m68k-hp problem

[Hans Cappelle <cappelle at imec dot be>]

Hi,

I compiled a m68k-hp cross compiler with
the egcs-19981101 snapshot. To my surprise
it fails in dwarf2out.c, even for
"trivial" code examples and if no debugging
info is requested.
 
The cross compiler has following characteristics :

GNU C++ version egcs-2.92.18 19981101 (gcc2 ss-980609 experimental)
(m68k-hp) compiled by GNU C version 2.7.2.2.
(on a hpux PA1.1 system -> this is probably not relevant for
 the bug)

(to reproduce : ./configure --target=m68k-hp)

Simple examples as :

int foo (int a) {
  a++;
  return a;
}

fail with following error message

dwarf2out.c:1695: Internal compiler error in function
                  output_call_frame_info

		  		  
The dwarf2out.c PROBLEM line executes the ASM_OUTPUT_ALIGN macro,
which is defined in m68k.h but redefined in  various .h
files in the m68k config directory. I expect the definition
in hp320.h causes the bug. 

Possibly other m68k configurations are affected too.



best regards,
