hppa unwind entries

[Nick Hudson]

Hi,

Here's a test case that produces incorrect unwind entries on hpppa

$ cat foo.s
       	.text
        .export foo, entry
        .label foo
        .proc
        .callinfo frame=0
        .entry

	bv      %r0(%rp)
	 nop
	.exit
        .procend
        .size foo, .-foo
        .end
$ hppa--netbsd-as -o foo.o foo.s
$ hppa--netbsd-ld -Ttext 0x20000 -e foo -o foo foo.o
$ readelf -u foo

Unwind section '.PARISC.unwind' at offset 0x1008 contains 1 entries:

<foo+1000>: [0x21000-0x21004]

$

Note the "<foo+1000>"

It seems to me that the calculation of text_segment_base and data_segment_base 
are incorrect and here's a patch that address the problem by using the method 
ia64 SEGREL stuff is done.

Is this right? Is there a simpler way?

All help gratefully received.

Thanks,
Nick
