Manman Ren 051d0b620d ObjC kindof: order the methods in global pool relative to availability.
r265877 tries to put methods that are deprecated or unavailable to the
front of the global pool to emit diagnostics, but it breaks some of
our existing codes that depend on choosing a certain method for id
lookup.

This commit orders the methods with the same declaration with respect
to the availability, but do not order methods with different declaration.

Reid Kleckner 9305fd1f86 [CodeGen] Avoid ctor/dtor boilerplate with some C++11
Non-owning pointers that cache LLVM types and constants can use
'nullptr' default member initializers so that we don't need to mention
them in the constructor initializer list.

Owning pointers should use std::unique_ptr so that we don't need to
manually delete them in the destructor. They also don't need to be
mentioned in the constructor at that point.

Tim Northover 5c02f9ad28 ARM: override cost function to re-enable ConstantHoisting (& fix it).
At some point, ARM stopped getting any benefit from ConstantHoisting because
the pass called a different variant of getIntImmCost. Reimplementing the
correct variant revealed some problems, however:

  + ConstantHoisting was modifying switch statements. This is simply invalid,
    the cases must remain integer constants no matter the notional cost.
  + ConstantHoisting was mangling alloca instructions in the entry block. These
    should be handled by FrameLowering, so constants actually have a cost of 0.
    Worse, the resulting bitcasts meant they became dynamic allocas.

Duncan P. N. Exon Smith 11f60fd65a ValueMapper: Resolve cycles on the new nodes
Fix a major bug from r265456.  Although it's now much rarer, ValueMapper
sometimes has to duplicate cycles.  The
might-transitively-reference-a-temporary counts don't decrement on their
own when there are cycles, and you need to call MDNode::resolveCycles to
fix it.

r265456 was checking the input nodes to see if they were unresolved.
This is useless; they should never be unresolved.  Instead we should
check the output nodes and resolve cycles on them.

Matthias Braun 707e02c273 ARM: Use a callee save register for the swiftself parameter.
It is very likely that the swiftself parameter is alive throughout most
functions function so putting it into a callee save register should
avoid spills for the callers with only a minimum amount of extra spills
in the callees.

Currently the generated code is correct but unnecessarily spills and
reloads arguments passed in callee save registers, I will address this
in upcoming patches.

This also adds a missing check that for tail calls the preserved value
of the caller must be the same as the callees parameter.

Kevin Enderby 8702574557 Start to add real error messages for malformed Mach-O files.
And update the existing test cases in test/Object/macho-invalid.test
to use llvm-objdump with the -macho option to produce these
error messages and stop producing the generic "Invalid data
was encountered while parsing the file" message.

Working from the beginning of the file, if the mach header is too large for
the size of the file and then if the load commands that follow extend past
the end of the file these two errors now generate correct error messages.

Both of these have existing test cases in test/Object/macho-invalid.test .

But the first with macho-invalid-header it will never trigger the error message
"mach header extends past the end of the file" using any of the llvm tools as
they all use identify_magic() which rejects files with the correct magic number
that are too small in size.  So I tested this by hacking that code and seeing the
error message down in parseHeader() really does happen.  So in case there
is ever code in llvm that directly calls createMachOObjectFile() this error
message will be correctly produced.

The second error message of "load commands extends past the end of the file"
is triggered by a number of existing tests cases in test/Object/macho-invalid.test .
Also other tests trigger different error messages now like "ilocalsym plus
nlocalsym in LC_DYSYMTAB load command extends past the end of the
symbol table".

There are two existing test cases that still get the "Invalid data was encountered ..."
error messages that I will tackle next.  But they will involve a bit of pluming an
Expect<...> up through the call stack and I want to do those as separate changes.

FYI, for those test cases that were trying to test specific errors that now get
different errors I’ll fix those in follow on changes and create new test cases
for those so they test the error they were meant to test.

Bruno Cardoso Lopes c54768f7fa [SemaObjC] Properly handle mix between type arguments and protocols.
Under certain conditions clang currently fails to properly diagnostic ObjectC
parameter list when type args and protocols are mixed in the same list. This
happens when the first item in the parameter list is a (1) protocol, (2)
unknown type or (3) a list of protocols/unknown types up to the first type
argument. Fix the problem to report the proper error, example:

NSArray<M, NSValue *, NSURL, NSArray <id <M>>> *foo = @[@"a"];
NSNumber *bar = foo[0];
NSLog(@"%@", bar);

$ clang ...
x.m:7:13: error: angle brackets contain both a type ('NSValue') and a protocol ('M')
        NSArray<M, NSValue *, NSURL, NSArray <id <M>>> *foo = @[@"a"];

Davide Italiano 236e7444dd [DebugInfo] Optimize memory layout of DISubprogram.
A DISubprogram on x86_64 was 48 bytes. During an LTO build we
end up allocating *a lot* of these (see Duncan's numbers on
llvm-dev and/or my numbers in the review link).
This change reduces the size to 40 bytes, with a nice effect
on peak memory usage when LTO'ing clang.
There are more classes in the hierarchy which can be compacted
so more patches will come. DISubprogram was the biggest offender
in my profiling, anyway.

This patch implements the --dynamic-list option, which adds a list of
global symbol that either should not be bounded by default definition
when creating shared libraries, or add in dynamic symbol table in the

The patch modifies the ScriptParserBase class to use a list of Token
instead of StringRef, which contains information if the token is a
quoted or unquoted strings. It is used to use a faster search for
exact match symbol name.

The input file follow a similar format of linker script with some
simplifications (it does not have scope or node names). It leads
to a simplified parser define in DynamicList.{cpp,h}.

Different from ld/gold neither glob pattern nor mangled names
(extern 'C++') are currently supported.
