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
|
