-Release notes for Linux Kernel VFP support code
------------------------------------------------
-
-Date: 20 May 2004
-Author: Russell King
-
-This is the first release of the Linux Kernel VFP support code. 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
