tags 645692 + upstream fixed-upstream pending
thanks
After some more work to support relocations that gcc generate when compiling
for armv6 or greater and Thumb-2, armhf is now finally supported upstream.
There is still a few bits missing to make R_ARM_THM_JUMP24 work when the
target is PLT but

DONE
So only correct assignment of float register is missing. There might also be a
regression somewhere but I'm not sure yet. I guess if I continue on this rythm
a patch should be ready

retitle 645692 Support for hard-float calling convention
thanks
Time for another update.
When trying to add support for homogeneous aggregate (which are now passed in
VFP register with armhf calling convention), I realized a few things in the
current code are wrong for armhf:
* bug when manipu

Small update about the progress so far:
I built a patch which add basic support for hardfloat ABI. It correctly place
float argument in VFP registers when calling a function and can fall back to
softfp if the function called is variadic. However, still a lot remains to be
done:
1) Return float
