It is for Linux kernel next-20130828 version.

and for the latest Linux kernel, h8/300 has been removed.

That means: gcc-4.8.0 has no this issue, only 4.9.0 has (and in my memory,
gcc-4.7.4 may also has this issue, but I am not quite sure).

I put .i file for fs/namei.c which need "bzip2 -d" to decompress.

Reduced testcase.  Appears to be blowing up in the dwarf2 bits.

Compile with -Os -mint32 -mh -fomit-frame-pointer -g

typedef _Bool bool;
typedef unsigned short umode_t;
enum {
 false = 0,
 true = 1
};
struct dentry {
 struct inode *d_inode;
};
struct path {
 struct dentry *dentry;
};
extern int vfs_create(struct inode *, struct dentry *, umode_t, bool);


long SYSC_mknodat(int dfd, const char * filename, umode_t mode, unsigned dev)
{
 struct dentry *dentry;
 struct path path;
 int error;
 unsigned int lookup_flags = 0;
 switch (mode & 00170000) {
  case 0: case 0100000:
   error = vfs_create(path.dentry->d_inode,dentry,mode,true);
   break;
  case 0020000: case 0060000:
   error = vfs_mknod(path.dentry->d_inode,dentry,mode, new_decode_dev(dev));
   break;
 }
}

Created attachment 30821
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30821&action=edit
some simple modification based on the reduced .c file.

After learning from what you have done, and give a little additional trying, it
seems we can focus on the new_devcode_dev().

  If it is not defined or defined as a simple inline function, can cause issue.

  If use normal parameter (not inline function), it will be OK.

  If add/del one parameter before new_devcode_dev(), it also be OK.

Please check the attachment for details.


Hmm... next, is it a suitable/correct way to debug gcc-4.9.0 (can cause issue)
and gcc-4.8.0 (no issue) for it with gdb, and comparing them? (I am just trying
in this way)

Thanks.

--- Comment #8 from Chen Gang <gang.chen at asianux dot com> ---
For gcc-4.9.0, I got summary trace for it (call stack for cc1, how many the
related loopings during calling flow), hope it may be a little useful. (I will
do the same thing for gcc-4.8.0, and compare them).

And it seems: gdb can not print the variables' value when "g++ -g -Wall
-static-libstdc++ -static-libgcc" which is effect with cc1 and xgcc.

If can let gdb print the vaiables' value, life will be a little easier (don't
need dump the related variables' values mannually).

Welcome any additional suggestions or completions.

Issue is within xgcc, can exclude cc1 by comparing the summary log between
gcc-4.8.0 and gcc-4.9.0.

By comparing the summary log between gcc-4.8.0 and gcc-4.9.0, the issue is
within xgcc, we can exclude cc1.

The attachment contents 3 files.

  err.diff: the gcc-4.9.0 summary log.
  correct.diff: the gcc-4.8.0 summary log.
  info.diff: my modification for gcc-4.9.0, so can print the related summary
log
               (the same modification for gcc-4.8.0)

I will continue to analyzing the details within xgcc, and also print more
related varaibles for analyzing.


Welcome any additional suggestions and completions, thanks.

(sorry, it is cc1 issue) It is the related command line for cc1 and the summary
work flow for gcc-4.8.0 and gcc-4.9.0

Oh, sorry, the comments #9 is obsoleted, it is not caused by xgcc (although
their work flow are different with each other), our issue is cc1 issue.

The attachment is the related command line for cc1 and the summary call flow
for gcc-4.8.0 and gcc-4.9.0.

I will continue to analyze the first different between them.

Welcome any suggestions and completions, thanks.

It seems, I am really really a newbie !!

1. after append "-gstabs+", can let gdb work well.

2. can use the internal dump_file (dump_start/dump_end) to analyze all
information (although I still don't know how to use it now).

3. that means: what I have done above is almost all 'spam'.  :-(


I will continue trying tomorrow.

For gcc version 5.0.0 20150109 (experimental) (GCC), can not find this issue
again. So at present, we can close it.
