Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.
This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
bits in an integer. The Type classes SubclassData field is used to
store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
64-bit integers. These are replaced with just IntegerType which is not
a primitive any more.
3. Adjust the rest of LLVM to account for this change.
Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types. Future increments
will rectify this situation.

recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

in getLocalSlot fires on many, many values. It broke nearly all of
the dejagnu tests. Simple changes to the assertion did not fix the
problem.

Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
function result, they are now located after the function header's
closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
there is no support for recognizing it in the lexer nor doing anything
with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
returning multiple attributes. This required a change in its interface.
I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.
llvm-svn: 32904
Remove all grammar conflicts from assembly parsing. This change involves:
1. Making the "type" keyword not a primitive type (removes several
reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
and global variables. In particular "appending" can no longer be
specified for a function. A differentiation was made between the various
internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
function. This disambiguates several cases where a named function return
type could get confused with the definition of a new type. Using the
keyword eliminates all shift/reduce conflicts and the remaining
reduce/reduce conflicts.
These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.

values regardless of the signedness of the constant's type, it is okay to
always make the AsmWriter.cpp print constant ints as signed values. The
AsmParser will automatically handle things like: uint -1 as a result.

it was effectively set to true by this:
- if ((PrintName || isa<GlobalValue>(V)) && V->hasName())
+ if (V->hasName())
Delete printname entirely.

The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.
llvm-svn: 30374
Close out this long standing bug by removing the remaining overloaded
virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.
llvm-svn: 29934
Add support for specifying alignment and size of setjmp jmpbufs.
No targets currently do anything with this information, nor is it presrved
in the bytecode representation. That's coming up next.

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/.

Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.

done by doubling up the data structures so that Type based equivalents are
used. A consequence of this is overloading of function members that take a
Type* instead of a Value*. Various other cleanups related to Type != Value
(bug 122) were also implemented.

such a way that if the Value being printed is standalone that we don't
assert and abort but just print ":??" for the slot number instead.

up restrictions on what can be put in SlotMachine (no Constants that aren't
GlobalValues).

incorporating a significantly simpler "SlotMachine" into this file. The
SlotMachine is tailored for use by only the AsmWriter whose requirements
for slot numbers are vastly different than from the Bytecode/Writer. Code
change passes all Feature and Regression tests.

* Make contained ostream pointer, not reference
* Allow setting of that ostream via setStream()
class CachedWriter:
* setStream() in turn calls setStream() on the AssemblyWriter

Since this really only makes sense for these two, change hte instance variable
to reflect whether we are writing a bytecode file or not. This makes it
reasonable to add bcwriter specific stuff to it as necessary.
