Chris Lattner 681f79124a allow clients of the asmprinter to opt-out of the boilerplate with a #define.

Douglas Gregor c9c02ed8f4 Keep track of when declarations are "used" according to C and 
C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

Dan Gohman c702fc0e64 Make GetMinTrailingZeros a member function of ScalarEvolution, 
so that it can access the TargetData member (when available) and
use ValueTracking.h information to compute information for
SCEVUnknown Values.

Also add GetMinLeadingZeros and GetMinSignBits functions,
with minimal implementations.

Dan Gohman cc31110b95 Re-apply r73718, now that the fix in r73787 is in, and add a 
hand-crafted testcase which demonstrates the bug that was exposed
in 254.gap.

Owen Anderson b07dd959a4 Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation 
gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.

llvm-svn: 73775
 2009-06-19 17:45:12 +00:00
Dan Gohman 2199dbc5ff Don't (unconditionally) use getSCEVAtScope to simplify the step 
expression in IVUsers, because in the case of a use of a non-linear
addrec outside of a loop, this causes the addrec to be evaluated as
a linear addrec.

Ted Kremenek c55f0cdaa0 Remove more GetSVal/GetLValue methods in GRExprEngine/GRState, instead 
preferring to use their replacements in GRState. This further unifies the code
paths for such logic and leads to some code reduction.

Chris Lattner d0a363e03b make jump threading handle lexically identical compare instructions 
as if they were multiple uses of the same instruction.  This interacts
well with the existing loadpre that j-t does to open up many new jump
threads earlier.

Duncan Sands e532b557c4 Since -Wno-long-long is ignored without -pedantic, 
place it with -pedantic.  Remove -Wunused since it
is implied by -Wall.  Group -Wno-unused-parameter
with -Wall -W since it is the combination of these
two that turns on -Wunused-parameter.

Zhongxing Xu 54fb536b5c A further step of r73690: associate the cast-to type with the created symbol, 
because the type of the symbol is used to create the default range. We need the
sign to be consistent.

Eli Friedman d984158320 Mark a few Thumb instructions commutable; just happened to spot this 
while experimenting.  I'm reasonably sure this is correct, but please 
tell me if these instructions have some strange property which makes this
change unsafe.

Chris Lattner 3235c38dbb Add some scaffolding for a new experimental asmprinter 
implementation.  The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst.  MCInst
and the new asmprinters will not depend on most of the 
llvm code generators.  This allows building diassemblers
that don't link in the whole llvm code generator.  This is
step #1 of many.

Chris Lattner 8284b66264 merge the common darwin settings from the X86/PPC/ARM targets 
into DarwinTargetAsmInfo.cpp.  The remaining differences should

doesn't, etc.
