Mangler.cpp: Constify parameter to makeNameProper, and use const_iterator.
Make Count an unsigned int, and use utostr().
Don't name parameters things that start with underscore.
Mangler.h: All of the above, and also: Add Emacs mode-line. Include <set>.

SlotCalculator in CWriter. (Unfortunately, all this means a lot of
X86/Printer's methods have to be de-constified again. Oh well.)

doFinalization too except that would have made them shadow, not override,
the parent class :-P.
Allow *any* constant cast expression between pointers and longs,
or vice-versa, or any widening (not just same-size) conversion that
isLosslesslyConvertibleTo approves. This fixes oopack.

Printer::doFinalization() out in the cold. Now we pass in a TargetMachine
to Printer's constructor and get the TargetData from the TargetMachine.
Don't pass TargetMachine or MRegisterInfo objects around in the Printer.
Constify TargetData references.
X86.h: Update comment and prototype of createX86CodePrinterPass().
X86TargetMachine.cpp: Update callers of createX86CodePrinterPass().

Stop passing ostreams around: we already have one perfectly good ostream
and we can all share it.
Stop stashing a pointer to TargetData in the Pass object, because that will
lead to a crash if there are no functions in the module (ouch!) Instead,
use addRequired() and getAnalysis(), like we always should have done.
Move the check for ConstantExpr up before the check for isPrimitiveType,
because we need to be able to catch e.g. ubyte (cast bool false to ubyte),
whose type is primitive but which is nevertheless a ConstantExpr, by calling
our specialized handler instead of the AsmWriter. This would result in
assembler errors when we would try to output something like ".byte (cast
bool false to ubyte)".
GC some unused variable declarations.

Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic
call which causes llc & lli to core-dump.
Add a sort-of treatment of cast double to ulong. I am not really sure
what a user should expect to see upon casting a negative FP value to
unsigned long long. But with what is given here, I was able to write
a program that could cast -123.456 to ulong and back and get -123.0,
which seems like a step in the right direction. GCC seems to give you
0. I don't know if I'd consider that useful.
These cases were coming up in GNU coreutils-5.0.

Printer.cpp: Print implicit uses for AddRegFrm instructions. Break gas
bug workarounds up into separate stanzas of code for each bug. Add new
workarounds for fild and fistp.
X86InstrInfo.def: Add O_ST0 implicit uses for more FP instrs where they
obviously apply. Also add PrintImplUses flags for FP instrs where they
are necessary for gas to understand the output.

SingleSource except oopack and Oscar. (Sorry, Oscar.)
include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add
accessors for ImplicitUses/Defs.
lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you
really wanted this, just use MI->print(O, TM); instead...
lib/Target/X86:
FloatingPoint.cpp: ...like this.
X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses
target-specific flag bit.
X86InstrInfo.def: Add the PrintImplUses flag to all the instructions
which implicitly use CL, because the assembler needs to see the CL in
order to generate the right instruction.
Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName
to name constants in the constant pool for each function instead. This
avoids keeping state between runOnMachineFunction() invocations, which
is a no-no. Having MangledGlobals be global is a bogon I'd like to get
rid of too, but making it a static member of Printer causes link errors
(why???).
Make NumberForBB into a member of Printer instead of a global, too.
Make printOp and printMemReference into methods of Printer.
X86InstrInfo::print is now Printer::printMachineInstruction, because
TargetInstrInfo::print is history. (Because of this, we have to qualify
the names of some TargetInstrInfo methods we call.)
Print out the ImplicitUses field of any instruction we print that has
the PrintImplUses bit set.

Remove support for running arbitrary optimization passes. Use opt instead.
Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted

Update file comment to contain a bunch of the overview mapping-info
documentation previously buried within the file.
Remove some unnecessary include/using stmts.
Rename pass to MappingInfoCollector.
Rewrite a lot of it so it doesn't use global instance variables and so
it outputs into MappingInfo objects and then dumps those out, instead of going
straight to an assembly file.
Change name of factory to getMappingInfoCollector.
Fold prologue & epilogue writers into MappingInfo methods.

Fix typo in header.
Add IsArchive static method.
Roll LoadLibraryFromDirectory() into LoadLibrary(), and factor
LoadLibraryExactName() out of the result. Instead of treating the current
directory specially, just insert it into LibPaths in the beginning of
main().
Make LoadLibrary() take a "search" flag that says whether to search for the
correct library, or just trust that LibName is right.
Make LinkLibrary() take a "search" flag, and pass it to LoadLibrary().
Change the for-loop over InputFilenames to detect ar archives and link them
in as libraries without searching.
Change the for-loop over Libraries to explicitly turn on the "search" flag
to LinkLibrary() that makes LoadLibrary() search for the correct library
(i.e., when processing -lNAME options.)

Refactor part of getReg out into makeAnotherReg, so that we can create

Add initial implementation of visitGetElementPtrInst.
In copyConstantToRegister:
We throw a *lot* of our asserts here. So, when we want to throw an

us barf.
Support copying ConstantPointerNull to register, using a move immediate

Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
of the numbers in the other instruction names. All uses modified.
Teach visitCallInst to extract byte- and short-class return values

float-class return values.
Add a FIXME note about how we would cast float to int and back.
