Package: gcc
Version: 1:2.95.3-7
Severity: important
Maybe I've been working too hard, but this gcc seems to get this wrong
with -O2:
void gunc(unsigned a, unsigned b)
{
}
unsigned func(unsigned a, unsigned b)
{
long long x = 0;
gunc(a, b);
return (x + 1) * a * b;
}
int main()
{
unsigned a, b;
a = 1;
b = 1;
return func(a, b);
}

Subject: fixed bugs in gcc-3.0 (3.0.ds6-0pre010526)
X-Mailer: VM 6.43 under 20.4 "Emerald" XEmacs Lucid
Message-ID: <15121.31254.719834.751026@bolero>
Delivered-To: 97030-done@bugs.debian.org
gcc-3.0 (3.0.ds6-0pre010526) unstable; urgency=high
* Urgency "high" for replacing the gcc-3.0 snapshots in testing, which
now are incompatile due to the changed ABIs.
* Upstream begins tagging with "gcc-3_0_pre_2001mmdd".
* Tighten dependencies to install only binary packages derived from
one source (#98851). Tighten libc6-dev dependency to match libc6.
gcc-3.0 (3.0.ds6-0pre010525) unstable; urgency=low
* ATTENTION: The ABI (exception handling) changed. No upgrade path from
earlier snapshots (you had been warned in the postinst ...)
Closing #93597, #94576, #96448, #96461.
You have to rebuild
* HELP is appreciated for scanning the Debian BTS and sending followups
to bug reports!!!
* Should we name debian gcc uploads? What about a "still seeking
g++ maintainer" upload?
* Fixed in gcc-3.0: #97030
* Update patches for recent (010525) CVS sources.
* Make check depend on build target (fakeroot problmes).
* debian/rules.d/binary-libgcc.mk: new file, build first.
* Free memory detection on the hurd for running the testsuite.
* Update debhelper build dependency.
* libstdc++-doc: Include doxygen generated docs.
* Fix boring packaging bugs, too tired for appropriate changelogs ...
#93343, #96348, #96262, #97134, #97905, #96451, #95812, #93157
* Fixed bugs: #87000.
