It -provides support for the exceptions bounced from VFP hardware found -on ARM926EJ-S. - -This release has been validated against the SoftFloat-2b library by -John R. Hauser using the TestFloat-2a test suite. Details of this -library and test suite can be found at: - - http://www.jhauser.us/arithmetic/SoftFloat.html - -The operations which have been tested with this package are: - - - fdiv - - fsub - - fadd - - fmul - - fcmp - - fcmpe - - fcvtd - - fcvts - - fsito - - ftosi - - fsqrt - -All the above pass softfloat tests with the following exceptions: - -- fadd/fsub shows some differences in the handling of +0 / -0 results - when input operands differ in signs. -- the handling of underflow exceptions is slightly different. If a - result underflows before rounding, but becomes a normalised number - after rounding, we do not signal an underflow exception. - -Other operations which have been tested by basic assembly-only tests -are: - - - fcpy - - fabs - - fneg - - ftoui - - ftosiz - - ftouiz - -The combination operations have not been tested: - - - fmac - - fnmac - - fmsc - - fnmsc - - fnmul |
