A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.

When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases.
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again.

Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.

Duncan P. N. Exon Smith [Thu, 26 Feb 2015 04:53:00 +0000 (04:53 +0000)]
FileCheck: Add CHECK-SAME

Add `CHECK-SAME`, which requires that the pattern matches on the *same*
line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline
is allowed in the skipped region.  This is similar to `CHECK-NEXT`,
which requires exactly 1 newline in the skipped region.

My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy.  This allows CHECK sequences like the
following:

    CHECK:      ![[REF]] = !SomeMDNode(
    CHECK-SAME: file: ![[FILE:[0-9]+]]
    CHECK-SAME: otherField: 93{{[,)]}}

which is equivalent to:

    CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}

While this example just has two fields, many nodes in debug info have
more than that.  `CHECK-SAME` will keep the logic easy to follow.

Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:

    CHECK:      ![[REF]] = !SomeMDNode(
    CHECK-SAME: file: ![[FILE:[0-9]+]]
    CHECK-NOT:  unexpectedField:
    CHECK-SAME: otherField: 93{{[,)]}}
    CHECK-NOT:  otherUnexpectedField:
    CHECK-SAME: )

which doesn't seem to have an equivalent `CHECK` line.

PlaceSafepoints: use IRBuilder helpers

Use the IRBuilder helpers for gc.statepoint and gc.result, instead of
coding the construction by hand. Note that the gc.statepoint IRBuilder
handles only CallInst, not InvokeInst; retain that part of hand-coding.

Add -fuse-line-directive flag to control usage of #line with -E

Currently -fms-extensions controls this behavior, which doesn't make
much sense. It means we can't identify what is and isn't a system header
when compiling our own preprocessed output, because #line doesn't
represent this information.

If someone is feeding Clang's preprocessed output to another compiler,
they can use this flag.

Fixes PR20553.

Remove a FIXME.

Explanation: This function is in TargetLowering because it uses
RegClassForVT which would need to be moved to TargetRegisterInfo
and would necessitate moving isTypeLegal over as well - a massive
change that would just require TargetLowering having a TargetRegisterInfo
class member that it would use.
