055acae18c Start using the AsmPrinter to emit our first class constants. This also
drops our half-assed support for cygwin, which noone uses and doesn't work
anyway.

28531c71cd Fix PR422.
Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.

1cffdf0798 Fix frame pointer handling:
Reserve R0 in store/load from stack slot for building >32k offsets from SP
or FP.  This also requires we use R11 rather than R0 for holding the LR
value we want to save or restore.  Also, tell the register allocator not
to use R31 (our FP) in functions that have a frame pointer.  These changes
fix Burg.

1e13fd23d3 Allow any cl::opt to use the method getPosition() to retrieve the option's
absolute position on the command line. Similarly allow any cl::list to
use the method getPosition(n) to retrieve the absolute position of the nth
option in the list. This provides support for two things: (a) options like
-l that are actually positional and their order of occurrence matters when
they are intermixed with positional arguments like "a.o"; and (b) options
like -x LANG which affect only the positional arguments that come after
the option. In both cases, knowing the absolute position of a given option
helps.

block (common in a switch), make sure to remove extra edges in successor

would require pulling in the LoopExtract.cpp changes).

Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access

Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp

5a837defff FindGlobalNamed used to take 2.92s out of 8.39s running a profile build of
gccld -disable-opt on 252.eon.

This patch deletes it and replaces it with a map.  The proper fix for this
is to fix PR411, but this will do in the short term.

gccld on eon now takes 5.51s, which is 50% faster than before this patch. :)

These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.

71698285e8 This change fixed a bug in the function visitMul. The prior version
assumed that a constant on the RHS of a multiplication was either an
IntConstant or an FPConstant.  It checked for an IntConstant and then,
if it did not find one, did a hard cast to an FPConstant.  That code
would crash if the RHS were a ConstantExpr that was neither an
IntConstant nor an FPConstant.  This version replaces the hard cast
with a dyn_cast.  It performs the same way for IntConstants and
FPConstants but does nothing, instead of crashing, for constant
expressions.

The regression test for this change is 2004-07-27-ConstantExprMul.ll.

1b4aeb5cec As it happens, none of these TargetInstrInfo methods which are only
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

a9d790c831 Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the

%X = global float <some nan value>
