fixes crashes where the insertion point was in a macro.  Instead of crashing, we want
to emit a warning.

Add a RewriteTest::ReplaceStmt method to factor the 'checking for
rewrite failed + emitting diagnostic if so' code.

Moved ValueKey/ValueMap declaration to ValueState.h.

llvm-svn: 46618

exposed a bug in APFloat's long double->double conversion of
NaNs.  Broke several things in the ieee part of gcc testsuite.

Add an extra operand to LABEL nodes which distinguishes between debug, EH, or misc labels. This fixes the EH breakage. However I am not convinced this is *the* solution.

Allow ComplexExpressions in InstrInfo.td files to be slightly more... complex! ComplexExpressions can now have attributes which affect how TableGen interprets
the pattern when generating matchin code. 

The first (and currently, only) attribute causes the immediate parent node of the ComplexPattern operand to be passed into the matching code rather than the node at the root of the entire DAG containing the pattern.

MRegisterInfo::getLocation() is a really bad idea. Its function is to calculate the offset from frame pointer to a stack slot and then storing the delta in a MachineLocation object. The name is bad (it implies a getter), and MRegisterInfo doesn't need to know about MachineLocation.
Replace getLocation() with getFrameIndexOffset() which returns the delta from frame pointer to stack slot. Dwarf writer can then use the information for whatever it wants.

(local) aliasing support.

Modified ExplodedGraph pretty-printer (for GRConstants) to also print out the
pointer value of the state associated with a node.  This way one can easily
see that two states are identical.

Add support for CallExpr::isBuiltinConstantExpr(). For now, this hook is used to support CFConstantStrings. Can be extended to support other built-in functions.

This allows the following code to compile without error...

#include <CoreFoundation/CoreFoundation.h>

#define CONST_STRING_DECL(S, V) const CFStringRef S = (const CFStringRef)__builtin___CFStringMakeConstantString(V);

CONST_STRING_DECL(kCFTimeZoneSystemTimeZoneDidChangeNotification, "kCFTimeZoneSystemTimeZoneDidChangeNotification")

in the backend. Introduce a new SDNode type, MemOperandSDNode, for
holding a MemOperand in the SelectionDAG IR, and add a MemOperand
list to MachineInstr, and code to manage them. Remove the offset
field from SrcValueSDNode; uses of SrcValueSDNode that were using
it are all all using MemOperandSDNode now.

Also, begin updating some getLoad and getStore calls to use the
PseudoSourceValue objects.

Most of this was written by Florian Brander, some
reorganization and updating to TOT by me.

Improved pretty-printing of LValues.
Parameters whose values are pointers/references are now assigned SymbolicLValues.

Hack Sema::MergeTypeDefDecl() to silently ignore duplicate typedef's in system headers files.

A bizarre, non-standard hook that many compilers appear to implement (sigh:-).

pretty-print a block's terminator.

When building CFGs, for IfStmts ('if'), we no longer add the ParenExpr
that is the subexpression of the IfStmt to the CFG; instead we add its
first descendant subexpression that is not a ParenExpr.
