           Summary: i386-unknown-freebsd bootstrap comparison failure
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gerald@pfeifer.com


x86_64-unknown-freebsd seems to work, and with nobody seeing this on GNU/Linux
I am wondering whether this may be due to i386 (vs i586)?

I see the same on CentOS 5.6 x86 (i686-pc-linux-gnu) build from 2011/08/06
snapshot of gcc. Exactly the same error output.

Can you trigger this bug on linux (either x86_64 or i686) using following
configure string:

CC="gcc -m32" CXX="g++ -m32" <gcc-src>/configure i586-linux

We ran a reghunt of sorts and came up with the following results.

The first confirmed bootstrap comparison failure occurred after
revision 177265 was applied.

r177265 | uros | 2011-08-03 03:46:04 -0700 (Wed, 03 Aug 2011) | 9 lines

However, the builds before that revision terminated with a compilation
error in config/linux/affinity.c, which was fixed by this revision.
The compilation error was introduced by this commit:

r177194 | jakub | 2011-08-02 09:13:29 -0700 (Tue, 02 Aug 2011) | 238 lines
Merge from gomp-3_1-branch branch:

Thus, it seems that revision 177194 or a subsequent revision preceding
177265 introduced the bootstrap comparison failure on i386 (we ran our tests
on i686 running CentOS).

On FC14 x86_64, after installing the i686 libraries for
{gmp,libmpc,mpfr}{,-devel}, built against trunk
revision 177922 (last changed 2011-08-19 17:18:07 PDT),
the build completed *without* error.

I'll try trunk revision r177218 (reported by Gerald) for completeness,
and post the results.

I believe the difference may be i686 versus i486:

config/i386/freesd.h has #define SUBTARGET32_DEFAULT_CPU "i486" and does
not use a different default otherwise.

Putting binutils 2.21.1 in PATH before the system versions of these tools,
which
are binutils 2.17.50 based, avoids the issue on FreeBSD 9/i386.

Let's adjust the summary, the problem isn't visible if you have CFI directives.

On the i686 CentOS release 5.6 system that we ran our tests on,
the installed binutils package is: binutils-2.17.50.0.6-14.el5.
Thus, confirming Gerald's observation.

vs.

The problem is that when add_cfis_to_fde is creating NOTE_INSN_CFI_LABEL notes,
it doesn't ignore NOTE_INSN_VAR_LOCATION and NOTE_INSN_CALL_ARG_LOCATION in
between the NOTE_INSN_CFI notes, so with -fvar-tracking-assignments we generate
one extra label because the NOTE_INSN_CFI notes aren't consecutive, there is
one
NOTE_INSN_VAR_LOCATION in between.  And, apparently gas for some reason doesn't
optimize away completely DW_CFA_advance_loc* if it advances by 0 (guess
something to fix).

Here is an untested fix.  It would be enough to skip over just the
NOTE_INSN_VAR_LOCATION and NOTE_INSN_CALL_ARG_LOCATION notes, but if gas
doesn't optimize zero length advances, I'd say we should skip over all non-real
insns.

This patch fixes bootstrap on i386-unknown-freebsd9.0 and test results
(cf. http://gcc.gnu.org/ml/gcc-testresults/2011-09/msg01121.html ) appear
to be in the normal range.
