Hi,
I don't have an ARM test system available but it is a new test...
The idea of abitest is to check compatibility of TCC calling convention
with GCC, but I also made rather a lot of changes since compatibility
with GCC on x86 an x86-64 had a lot of problems in corner cases. I think
that ARM should use a hidden pointer to return the data in
ret_2float_test, but reading the ARM EABI spec a structure with 2 floats
in might count as a "64-bit containerized vector" and thus would be
returned in r0 and r1. In that case I think the thing to do is modify
gfunc_sret to detect this.
