[llvm-testresults] Broken buildbot: llvm-gcc-i386-linux-selfhost

Fri Sep 24 10:19:52 PDT 2010

Hi,

The llvm-gcc-i386-linux-selfhost is currently broken in test.llvm.stage2, it looks like FileCheck is being miscompiled.

There has been some noise because of other failures, so the commit breaking this bot wasn't caught.

This is the last good build:

http://google1.osuosl.org:8011/builders/llvm-gcc-i386-linux-selfhost/builds/45 (r114628)

This is the first build to fail in the way it is currently failing:

http://google1.osuosl.org:8011/builders/llvm-gcc-i386-linux-selfhost/builds/55 (r114684)

I suspect Rafael is the culprit since this is only happening on Linux, but Evan is a candidate as well.

These are the possible offending commits:

    Revert 114634 for now since buildbot claim it broke Clang self-hosting. I doubt it but it's possible it's exposing another bug somewhere.

    Clean up the 'trap' instruction printing a bit. Non-Darwin assemblers don't
    (yet) recognize the 'trap' mnemonic, so we use .short/.long to emit the
    opcode directly. On Darwin, however, we do want the mnemonic for more
    readable assembly code and better disassembly.

    Adjust the .td file to use the 'trap' mnemonic and handle using the binutils
    workaround in the assembly printer. Also tweak the formatting of the opcode
    values to make them consistent between the MC printer and the old printer.

    Represent relocations against local symbols as relocations against the section
    they are in. Both ways should be equivalent, but gas produces relocations
    against the section.

    Fix llvm-extract so that it changes the linkage of all GlobalValues to
    "external" even when doing lazy bitcode loading.  This was broken because
    a function that is not materialized fails the !isDeclaration() test.

    If there are multiple unconditional branches terminating a block, eliminate all
    but the first one. Those will never be executed. There was logic to do this
    but it was faulty.

    SDISel should not optimize a unconditional branch following a conditional branch
    when the unconditional branch destination is the fallthrough block. The
    canonicalization makes it easier to allow optimizations on DAGs to invert
    conditional branches. The branch folding pass (and AnalyzeBranch) will clean up
    the unnecessary unconditional branches later.

    This is one of the patches leading up to disabling codegen prepare critical edge
    splitting.
