[Linux-ia64] parport for ia64

Hi,

I had to add the following file as include/asm-ia64/parport.h to compile
the parport modules on ia64.

(See attached file: parport.h.gz)

But when compiling with default optimizations, I get the following:

-----------
make[2]: Entering directory `/usr/src/linux-2.4.0-test6/drivers/parport'
gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -g -O2
-fomit-frame-pointer -pipe  -Wa,-x -ffixed-r13
-mfixed-range=f10-f15,f32-f127 -funwind-tables -fno-strict-aliasing
-DMODULE   -DEXPORT_SYMTAB -c parport_pc.c
parport_pc.c: In function `cleanup_module':

parport_pc.c: In function `parport_pc_read_status':
parport_pc.c:2719: Internal compiler error in
`add_abstract_origin_attribute', at dwarf2out.c:7532
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/faq.html#bugreport> for
instructions.
make[2]: *** [parport_pc.o] Error 1
-----------

When I removed the -O2 from the compile flags, it compiled fine.

Kernel: linux-2.4.0-test6-ia64-000811
gcc: gcc version 2.9-ia64-000216-final

regards,
chris

	`add_abstract_origin_attribute', at dwarf2out.c:7532

This testcase works OK with the current compiler development sources.

This was fixed by a gcc/dwarf2out.c patch on 2000-04-25.  However, I know
that patch only works if a few other following patches are also used, and
I don't know what the complete set of necessary patches is, so this doesn't
seem worthwhile to try to fix in the February compiler.

I'd suggest using a workaround until a newer compiler is ready.  Compiling
without -g will make the problem go away.  Also, getting rid of the inline
version of the parport_pc_read_status function will solve the problem.
