Ok.
Does arm-eabi have this support? We probably could
just use the same code.
There's scant bare metal support atm. For sufficiently new ARM core revisions,
gcc will inline operations. In order to get all of it, you have to target
ARMv7.
I threw this together today. It likely needs quite a bit of spit and polish:
[...]
* This has received only compile testing with the arm-rtemseabi multilibs.
There may well be bugs.
[...]
I run the test suite with this patch and now the link errors vanish. I have
currently no time to test the C++ atomics, but it would be nice if we can use
this work in GCC 4.7.
