Are there any D platforms where -nofloat is useful? If we're
not getting rid of it then it needs to be documented (the above
issue).
Well, I couldn't find any documentation on what this means, so I
can't really say. Does it disable floating point usage
completely, or does it force software emulation?
There are a couple people in this community interested in
bringing D to 32-bit microcontrollers. Most of the 32-bit ARM
Cortex microcontrollers don't have an FPU. For the few that do,
here are the attributes in GCC
(http://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html) needed to
specify the configuration.
-mfloat-abi=name
-mfpu=name
-mfp16-format=name
But, these are target specific. Since DMD doesn't support any ARM
platform, I suspect this is irrelevant, but there, you have it
anyway.
