- Used to mark fake instructions which don't correspond to an actual machine
instruction (or are duplicates of a real instruction). This is to be used for
"special cases" in the .td files, which should be ignored by things like the
assembler and disassembler. We still need a good solution to handle pervasive
duplication, like with the Int_ instructions.
- Set the bit on fake "mov 0" style instructions, which allows turning an
assembler matcher warning into a hard error.

break later passes which expect the address mode to be well-formed.

Rebuild RegScavenger::DistanceMap each time it is needed.
...
The register scavenger maintains a DistanceMap that maps MI pointers to their
distance from the top of the current MBB. The DistanceMap is built
incrementally in forward() and in bulk in findFirstUse(). It is used by
scavengeRegister() to determine which candidate register has the longest
unused interval.
Unfortunately the DistanceMap contents can become outdated. The first time
scavengeRegister() is called, the DistanceMap is filled to cover the MBB. If
then instructions are inserted in the MBB (as they always are following
scavengeRegister()), the recorded distances are too short. This causes bad
behaviour in the included test case where a register use /after/ the current
position is ignored because findFirstUse() thinks is is /before/ the current
position. A "using an undefined register" assertion follows promptly.
The fix is to build a fresh DistanceMap at the top of scavengeRegister(), and
discard it after use. This means that DistanceMap is no longer needed as a
RegScavenger member variable, and forward() doesn't need to update it.
The fix then discloses issue number two in the same test case: The candidate
search in scavengeRegister() finds a CSR that has been saved in the prologue,
but is currently unused. It would be both inefficient and wrong to spill such
a register in the emergency spill slot. In the present case, the emergency
slot restore is placed immediately before the normal epilogue restore, leading
to a "Redefining a live register" assertion.
Fix number two: When scavengerRegister() stumbles upon an unused register that
is overwritten later in the MBB, return that register early. It is important
to verify that the register is defined later in the MBB, otherwise it might be
an unspilled CSR.

Make the big switch: Change MCSectionMachO to represent a section *semantically*
...
instead of syntactically as a string. This means that it keeps track of the
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and
"attribute(section)", so we should now start getting errors about invalid
section attributes from the compiler instead of the assembler on darwin.
Still todo:
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
S_GB_ZEROFILL segment type?

Modifications to dyn_cast/cast to make them work for objects too, instead of only pointers.
...
The use case is if you have a wrapper class:
class Base {
void *Ptr;
public:
Base() : Ptr(0) { }
operator bool() const { return Ptr; }
.....
}
and sub-wrappers that have exactly the same size:
class Sub : public Base {
public:
....
static bool classof(const Base*);
}
and in the code you would do:
void f(Base b) {
Sub sub = dyn_cast<Sub>(b);
if (sub) {
....
}
}

http://llvm.org/viewvc/llvm-project?view=rev&revision=78127 , I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.
This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of

to be one, rewriting getLoops as SCEVVisitor will reduce complexity to

llvm-mc/AsmMatcher: Move to a slightly more sane matching design.
...
- Still not very sane, but a least its not 60k lines on X86. :)
- In terms of correctness, currently some things are hard wired for X86, and we
still don't properly resolve ambiguities (this is ignoring the instructions
we don't even match due to funny .td stuff or other corner cases).
The high level changes:
1. Represent tokens which are significant for matching explicitly as separate
operands. This uniformly handles not only the instruction mnemonic, but
also 'signficiant' syntax like the '*' in "call * ...".
2. Separate the matching of operands to an instruction from the construction of
the MCInst. In theory this can be done during matching, but since the number
of variations is small I think it makes sense to decompose the problems.
3. Improved a few of the mechanisms to at least successfully flatten / tokenize
the assembly strings for PowerPC and ARM.
4. The comment at the top of AsmMatcherEmitter.cpp explains the approach I'm
moving towards for handling ambiguous instructions. The high-bit is to infer
a partial ordering of the operand classes (and force the user to specify one
if we can't) and use that to resolve ambiguities.

pure virtual method to assign sections to globals with a specified
section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is

Major calling convention code refactoring.
...
Instead of awkwardly encoding calling-convention information with ISD::CALL,
ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering
provides three virtual functions for targets to override:
LowerFormalArguments, LowerCall, and LowerRet, which replace the custom
lowering done on the special nodes. They provide the same information, but
in a more immediately usable format.
This also reworks much of the target-independent tail call logic. The
decision of whether or not to perform a tail call is now cleanly split
between target-independent portions, and the target dependent portion
in IsEligibleForTailCallOptimization.
This also synchronizes all in-tree targets, to help enable future
refactoring and feature work.

Don't flush the raw_ostream between each MachineFunction. These flush
...
calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.
