Chris Lattner e5b80dfdf1 Until the pattern matching instruction selector is finished, enable debug output from it

2003-08-11 15:11:01 +00:00
Chris Lattner e61db425e8 Add support for a pattern matching instruction selector. This is still in
the early implementation phases, so it is disabled by default

Chris Lattner 7c257321c7 This is the real fix for the previous register allocator problem.
Physical registers should not float around.

Chris Lattner 148747e162 Add patterns for (mov R, R) (mov R, I) and subtracts. The moves are to enable
testing, the subtracts are because I was in the neighborhood.

Chris Lattner 5dcb654662 * Sort #includes, remove dupliates
* 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.

Brian Gaeke a2d9f40693 I think local symbols in X86 GAS have to start with .L, not just
.; so I have changed the basic block markers to start with .L.  I also
broke up a >80char line.

Brian Gaeke 46f8b71376 Use unified CWriter-X86/Printer name mangler. Do not bother using
SlotCalculator in CWriter.  (Unfortunately, all this means a lot of
X86/Printer's methods have to be de-constified again.  Oh well.)

Brian Gaeke 391f69b0ff Constify most methods. We could have constified doInitialization and
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.

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 6077c3195f Simplify code by using ConstantInt::getRawValue instead of checking to see

Brian Gaeke 26bb3c1df6 Please, save your applause^H^H^H^H^H^H^H^Hflames for the end...
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.
