Chris Lattner 047fd2fd97 major cleanups, much of this file was incorrectly indented. 
llvm-svn: 92262
 2009-12-29 09:22:47 +00:00
Chris Lattner 573f294c00 one pass of cleanup over DebugInfo.h. Much more is still needed.

Chris Lattner a0566979b7 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

Chris Lattner 5d3b077111 sink twine.h down out of Value.h. It is annoying that you need 
to #include Twine.h just to give a twine a default value.

Chris Lattner 241264ee32 When doing v1->RAUW(v2), don't do anything to metadata. We don't know 
why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

Chris Lattner d8eb2cf571 sink the Instruction::HasMetadata bit into SubclassData. 
llvm-svn: 92240
 2009-12-29 02:46:09 +00:00
Chris Lattner b9c8651b8c add a layer of accessors around the Value::SubClassData member, and use 
a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

Chris Lattner 2f2aa2b067 This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

Chris Lattner 17079fc0fa split code that doesn't need to be templated out of IRBuilder into a new 
non-templated IRBuilderBase class.  Move that large CreateGlobalString

Chris Lattner 588096e51d Rewrite the function-local validation logic for MDNodes (most of r91708). 
Among other benefits, this doesn't leak the SmallPtrSet, has the verifier
code in the verifier pass, actually does the verification at the end,
and is considerably simpler.

Chris Lattner 74a6ad6f29 move ElementVH out of the MDNode class into the MDNode.cpp file. Among 
other things, this avoids vtable and rtti data for it being splatted in 
every translation unit that uses it.

Douglas Gregor 4ee2cf658c Move the two definitions of operator<< into namespace llvm, so they

performance back down to acceptable-for-diagnostics levels, even for
long doubles.

Chris Lattner f5e3ed64d5 handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a

Douglas Gregor 93254e1ffb Move the extern symbol declarations outside of 
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

David Greene 64506db8e8 Provide dbgs(), a circular-buffering debug output stream. By default it 
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.

David Greene 7ffbb50edf Add circular_raw_ostream, which buffers its output in a circular queue 
and outputs it when explicitly flushed.  The intent is to use it in
situations such as debug output logging where a signal handler can take
care of flushing the buffer at program termination.
