defined in function constant pools. The assembler grammar has long
disallowed functions from having constant pools, so all of this stuff is
dead.
This makes it an immediate error for functions to refer to nonexisting
types, fixing Regression/Verifier/2005-03-21-UndefinedTypeReference.ll.
Before, references to non-existing types in functions would only be
detected when the subsequent function was parsed, due to the call to
"ResolveTypes". "ResolveTypes" has not resolved any types for a long time,
instead it emitted an error message if no resolved types are left. Since
the only caller of this method is in the module code, just inline it.

Make sure to check isValueValidForType on floating point constants and give \
an error if the value is not valid, otherwise it would assert in the VMCore

Correct the dependency of the Lexer.o file on the constructed
llvmAsmParser.h header file. It is not the Lexer.cpp file that depends on
the header, its the output of compiling Lexer.cpp, Lexer.o

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

* Simplify a lot of code because type's cannot be in function symbol tables
* Fix memory leaks in handling of redefined function prototypes
* Don't use SymbolTable directly for stuff that we can go through the Module
for.
* Fix some minor bugs on obscure testcases like:
test/Feature/globalredefinition.ll
* Do not create GlobalVariable objects for forward referenced Functions!
* When forward referencing a function in a constant expression, do not create
a placeholder, add a bunch of references to it, then turn around and
replaceAllUsesOfWith on it with a new global, deleting the placeholder.
Instead, when we find the real definition of the global, just use the
placeholder instead of creating a new object.
This substantially simplifies the asmwriter and should even speed it up on
cases heavy in constantexprs (like C++, Java, MSIL)...
llvm-svn: 14830
replaceAllUsesWith'ing any forward references, just use the forward
reference if it exists.
This introduces GetForwardRefForGlobal, which will eventually completely
replace the horrible DeclareNewGlobalValue function.
llvm-svn: 14828
to substantially simplify the result. In particular, we no longer create
GlobalVariables and then immediately destroy them when they are duplciate
definitions.
The real point of this patch though is that it gets us closer to the
DeclareNewGlobalValue calls...
