2 Release notes for Linux Kernel VFP support code
3 ===============================================
9 This is the first release of the Linux Kernel VFP support code. It
10 provides support for the exceptions bounced from VFP hardware found
13 This release has been validated against the SoftFloat-2b library by
14 John R. Hauser using the TestFloat-2a test suite. Details of this
15 library and test suite can be found at:

19 The operations which have been tested with this package are:
33 All the above pass softfloat tests with the following exceptions:
35 - fadd/fsub shows some differences in the handling of +0 / -0 results
36 when input operands differ in signs.
37 - the handling of underflow exceptions is slightly different. If a
38 result underflows before rounding, but becomes a normalised number
39 after rounding, we do not signal an underflow exception.
41 Other operations which have been tested by basic assembly-only tests
51 The combination operations have not been tested:
