6 years ago[CFG] Add extra context to C++ constructor statement elements.
Artem Dergachev [Thu, 8 Feb 2018 22:58:15 +0000 (22:58 +0000)]
[CFG] Add extra context to C++ constructor statement elements.

This patch adds a new CFGStmt sub-class, CFGConstructor, which replaces
the regular CFGStmt with CXXConstructExpr in it whenever the CFG has additional
information to provide regarding what sort of object is being constructed.

It is useful for figuring out what memory is initialized in client of the
CFG such as the Static Analyzer, which do not operate by recursive AST
traversal, but instead rely on the CFG to provide all the information when they
need it. Otherwise, the statement that triggers the construction and defines
what memory is being initialized would normally occur after the
construct-expression, and the client would need to peek to the next CFG element
or use statement parent map to understand the necessary facts about
the construct-expression.

As a proof of concept, CFGConstructors are added for new-expressions
and the respective test cases are provided to demonstrate how it works.

For now, the only additional data contained in the CFGConstructor element is
the "trigger statement", such as new-expression, which is the parent of the
constructor. It will be significantly expanded in later commits. The additional
data is organized as an auxiliary structure - the "construction context",
which is allocated separately from the CFGElement.

Daniel Neilson [Thu, 8 Feb 2018 17:33:08 +0000 (17:33 +0000)]
[LoopIdiom] Be more aggressive when setting alignment in memcpy

Summary:
This change is part of step five in the series of changes to remove alignment argument from
memcpy/memmove/memset in favour of alignment attributes. In particular, this changes the
LoopIdiom pass to cease using the old IRBuilder CreateMemCpy single-alignment APIs in
favour of the new API that allows setting source and destination alignments independently.
This allows us to be slightly more aggressive in setting the alignment of memcpy calls that
loop idiom creates.

Steps:
Step 1) Remove alignment parameter and create alignment parameter attributes for
memcpy/memmove/memset. ( rL322965, rC322964, rL322963 )
Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing
source and dest alignments. ( rL323597 )
Step 3) Update Clang to use the new IRBuilder API. ( rC323617 )
Step 4) Update Polly to use the new IRBuilder API. ( rL323618 )
Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API,
and those that use use MemIntrinsicInst::[get|set]Alignment() to use [get|set]DestAlignment()
and [get|set]SourceAlignment() instead. ( rL323886, rL323891, rL324148, rL324273, rL324278,
rL324384, rL324395, rL324402 )
Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the
MemIntrinsicInst::[get|set]Alignment() methods.

[clang-format] Do not break Objective-C string literals inside array literals

Summary:
Concatenating Objective-C string literals inside an array literal
raises the warning -Wobjc-string-concatenation (which is enabled by default).

clang-format currently splits and concatenates string literals like
the following:

  NSArray *myArray = @[ @"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" ];

into:

  NSArray *myArray =
        @[ @"aaaaaaaaaaaaaaaaaaaaaaaaaaaa"
           @"aaaaaaaaa" ];

which raises the warning. This is https://bugs.llvm.org/show_bug.cgi?id=36153 .

The options I can think of to fix this are:

1) Have clang-format disable Wobjc-string-concatenation by emitting
pragmas around the formatted code
2) Have clang-format wrap the string literals in a macro (which
disables the warning)
3) Disable string splitting for Objective-C string literals inside
array literals

I think 1) has no precedent, and I couldn't find a good
identity() macro for 2). So, this diff implements 3).

[clang-format] Do not break before long string literals in protos

Summary:
This patch is a follow-up to r323319 (which disables string literal breaking for
text protos) and it disables breaking before long string literals.

For example this:
```
keyyyyy: "long string literal"
```
used to get broken into:
```
keyyyyy:
    "long string literal"
```

While at it, I also enabled it for LK_Proto and fixed a bug in the mustBreak code.

6 years agoRewrite the flaky test_restart_bug test in a more deterministic way
Pavel Labath [Thu, 8 Feb 2018 10:37:23 +0000 (10:37 +0000)]
Rewrite the flaky test_restart_bug test in a more deterministic way

Summary:
The test was trying to reproduce a bug in handling of two concurrent
events, which was impossible to do reliably in a black-box style test.
In practice, this meant the test was only ever failing on remote
targets, as these were slow enough to trigger this.

Fortunately, we now have the ability to mock the server side of the
connection, which means we can simulate the failure deterministically,
so I rewrite the test to use the new gdb-client framework.

I've needed to add a couple of new packets to the mock server to be able
to do this. Instead of trying to guess how a "typical" gdb-client test
will want to handle this, I throw an exception in the implementation to
force the user to override them (the packets are only sent if the test
explicitly performs some action which will trigger them, so a basic test
which e.g. does not need the "continue" functionality will not need to
implement them).

[X86] Don't emit KTEST instructions unless only the Z flag is being used

Summary:
KTEST has weird flag behavior. The Z flag is set for all bits in the AND of the k-registers being 0, and the C flag is set for all bits being 1. All other flags are cleared.

We currently emit this instruction in EmitTEST and don't check the condition code. This can lead to strange things like using the S flag after a KTEST for a signed compare.

The domain reassignment pass can also transform TEST instructions into KTEST and is not protected against the flag usage either. For now I've disabled this part of the domain reassignment pass. I tried to comment out the checks in the mir test so that we could recover them later, but I couldn't figure out how to get that to work.

This patch moves the KTEST handling into LowerSETCC and now creates a ktest+x86setcc. I've chosen this approach because I'd like to add support for the C flag for all ones in a followup patch. To do that requires that I can rewrite the condition code going in the x86setcc to be different than the original SETCC condition code.

This fixes PR36182. I'll file a PR to fix domain reassignment once this goes in. Should this be merged to 6.0?
