SNV 4.5.2 can't parse 2.4.0 linuxppc kernel

SNV 4.5.2 can't parse 2.4.0 linuxppc kernel

[Lonnie VanZandt]

Source Navigator is having problems parsing the PPC 2.4.0 kernel
sources. The first problem is a "b ." operation in
arch/parisc/kernel//hpmc.S. After commenting out that line, parsing
hangs again on another file. I haven't looked at that second fault yet.
One must sigkill snav to get back control.

Unless you've not rewritten a PPC assembly parser, you going to
have a hard time parsering PPC instructions.

You should still be able to look at all the non PPC assembly files.

If you want the PPC assembly files you have to write a PPC parser.

If you want to write a assembly parser, you should look at
the examples in the Source-Navigator code base.

I'm not surprised -- S-N doesn't know how to parse HP PA-RISC assembly.

Can you identify the troublesome second file?  Does it cause a problem in a
project on its own?

Let's ignore my emails today.

There really is a PPC parser.

I suspected so since it had no problems with 2.2.* with PPC...

arch/arm/mach-sa1100/arch.c causes the Project Scanner to simply hang. I
took the parisc directories out of hierarchy so now this file is the first
hang. It takes a sigkill to get control back and unfortunately the core
offers no clue since it is symbolless.

It would be helpful if snav rather than hanging when it encountered a
problem file would flag the file, skip it, and go on...

We ship a powerpc parser with Source-Navigator. It might be choking on
x86 assembler, however.

The first problem was with PA-RISC assembly. I didn't see anything unusual
that would have caused the second hang...
