[Ecls-list] UFFI returning double is broken?

[anri p.]

Hello.


I've recently encountered a situation, when calling compiled C function like:


double
fn( double a);


from ECL causes to return garbage. It seem that it is ether an UFFI bug
or misconfiguration in the build environment. This happens on linux x86-64,
running 32 bit ECL and compiling C code with -m32 gcc flag. And integer/pointer
C code calling works fine.


So i believe that it is some issue with FP registers returning convention for x86.
Is there any way to change it in a some predictable way in both UFFI/ECL and
gcc options?
