Single and FP double reg types (which share the same reg class).
Now all methods marking/finding unused regs consider the regType
within the reg class, and SparcFloatRegClass specializes this code.
(2) Remove machine-specific regalloc. methods that are no longer needed.
In particular, arguments and return value from a call do not need
machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
overloading when an include file is omitted.

causing a nasty array bound error later.
2. Fix silly typo causing logical shift of unsigned long to use
SRL instead of SRLX.

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.)

of codes. For example,
short kernel (short t1) {
t1 >>= 8; t1 <<= 8;
return t1;
}
became:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1]
%tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1]
%tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1]
ret short %tmp.8
}
before, now it becomes:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1]
ret short %tmp.8
}
which will become:
short %kernel(short %t1.1) {
%tmp.3 = and short %t1.1, 0xFF00
ret short %tmp.3
}
This implements cast-set.ll:test4 and test5

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.

This fixes a long time annoyance which caused prototypes for bzero, bcopy,
bcmp, fputs, and fputs_unlocked to never get deleted. Grr.

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.

IC: (X ^ C1) | C2 --> (X | C2) ^ (C1&~C2)
We are now guaranteed that all 'or's will be inside of 'and's, and all 'and's
will be inside of 'xor's, if the second operands are constants.
