• Last-Minute_Requests_for_4.0.0

Introduction

• This page documents requests that have been made for last-minute changes to GCC 4.0.0. These changes will be considered only if the RM determines that there needs to be a second GCC 4.0.0 release candidate. Please do not make changes to this page without the permission of the RM.

GCC 4.0 RC2 Status

• Primary Platforms

• arm-none-elf
  • Julian Brown reports some FAILs here:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01301.html It is unknown if these are regressions, but the V3 failures reflect merely the fact that the !DejaGNU arm-sim.exp configuration doesn't configure remote downloads correctly. Other failures are primarily due to tests that use too much memory for the simulator, or which fail due to limitations in newlib.

• hppa2.0w-hp-hpux11.11
  • Joseph Myers reports no regressions:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01379.html

• i686-pc-linux-gnu
  • Haren Visavadia reports no problems in:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01308.html Joe Buck reports no problems in:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01307.html

• i386-unknown-freebsd
• mips-none-elf
  • Richard Sandiford reports no regressions in:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01331.html

• powerpc-ibm-aix5.2.0.0
• sparc-sun-solaris2.9
  • Eric Botcazou reports no problems.

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01135.html

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01302.html

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01300.html

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01299.html

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01298.html

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01297.html Joe Buck indicates a problem with Java and libiconv, but this is a known configury problem.

• x86_64-unknown-linux-gnu
  • Laurent Guerby reports no C or Ada problems in:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01307.html However, that does not include C++ results. Joe Buck reports only nested-function problems in:

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01333.html and indicates that these failures are not new on this machine.

  • Secondary Platforms
• powerpc-apple-darwin
  • Geoff Keating reports that the Java bootstrap fails. Andrew Haley reports here:

    http://gcc.gnu.org/ml/gcc/2005-04/msg01068.html that there is a bad interaction between the Java front end and dbxout.c. So, this problem probably only affects targets that use stabs. Mark Mitchell indicated that this problem is not release-critical.

• powerpc-unknown-linux-gnu
  • Andreas Tobler reports 1 FAIL (unknown if this is a regression):

    http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg01370.html

• i686-pc-cygwin
• ia64-unknown-linux-gnu
  • Jim Wilson comments that the problem shown in [gccbug: 20973] could cause problems on this platform when calling routines (such as those in GLIBC) that leave registers with NAT bits set.

Approved for 4.0.0

• [gccbug: 20991]

Patch Queue

• [gccbug: 20973]
  • Jim Wilson comments that this patch probably reflects a deeper problem which will effect Itanium.

GCC 4.0 RC1 Status

• Primary Platforms

• i386-unknown-freebsd

  • http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg00870.html Regressions are reported by Loren Rittle to be:

    gcc.c-torture/execute/ieee/copysign1.c execution,  -Os
