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

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