version into different directories. Which version a given port uses is controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which uses the same code we had before) by default. 32-bit platforms that don't need extended precision support might get better performance by using 32. Set the ARM port to use the 32-bit version of SoftFloat, since this is more than a factor of two faster than the 64-bit version. This should get the floating-point performance back to what it was in 1.5.

This is a modified version of part of John Hauser's SoftFloat 2a package.
|
|
This version has been heavily modified to support its use with GCC to
|
|
implement built-in floating-point operations, but compiling
|
|
softfloat.c without SOFTFLOAT_FOR_GCC defined should get you the same
|
|
results as from the original.
