[parisc-linux] Internal compiler error

[Grant Grundler]

Dave (dhd),
Since you expressed an interest in compiler bugs:

...

make[3]: Leaving directory `/linux/grundler/linux-2.3/drivers/gsc'
...

I'm changing code in several files in order to build an I/O tree of hp_devices
much like pci does...the problem above was due to one of my changes:

...
STATIC struct list_head dino_list;
...

        list_add(&dino_dev->dino_hba.hba_dev->global_list, dino_list);


Missing a '&' in front of dino_list and the compiler really
didn't like that. I don't have a big problem with the compiler
"oops"ing here since it correctly identified the problem.

cheers,
grant

Grant,

Is this patch in your tree?

2000-06-26  J. David Anglin  <dave@hiauly1.hia.nrc.ca>

        * c-typeck.c (digest_init): Return error_mark_node node when
	TREE_TYPE (init)  == error_mark_node.

The problem looks similar to the one the above patch addressed.

I couldn't find "Return error_mark_node node" string in gcc/gcc/c-typeck.c.

I'm using whatever we have in binutils-2.10 and gcc CVS.
I just rebuilt yesterday (7/11/2000) after dhd was done with
some recent modifications.

thanks,
grant

that's in our tree;

2000-06-26  J. David Anglin  <dave@hiauly1.hia.nrc.ca>

        * c-typeck.c (digest_init): Return error_mark_node node when
        TREE_TYPE (init)  == error_mark_node.

is in gcc/gcc/ChangeLog.  The last comment which isn't ours in ChangeLog
is dated 2000-07-07.  any changes since then which look even remotely
relevant?

Not that I am aware of.

There is a patch related to the alignment of fields that is not installed
because of portability concerns.  Alignments greater than 16 bytes are
not done correctly and may cause the compiler to abort due to a divide
by zero.  This may be important for the linux port.

Wrong search pattern.  The patched code in digest_init looks like

  if (type == error_mark_node
      || init == error_mark_node
      || TREE_TYPE (init)  == error_mark_node)
    return error_mark_node;

This fixed a similar problem where a missing declaration caused the
compiler to crash or produce the tree checking error that you got.
