Switch lowering: enable whole-switch jump tables at -O0.

To same compile time, the analysis to find dense case-clusters in switches is
not done at -O0. However, when the whole switch is dense enough, it is easy to

MIR Serialization: initialize the fields without the default initializers in yaml::MachineFunction

My commit r239790 which introduced serialization for simple machine function attributes didn't
initialize them when parsing because I have misread the documentation for YAML IO's mapOptional
method. The mapOptional method doesn't actually set the values to the values returned by the
default constructor for that type when the key value pair is missing, it just doesn't modify
those values, so they still contain the value that was set during initialization by the default
constructor. But the fields in yaml::MachineFunction with types like unsigned and bool are not
initialized by default, and thus they can still be uninitialized after mapOptional during parsing.
This commit adds default initialization for those fields to prevent this.

intrinsics -- these do call (or invoke) LLVM level functions.

This change fixes this inconsistency by adding a call to the external

with the fact that these intrinsics also escape the function pointer

Devirtualize and pack MCFragment to reduce memory usage.

MCFragment didn't really need vtables.  The majority of virtual methods were just getters and setters.

This removes the vtables and uses dispatch on the kind to do things like delete which needs to

[X86] Cache variables that only depend on the subtarget

There is a one-to-one relationship between X86Subtarget and
X86FrameLowering, but every frame lowering method would previously pull
the subtarget off the MachineFunction and query some subtarget

Over time, these locals began to grow in complexity and it became
important to keep their names and meaning in sync across all of the

duplication by computing them once in the constructor.

[mips] [IAS] Fix LW with relative label operands.

Summary:
Previously, MCSymbolRefExpr::create() was called with a StringRef of the symbol
name, which it would then search for in the Symbols StringMap (from MCContext).

However, relative labels (which are temporary symbols) are apparently not stored
in the Symbols StringMap, so we end up creating a new {$,.L}tmp symbol
({$,.L}tmp00, {$,.L}tmp10 etc.) each time we create an MCSymbolRefExpr by
passing in the symbol name as a StringRef.

Fortunately, there is a version of MCSymbolRefExpr::create() which takes an
MCSymbol* and we already have an MCSymbol* at that point, so we can just pass
that in instead of the StringRef.

I also removed the local StringRef calls to MCSymbolRefExpr::create() from
expandMemInst(), as those cases can be handled by evaluateRelocExpr() anyway.

Chandler Carruth [Wed, 17 Jun 2015 07:12:40 +0000 (07:12 +0000)]
[PM/AA] Split the location computation out of getArgLocation so the
virtual interface on AliasAnalysis only deals with ModRef information.

This interface was both computing memory locations by using TLI and
other tricks to estimate the size of memory referenced by an operand,
and computing ModRef information through similar investigations. This
change narrows the scope of the virtual interface on AliasAnalysis
slightly.

Note that all of this code could live in BasicAA, and be done with
a single investigation of the argument, if it weren't for the fact that
the generic code in AliasAnalysis::getModRefBehavior for a callsite
calls into the virtual aspect of (now) getArgModRefInfo. But this
patch's arrangement seems a not terrible way to go for now.

The other interesting wrinkle is how we could reasonably extend LLVM
with support for custom memory location sizes and mod/ref behavior for
library routines. After discussions with Hal on the review, the
conclusion is that this would be best done by fleshing out the much
desired support for extensions to TLI, and support these types of
queries in that interface where we would likely be doing other library
API recognition and analysis.

Fix alignment issues in LLVM.

Adds static_asserts to ensure alignment of concatenated objects is
correct, and fixes them where they are not.

Also changes the definition of AlignOf to use constexpr, except on
MSVC, to avoid enum comparison warnings from GCC.

(There's not too much of this in llvm itself, most of the fun is in

Rename and improve emitSectionOffset.

Different object formats represent references from dwarf in different ways.

ELF uses a relocation to the referenced point (except for .dwo) and
COFF/MachO use the offset of the referenced point inside its section.

* It doesn't produce an offset on ELF.
* It changes behavior depending on how DWARF is represented, so adding
dwarf to its name is probably a good thing.

Improve handling of end of file in the bitcode reader.

Before this patch the bitcode reader would read a module from a file
that contained in order:

* Any number of non MODULE_BLOCK sub blocks.
* One MODULE_BLOCK
* Any number of non MODULE_BLOCK sub blocks.
* 4 '\n' characters to handle OS X's ranlib.

Since we support lazy reading of modules, any information that is relevant
for the module has to be in the MODULE_BLOCK or before it. We don't gain
anything from checking what is after.

This patch then changes the reader to stop once the MODULE_BLOCK has been
successfully parsed.

This avoids the ugly special case for .bc files in an archive and makes it
easier to embed bitcode files.

Fix PR 23525 - Separate header mass propagation in irregular loops.

Summary:
When propagating mass through irregular loops, the mass flowing through
each loop header may not be equal. This was causing wrong frequencies
to be computed for irregular loop headers.

Fixed by keeping track of masses flowing through each of the headers in
an irregular loop. To do this, we now keep track of per-header backedge
weights. After the loop mass is distributed through the loop, the
backedge weights are used to re-distribute the loop mass to the loop
headers.

Since each backedge will have a mass proportional to the different
branch weights, the loop headers will end up with a more approximate
weight distribution (as opposed to the current distribution that assumes
that every loop header is the same).
