PATCH: Update information for FreeBSD versions and architectures #1

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

According to Nick Hilliard on a FreeBSD mailing list and as confirmed
by my own study of the CVS log of /usr/src/sys/i386/include/npx.h and
my own recent upgrade to FreeBSD 4.2-STABLE: by default, IEEE floating
point math support provided by the kernel is suppose to work like
other gcc platforms and has in every shipped version of FreeBSD/i386
4.X.  We have no expectation to regress on this point in later
versions.  In particular, these tests all pass now on FreeBSD/i386
4.2-STABLE:

XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -O0 
XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -O1 
XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -O2 
XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -O3 -fomit-frame-pointer 
XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -O3 -g 
XPASS: gcc.c-torture/execute/ieee/mzero2.c execution,  -Os 
XPASS: gcc.c-torture/execute/ieee/rbug.c execution,  -O3 -fomit-frame-pointer 
XPASS: gcc.c-torture/execute/ieee/rbug.c execution,  -O3 -g 

A patch is provided to remark exactly which versions of FreeBSD are
known to fail those tests due to a different configuration.  With the
patch, these test (which reported XFAIL) now report as failing:

FAIL: gcc.c-torture/execute/ieee/rbug.c execution,  -O0 
FAIL: gcc.c-torture/execute/ieee/rbug.c execution,  -O1 
FAIL: gcc.c-torture/execute/ieee/rbug.c execution,  -O2 
FAIL: gcc.c-torture/execute/ieee/rbug.c execution,  -Os 

This appears to be a bonified issues to resolve.

Tested on i386-*-freebsd4.2 and alpha-*-freebsd4.2 by rerunning 'make
check-gcc' in an already bootstrapped tree.  As well, the exact regex
change was tested `by hand' in tclsh since I don't know TCL that well.

I believe that this patch is non-controversial and better expresses
the expected state of things on FreeBSD/i386.

Loren

	* gcc.c-torture/execute/ieee/mzero2.x: Adjust statement of
	where a failure is expected.
	* gcc.c-torture/execute/ieee/rbug.x: Likewise.
