Chris Lattner e9340228c9 Fix bug: FunctionResolve/2003-07-23-CPR-Reference.ll 
This fixes a long time annoyance which caused prototypes for bzero, bcopy,
bcmp, fputs, and fputs_unlocked to never get deleted.  Grr.

Brian Gaeke a92dce471b Printer.cpp: Ditch addRequired/getAnalysis, because they leave 
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().

Brian Gaeke c3998cb090 Add, rewrite, and/or reformat many comments. 
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.

Chris Lattner 8f0d15601a IC: (X & C1) | C2 --> (X | C2) & (C1|C2) 
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.

John Criswell b65ddad4f4 Repaired the --enable and --disable options. 
llvm-svn: 7239
 2003-07-22 21:00:24 +00:00
John Criswell 5ec24d8733 Fixed the enable/disable options. The AC_ARG_ENABLE macro does not perform 
the *action-if-not-given* code when the --disable option is used.
Rather, the AC_ARG_ENABLE macro sets the $enableval variable, which then needs
to be checked to determine if --enable, --disable, or neither was specified.
