Hi Guys,
I am applying the patch below to fix a couple of problems building
libgcc for the RX target. The first is that when 32-bit doubles are
enabled we need to make sure that we never try to construct a 64-bit
double type. This is done in rx-lib.h, but it was only being enabled
when constructing the float-type functions. The patch enables the fix
for when double-type functions are being constructed as well.
The second fix is to prevent a extraneous renaming of the floatsisf
and floatunsisf functions when building libgcc width 32-bit doubles
enabled.
Cheers
Nick

* config/rx/rx-lib.h: Always restrict doubles to the SF type when
64-bit doubles are not enabled.
* config/rx/rx-abi.h: Fix extraneous renaming of the floatsisf
and floatunsisf functions.
