn't break Xilinx internal testing environment on real HW.
I don't know how you test, but if you can post instructions, we will be happy
to help with fixing the issues you are seeing.

You can't break builds in FSF-gcc, simply because it doesn't break your internal

Here is a sample test:
mb-gcc testsuite/gcc.c-torture/execute/strcpy-1.c  -fno-diagnostics-show-caret
-fdiagnostics-color=never  -w  -O3 -fomit-frame-pointer  -mno-xl-soft-mul
-mxl-barrel-shift -mcpu=v6.00.a -Wl,-defsym -Wl,_HEAP_SIZE=0x1000000 -Wl,-defsym -Wl,_STACK_SIZE=0x80000 -L microblaze_0/lib -lxil
-TLinkScr.ld  -lm   -o strcpy-1.x3

LinkScr.ld and libxil are from either EDK9.2i or EDK-14.2.

I don't have the failure log at the moment.
