Change all machine basic block modifier functions in MRegisterInfo to
...
return the number of instructions added to/removed from the basic block
passed as their first argument.
Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Emit x86 instructions for: A = B op C, where A and B are 16-bit registers,
...
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.
This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version. Because these instructions are very common, this
can save a LOT of code space. For example, I sampled two benchmarks, 176.gcc
and 254.gap.
BM Old New Reduction
176.gcc 2673621 2548962 4.89%
254.gap 498261 475104 4.87%
Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc. Not bad.
Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.

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.

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.

lib/Target/X86/InstSelectSimple.cpp: Start counting arguments with 2,

because arguments start two stack slots off of EBP. Break out of the
for loop once the argument is found. Increment the counter at the end
of the loop instead of the beginning. Use addRegOffset and compute
the scale * index part at compile time instead of using the fancy
load instruction. Just because an instruction set has wacky addressing
modes doesn't mean we ought to use them (at least, if you believe Dave
Patterson).

(lib/Target/X86) InstSelectSimple.cpp:
Include llvm/DerivedTypes.h and iostream.
Refactor visitMul out into a wrapper around doMultiply(), so that we
can do multiplications on temporary values when we are doing
getelementptrs.
Refactor part of getReg out into makeAnotherReg, so that we can create
registers willy-nilly to hold temporary values, when we are doing
getelementptrs.
Add stub implementations of visitMallocInst and visitAllocaInst.
Add initial implementation of visitGetElementPtrInst.
In copyConstantToRegister:
We throw a *lot* of our asserts here. So, when we want to throw an
assert, print out to stderr whatever expr or whatever constant made
us barf.
Support copying ConstantPointerNull to register, using a move immediate
of zero.
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
from subregs of EAX. Add a FIXME note about how we would do it for
float-class return values.
Add a FIXME note about how we would cast float to int and back.
X86InstrInfo.def:
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.
(tools/jello) GlobalVars.cpp:
Include iostream.
If we have to emit a floating-point constant to memory, gamble and use
the same method as for ints.
If we have to emit a ConstantPointerNull to memory, try using a "void *"
and "NULL".
Otherwise, if we are going to throw an assert, print out whatever constant
made us barf, first.
