Subject: Re:  [alphaev5-dec-osf5.0] gcc-3.1 build fails with internal error

I tried to compile gcc-3.3 now, but still without success. This time the
failure shows up on a different location. Here are last few lines of the gmake
output:

The

For me it's not clear why the
function fancy_abort() gets called (with obviously invalid parameters on the
stack). So it seems that either the stage1 gcc or some other component (osf1
assembler/linker) is generating invalid code.

As with previous versions of
gcc I was able to build the compiler successfully with BOOT_CFLAGS="-g -O
-fno-reorder-blocks"

Cheers,
Rainer

Okay, so this is the same problem as in PR 9899. Supposedly, this problem is 
fixed with mainline. If someone could figure out which patch in fact fixed 
this, then it's probable the fix can be applied to the 3.3 branch as well.

I tried to find out when this bug was fixed in the main line by compiling cvs versions from 
various dates (cvs update -D ....). Here is what I've found out: 
 
2003-03-06: compiling fails with the genattrtab bug (like most version before this date). 
 
2003-03-07: failure during compilation of libstdc++: xgcc: Internal error: Segmentation fault 
(program cc1plus) 
 
2003-03-08: like 2003-03-07 
 
2003-03-09: success 
 
So it seems the bug has been corrected between March 6th and 8th. 
Maybe this info helps you to find the correct patch for backporting to the 3.3 branch.

Wow, thanks for narrowing this down! I took a look at the gcc-cvs mailing list archives but didn't 
seen anything particularly obvious. The things that look possibly connected are Richard Kenner's 
patch to alpha.md and others, and Roger's patch for emit-rtl.c. Oh, and this patch, claims to be 
Itanium only, but seems to deal exactly with the issue of block reording (and deals with generic 
code in the scheduler):

Move to target to 3.3.2 as this only effects 3.3 as the mainline has been fixed.  The 
comments neared it down to the day where it was fixed but nothing has come about after 
that.

Closing as fixed on the mainlne because it works there and there is most likely not going 
to be a 3.3.3 release.
