[parisc-linux] New glibc on 715/75

[Richard Hirst]

I am trying the glibc etc from newcompilers-20010314 on my 715/75.
It seems anything that is dynamically linked hangs on exit.

I am booting with init=/bin/sash, and have static and dynamic
versions of hello-world (in C, not C++), and of gdb.

I can run the static programs ok, but if I run the dynamic hello-world
it outputs HelloWorld and then goes to sleep.  Console still echoes,
but I don't get the sash prompt back.

This isn't a particularly new problem - I havn't had a working 715/75
root fs since the attempt to part-fix libpthread.

Hangs in this loop:

0x40014150 <__hppa_make_fptr+56>:       ldw 5f0(sr0,r1),r1
0x40014154 <__hppa_make_fptr+60>:       ldcw  0(sr0,r1),r1
0x40014158 <__hppa_make_fptr+64>:       cmpib,= 0,r1,0x40014150 <__hppa_make_fptr+56>
0x4001415c <__hppa_make_fptr+68>:       addil 0,r19,%r1

r19 = 4001a930.

For a good run on the B180, I get in to this code with the
same r19.  r1=r19, r1+0x5f0=0x4001af20

0x4001af20 <errno+1848>:        0x4001a7c8

0x4001a7c8 <__hppa_fptr_lock>:  0x00000001


Presumably on the 715/75 __hppa_fptr_lock is zero.

__hppa_make_fptr() is in sysdeps/hppa/dl-fptr.c

Arggh!  That's not 16 byte aligned.
