Subject: [Bug target/23359] New: Many Solaris 10/x86 testsuite failures with native as: use of .word

Between 20050627 and 20050805, several C and C++ testcases begain to fail
on Solaris 10/x86 with the native as, e.g.

+FAIL: g++.old-deja/g++.brendan/crash63.C (test for excess errors)

Excess errors:
Assembler: crash63.C
	"/var/tmp//ccnloMW3.s", line 22 : Illegal mnemonic
	"/var/tmp//ccnloMW3.s", line 22 : Syntax error

Line 22 has

        .word   0x0b0f

which is from i386.md (trap).

This was introduced by this patch:

2005-07-21  Andrew Pinski  <pinskia@physics.uc.edu>

        * config/i386/i386.md (trap): Use "".word/t0x0b0f" instead of ud2.

http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01347.html

(Btw., the ChangeLog has two typos: double leading " and /t instead of \t)

One should be able to use .value instead (cf. ASM_SHORT in att.h, but
ASM_SHORT seems completely unused right now!?).  I've no idea how to do
this in the .md file, though.

Environment:
System: SunOS erebus 5.10 LAE_Preview i86pc i386 i86pc
Architecture: i86pc

	
host: i386-pc-solaris2.10
build: i386-pc-solaris2.10

How-To-Repeat:
Bootstrap mainline as above.
