[cfe-commits] [PATCH v2] fix failling regression tests due to calling convention markers on recent ARM ubuntu platforms

[David Tweed]

Hi, Alex pointed out that the previous version of the patch didn't alter the
C macros set by the target. This updated version of the patch does that in a
conservative way updating the macros set when the aapcs-vfp PCS is used. To
my understanding, I don't believe that "aapcs + hard float" is equivalent to
vfp, since aapcs does have a way to pass floating point arguments, it's just
not optimal if you've actually got actual floating point registers to use.

Since Alex has ok'd the previous patch, unless anyone raises any problems in
the next day or so I'll commit.

Thanks,
Dave
