[Bug bootstrap/31523] New: bootstrap xgcc internal compiler error (using -O3)

[anirkko at insel dot ch]

Bootstrap of gcc-4.1.2 failed with an internal compiler error
("Please submit a full bug report") from ./gcc/xgcc when compiling
libstdc++-v3/libsupc++/del_op.cc, using gcc-3.4.3 as the bootstrap
compiler on sparc-sun-solaris2.6 with following configure options
and bootstrap flags (below), producing the follwing output (further
below), with the follwing -save-temps generated .ii file (furthest
below):

setenv CONFIG_SHELL /bin/ksh

Can you try without setting the CFLAGS, etc. because what might be happening is
the base compiler miscompiling the new compiler?

Do really have a SuperSPARC?  If no, remove the -mcpu=supersparc option, it is
totally untested these days.  If so, I'd suggest to stick with a 3.x compiler
on this presumably old machine.

Tried something slightly different: because this happened in C++, I
bootstrapped
gcc-4.1.2 with lang=C,ada and it worked fine, error-free, including passing the
stage2 comparison passed. The resulting gcc-4.1.2 should now be enough to use
as base compiler to build everything else, including c++.
When doing this (same flags and options), I got exactly the same internal
compiler error again. Thus, both the base compiler gcc-3.4.3 and gcc-4.1.2 lead
to the same error.
Will try next without -O3 and other flags to see if one of these generate the
error.

Several machines from SuperSPARC 110 MHz to multi-CPU UltraSPARC-III 1.3 GHz,
and even the SuperSPARCs still work better than the average PC. Some old SBUS
hardware only works with the old machines. I like to have the same gcc binary
running on all machines, which will also produce binaries that will run on all
machines from Solaris 2.6 to Solaris 10.

Most likely I'd say.  I happen to regularly bootstrap GCC 4.1.x with GCC 3.4.3
and the default options on Solaris 2.5.1 and 2.6 UltraSPARC machines and this
works flawlessly:

The bootstrap works fine with all flags equal to '-O2'
Still worrysome, because somewhere in the installation instructions, it is
recommended to bootstrap the compiler with the flags one intends to later
use it with.
Sometime, will try to find out whether the offending flag is -O3 or
-mcpu=supersparc.
Does it mean the offending flag is broken and should never be used at all?

Great, thanks for the confirmation.

Please point me to this and I'll immediately propose to delete it.  99% of
the testing of the compiler is done with the default bootstrap settings.

-mcpu=supersparc is totally untested these days so bugs can be expected, yes.

It is in the main directory, file FAQ, section "Optimizing the compiler
itself":
   If  you  want to test a particular optimization option, it's useful to
   try  bootstrapping  the  compiler  with  that  option  turned  on.
But please don't let this be removed, because

1) I find the suggestion  useful, and it seems to somewhat parallel the reason
why you want the compiler bootstrap itself through all stages in the first
place: to make sure it can compile itself. Likewise, if it can compile
itself reproducibly through the bootstrap using different options, you have
made sure these options are pretty well tested for real code by the time you
have the compiler finished

2) You closed this bug on the premises that -mcpu=supersparc is the culprit.
Well, it isn't: I now bootstrapped with '-O2 -mcpu=supersparc' and everything
went fine!
Therefore, I still think there is a bug in -O3. (alternatively, in the
combination of the two). Would you consider reopening this bug if it was -O3?
(In this case, I might re-run the bootstrap with only '-O3', next weekend).

OK, but note that it's quite different from what you said.  First, it's not
"recommended", it's "useful to try".  Second, it's only for *testing* the
option, not for production use.

OK, that makes sense.

Yes, I'm going to reopen it, but I'm not sure someone will tackle it.

Testing several combinations, it turns out the bug is indeed in '-O3' alone:
   Machine: Ultrasparc
   Base compiler: gcc-4.1.2  (bootstrapped with -O2)
Using this setup, bootstrapping
   -works with '-O2'
   -works with '-O2 -mcpu=supersparc -no-app-regs'
   -FAILS with '-O3'
   -FAILS with '-O3 -mcpu=supersparc -no-app-regs'
    (exactly same ICE as reported in the first place, above)
Thus, it is reproduced several times, both with gcc-3.4.3 and gcc-4.1.2 itself
as base compiler.
Would it help to individually test the various sub-options that -O3
switches on? If you could give me these sub-options ranked according
to 'suspectedness' then I could run the script to test them one by one.
Reason: if the responsible sub-option is identified, it could be discarded from
the -O3 defaults for being tested and found unsafe, even if no one has time
to tackle/mend it.

The culprit is -finline-functions:

The gcc man page says -O3 adds only 3 additional options. My bootstrapping
script tells me the bug is in -finline-functions. Base compiler = gcc-4.1.2
(itself built without error using -O2), target compiler also gcc-4.1.2, when
using -finline-functions as bootflags, the bootstrapped xgcc fails with
an ICE at exactly the same place as originally reported above.

Should -finline-functions be excluded from the default -O3 options?
(until mended. If it can't be trusted building the comopiler, can it be
trusted for anything else?)

keywords added:
  build (problem occurs during bootstrap)
  wrong-code (compiles and links xgcc, but then xgcc fails later)
  ice-on-valid-code (the xgcc above fails with ICE during the build)

(In addition to comment #12)

PS: The above was done on sparcv9 (UltraSparc-III)
    with Solaris 8. Thus, the bug is confirmed on
    several machines with several versions of Solaris
    and several versions of binutils (2.14 and 2.17)

-finline-functions is very likely not the root problem, it must uncover some
latent bug elsewhere.  I'm going to try to reproduce the failure.

[Bug rtl-optimization/31523] bootstrap failure with -O2 -finline-functions

[ebotcazou at gcc dot gnu dot org]

------- Comment #17 from ebotcazou at gcc dot gnu dot org  2007-05-10 12:16 -------
Reduced C++ testcase:

typedef enum { _B_FALSE, _B_TRUE } boolean_t;
typedef union { int i; } u;

cp/lex.c:make_aggr_type is miscompiled when cxx_make_type is inlined into it.

Amazingly enough, this is the same problem as PR rtl-optimization/31691.
