The bootstrap hardly runs for a few minutes and then I get an ICE.

The _exact_ same ./configure commands work on gcc 4.2.0/1 (last few weeks).
I have saved a "make" screen output log (and the whole build directory).

No rush, I'll play with 4.2.1 while I wait to see if this clears up.

------- Comment #1 from rob1weld at aol dot com  2007-05-21 19:09 -------
I did some more testing on this issue. I started pulling off configure option a
half dozen at a time.

1st I removed:
--enable-initfini-array --enable-__cxa_atexit --enable-threads=posix
--enable-decimal-float --with-long-double-128 --with-tls

Next I removed:
--enable-objc-gc --enable-concept-checks --enable-libstdcxx-debug
--enable-static --enable-shared --enable-version-specific-runtime-libs
--enable-gc-debug

Then I removed:
--enable-libssp --enable-libmudflap --enable-libgomp --enable-nls
--with-included-gettext --enable-debug --enable-java-gc=boehm --with-x
--x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib
--enable-java-awt=gtk,xlib --enable-gtk-cairo --enable-qt-peer --enable-xmlj
--enable-gconf-peer --enable-tool-wrappers --with-gjdoc
--enable-portable-native-sync --enable-libgcj-multifile --with-stabs
--enable-hash-synchronization --enable-interpreter --with-system-zlib
--enable-libada


It still broke each time in the _exact_ same place. Finally I removed _ALL_
options and simply used "./configure". A grep of the Makefile's
BUILD_CONFIGARGS says: '--enable-languages=c,c++,fortran,java,objc' which are
not enough for what I prefer - but now it builds I can add some more options
back in.


So now my xgcc says this:

#gcc/xgcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: /root/downloads/gcc-4_3-trunk/configure
Thread model: posix
gcc version 4.3.0 20070521 (experimental)


The make of gcc has now passed the point where the prior ICE occurred. I did a
"diff -q" of the ICE'd build directory and the (so far) successful directory
and came up with this output (hand-edited output of diff):

Since there are very few differences in the gcc-4_3-build-ICE/gcc/* files and
the ".o" (and executable files) are _identical_ it is my opinion that the gcc
executable itself is _probably_ not at fault. The same can be said for the
"intl" directory.

The directories with _many_ differences are "zlib" (probably not at fault) and
"libiberty", which is where the problem _might_ be.

I will try some more to narrow this down by adding back more options and
rebuilding repeatedly.

[Bug middle-end/32024] ICE - libgcc2.c:557: internal compiler error: in fold_checksum_tree, at fold-const.c:12652

[rob1weld at aol dot com]

------- Comment #2 from rob1weld at aol dot com  2007-05-21 21:05 -------
The BUG is somewhere in here:

I put back ALL my origonal (lengthy) configure options but left off the
checking. It gets past the ICE. That is not good though...

Situation A): The checker is working fine and the code produced is incorrect
and this is being caught by the checker.

Situation B): The checker is incorrect and the code produced is OK, the checker
is wrongly complaining about code that is OK.

I check back in a day or two ...

------- Comment #5 from rob1weld at aol dot com  2007-05-22 16:02 -------
Thanks for confirming, Richard. It works on 4.2.0/1 and I've enclosed notes in
the prior message that _probably_ explain why it is failing.

In addition I just did a build (one day newer version) _without_ "fold" and it
still halted the make and trigger a GNAT BUG in verify_flow_info.

If the bootstrap is that touchy then we won't be getting many good compiles
finishing (and test results submitted, and bugs fixed).

Yesterday it worked, today I added
"--enable-stage1-checking=assert,gc,misc,rtl,rtlflag,runtime,tree" and it
broke.

---

I'm placing this here because I am reasonably certain that it is related to the 
problems with the "fold-const.c" after examining the code.

Since _I_ did not add the "flow" flag the "verify_flow_info failed" error is a
result of the existing flow checking and nothing that I added.



I was able to complete the build on 4.3.0 _yesterday_ (without the other
checking ebabled) using my usual HUGE number of options, (everything).

[Bug middle-end/32024] ICE - libgcc2.c:557: internal compiler error: in fold_checksum_tree, at fold-const.c:12652

[rob1weld at aol dot com]

------- Comment #6 from rob1weld at aol dot com  2007-05-24 06:41 -------
"make profiledbootstrap" is broken.

Newest compile uses
"--enable-stage1-checking=assert,gc,misc,rtl,rtlflag,runtime" since both "fold"
and "tree" have some issues.

I hope the two different spots help narrow down the one place where "fold" is
broken (if that is what the problem is).

So, chrec_convert_1() is sending ssa_name into fold_convert().

------- Comment #15 from rob1weld at aol dot com  2007-06-24 02:17 -------
I origonally reported "The bootstrap hardly runs for a few minutes and then I
get an ICE." That is no longer the case. I am making gcc version 4.3.0
20070623.

I'm 4 hours into the make (my build is made using
"--enable-stage1-checking=assert,df,fold,gc,misc,rtl,rtlflag,runtime,tree"), it
is passed all the stages and into the libraries now.

_This_ bug report was marked as "RESOLVED DUPLICATE" of 20623 (which is filed
against 4.1.0 for HTB x86_64-unknown-linux-gnu, while _this_ report is for
4.3.0 HTB i686-pc-linux-gnu - the kind of errors are different too).

Since _this_ report is marked "RESOLVED DUPLICATE" _I_ can not change it to
"RESOLVED FIXED", if someone else who is able would wish to do so that is OK by
me. I do not know that 20623 is fixed and no one has marked it as such.
