 Hi all,
 
 the testcase in this PR is confirmed to still fail as reported on both  
 3.3 branch and mainline (20030506 using powerpc-apple-darwin6.5 x  
 hppa-linux cross compiler). It appears to be a generic PA bug as it  
 also fails on hppa1.1-hp-hpux10.20 and hppa-2.0w-hp-hpux11.00 triplets  
 while compiling successfully on c4x and powerpc-apple-darwin6.5.

 Hi all,
 
 this is to confirm that with a gcc 3.3 cvs darwin x
 hppa-linux cross compiler, the problem in this PR
 still occurs. Compiling the testcase with -fPIC
 yields:
 
 junk.i: In function `bad':
 junk.i:14: error: unrecognizable insn:
 (insn 24 23 25 2 0x0 (set (reg/f:SI 102)
         (plus:SI (reg:SI 19 %r19)
             (high:SI (symbol_ref/v:SI ("@tramp_r")))))
 -1 (nil)
     (nil))
 junk.i:14: internal compiler error: in extract_insn,
 at recog.c:2175
 Please submit a full bug report,
 with preprocessed source if appropriate.
 See <URL:http://gcc.gnu.org/bugs.html> for
 instructions.
 
 Cheers,
 
 Dara
