Chris Lattner de023a3c1d building on the new CallGraphSCC abstraction, teach CallGraphSCCPassManager 
to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

on it.

Dan Gohman 91f8ad7bd3 Add an autoconf check for -retain-symbols-file and conditionalize 
use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

Chris Lattner 4422d31b84 introduce a new CallGraphSCC class, and pass it around 
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,
but now we have a much tidier interface.

Johnny Chen b90b6f1a35 Fixed a bug in DisassembleN1RegModImmFrm() where a break stmt was missing for a 
case.  Also, the 0xFF hex literal involved in the shift for ESize64 should be
suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().

llvm-svn: 101550
 2010-04-16 22:17:36 +00:00
Douglas Gregor b33eed0ced Collapse the three separate initialization paths in 
TryStaticImplicitCast (for references, class types, and everything
else, respectively) into a single invocation of
InitializationSequence.

One of the paths (for class types) was the only client of
Sema::TryInitializationByConstructor, which I have eliminated. This
also simplified the interface for much of the cast-checking logic,
eliminating yet more code.

I've kept the representation of C++ functional casts with <> 1
arguments the same, despite the fact that I hate it. That fix will
come soon. To satisfy my paranoia, I've bootstrapped + tested Clang
with these changes.

Ted Kremenek 7afa85b8fa Rework USR generation for symbols with no linkage. Many of the USRs are now shortened, 
and we now include the file name that declares the symbol with no linkage in the USR.
USRs for such symbols are generated only in restructed cases, e.g., anonymous enum declarations,
typedefs, etc.

Chris Lattner 3cff64ab58 fix a bogus assertion exposed by a recent change: packing the 
struct may cause it to shrink more than one byte.  Before
my recent changes we compiled the new test into:

%0 = type { [6 x i8] }
@x = global %0 { [6 x i8] undef }, align 2        ; <%0*> [#uses=0]

which is obviously bogus.  Now we compile it into:

%0 = type <{ i32, i8, i8 }>
@x = global %0 zeroinitializer, align 2           ; <%0*> [#uses=0]

Where the last byte only is tail padding.

Johnny Chen 807e1748fc Multiclass LdStCop was using pre-UAL syntax LDC<c>L for the L fragment. Changed 
to the UAL syntax of LDCL<c>, instead.

Add a test case for this change which also tests the removal of assert() from
printAddrMode2OffsetOperand().

Douglas Gregor 5c8ffab9fb Switch the checking of implicit casts for static_cast, C-style, and 
functional casts over to InitializationSequence, eliminating a caller
of Sema::TryImplicitConversion. We also get access and ambiguity
checking "for free".

More cleanups to come in this routine.
