11 years agoThis patch addresses an incorrect transformation in the DAG combiner.
Bill Schmidt [Mon, 14 Jan 2013 22:04:38 +0000 (22:04 +0000)]
This patch addresses an incorrect transformation in the DAG combiner.

The included test case is derived from one of the GCC compatibility tests.
The problem arises after the selection DAG has been converted to type-legalized
form.  The combiner first sees a 64-bit load that can be converted into a
pre-increment form.  The original load feeds into a SRL that isolates the
upper 32 bits of the loaded doubleword.  This looks like an opportunity for
DAGCombiner::ReduceLoadWidth() to replace the 64-bit load with a 32-bit load.

However, this transformation is not valid, as the replacement load is not
a pre-increment load.  The pre-increment load produces an extra result,
which feeds a subsequent add instruction.  The replacement load only has
one result value, and this value is propagated to all uses of the pre-
increment load, including the add.  Because the add is looking for the
second result value as its operand, it ends up attempting to add a constant
to a token chain, resulting in a crash.

So the patch simply disables this transformation for any load with more than
two result values.

Eli Bendersky [Mon, 14 Jan 2013 19:04:57 +0000 (19:04 +0000)]
Expose an InitToTextSection through MCStreamer.

The aim of this patch is to fix the following piece of code in the
platform-independent AsmParser:

void AsmParser::CheckForValidSection() {
  if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
    TokError("expected section directive before assembly directive");
    Out.SwitchSection(Ctx.getMachOSection(
                        "__TEXT", "__text",
                        MCSectionMachO::S_ATTR_PURE_INSTRUCTIONS,
                        0, SectionKind::getText()));
  }
}

This was added for the "-n" option of llvm-mc.

The proposed fix adds another virtual method to MCStreamer, called
InitToTextSection. Conceptually, it's similar to the existing
InitSections which initializes all common sections and switches to
text. The new method is implemented by each platform streamer in a way
that it sees fit. So AsmParser can now do this:

void AsmParser::CheckForValidSection() {
  if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) {
    TokError("expected section directive before assembly directive");
    Out.InitToTextSection();
  }
}

Which is much more reasonable.

Michael Gottesman [Sat, 12 Jan 2013 01:25:15 +0000 (01:25 +0000)]
Fixed a bug where we were tail calling objc_autorelease causing an object to not be placed into an autorelease pool.

The reason that this occurs is that tail calling objc_autorelease eventually
tail calls -[NSObject autorelease] which supports fast autorelease. This can
cause us to violate the semantic gaurantees of __autoreleasing variables that
assignment to an __autoreleasing variables always yields an object that is
placed into the innermost autorelease pool.

The fix included in this patch works by:

1. In the peephole optimization function OptimizeIndividualFunctions, always
remove tail call from objc_autorelease.
2. Whenever we convert to/from an objc_autorelease, set/unset the tail call
keyword as appropriate.

*NOTE* I also handled the case where objc_autorelease is converted in
OptimizeReturns to an autoreleaseRV which still violates the ARC semantics. I
will be removing that in a later patch and I wanted to make sure that the tree
is in a consistent state vis-a-vis ARC always.

Additionally some test cases are provided and all tests that have tail call marked
objc_autorelease keywords have been modified so that tail call has been removed.

*NOTE* One test fails due to a separate bug that I am going to commit soon. Thus
I marked the check line TMP: instead of CHECK: so make check does not fail.

(PR14910). Until we have a good way to deal with this, we just won't
