their names more decriptive. A name consists of the base name, a
default operand size followed by a character per operand with an
optional special size. For example:
ADD8rr -> add, 8-bit register, 8-bit register
IMUL16rmi -> imul, 16-bit register, 16-bit memory, 16-bit immediate
IMUL16rmi8 -> imul, 16-bit register, 16-bit memory, 8-bit immediate
MOVSX32rm16 -> movsx, 32-bit register, 16-bit memory
llvm-svn: 11995
the size of the immediate and the memory operand on instructions that
use them. This resolves problems with instructions that take both a
memory and an immediate operand but their sizes differ (i.e. ADDmi32b).

MRegisterInfo::getNumRegs() instead of
MRegisterInfo::FirstVirtualRegister.
Also use MRegisterInfo::is{Physical,Virtual}Register where
appropriate.

ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
b) add isUse(), isDef()
c) rename opHiBits32() to isHiBits32(),
opLoBits32() to isLoBits32(),
opHiBits64() to isHiBits64(),
opLoBits64() to isLoBits64().
This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

strings with the stuff that used to print to an ostream directly. We now NEVER build
up big strings, only to print them once they are formed.

into the struct case.
* Extend printConstantValueOnly to print .zero's if the initializer is zero
* Delete dead isConstantFunctionPointerRef function
* Emit the appropriate assembly for the various linkage types!
llvm-svn: 8417
Fixes test case test/Programs/LLVMSource/2003-08-03-ReservedWordGlobal.ll.
Also: Refactor implicit-uses printing into its own method.
Remove a couple of unused variables.
llvm-svn: 7737
* Use .zero to emit padding between struct elements
* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.

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().
llvm-svn: 7275
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.
