Subject:   NPX configuration after exec()
Message-ID:  <98Aug10.070026est.40495@border.alcanet.com.au>

next in thread | raw e-mail | index | archive | help
The NPX (x87) is initialised with a configuration word of 0x1272
(sys/i386/include/npx.h __BDE_NPXCW__).  The comment associated with
this states:
 * Later I will want the IEEE default of all exceptions masked.  See the
 * 0.0 math manpage for why this is better.  The 0.1 math manpage is empty.

Whilst I'm uncertain of the references to 0.0 and 0.1, math(3M) does
include some comments which imply that libm is designed to function
correctly with all exceptions masked.

Are there any plans to change the configuration word to 0x127f as implied
in this comment?
