C bindings for libLLVMCore.a and libLLVMBitWriter.a.
...
- The naming prefix is LLVM.
- All types are represented using opaque references.
- Functions are not named LLVM{Type}{Method}; the names became
unreadable goop. Instead, they are named LLVM{ImperativeSentence}.
- Where an attribute only appears once in the class hierarchy (e.g.,
linkage only applies to values; parameter types only apply to
function types), the class is omitted from identifiers for
brevity. Tastes like methods.
- Strings are C strings or string/length tuples on a case-by-case
basis.
- APIs which give the caller ownership of an object are not mapped
(removeFromParent, certain constructor overloads). This keeps
keep memory management as simple as possible.
For each library with bindings:
llvm-c/<LIB>.h - Declares the bindings.
lib/<LIB>/<LIB>.cpp - Implements the bindings.
So just link with the library of your choice and use the C header
instead of the C++ one.

This occurs in the example in PR1602. With this fixed, we now compile

define void @_Z1g1S(%struct.S* noalias %s) {
entry: %tmp131415 = getelementptr %struct.S* %s, i32 0, i32 0 ; <i32 (...)***> [#uses=1] %tmp16 = load i32 (...)*** %tmp131415, align 4 ; <i32 (...)**> [#uses=1]
%tmp26277 = load i32 (...)** %tmp16 ; <i32 (...)*> [#uses=1]
%tmp2829 = bitcast i32 (...)* %tmp26277 to void (%struct.S*)* ; <void (%struct.S*)*> [#uses=1]
tail call void %tmp2829( %struct.S* %s )

}

Patch 10 for long double. Doing constants right needs expanding ConstantFP
...
to handle values bigger than double. If we assume host==target and host
long double works correctly, this is not too bad, but we don't want to
have that limitation longterm. I could implement accepting double
constants as long double or something like that, which would lead to
incorrect codegen with no errors; the more I think about that the worse
it seems. Rather than do such a hack that would be backed out later,
I'm settling for giving reasonable error messages, for now.

1. domtree is a tree, not a graph. There is no need to avoid revisiting nodes with a set.
2. the worklist can contain the child iterator pointers so we don't get N^2 rescanning of children.
This speeds up updateDFSNumbers significantly, making it basically free. On the testcase in PR1432,

As the number of parameter attributes increases,
...
Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes. This patch tidies the whole thing up
using attribute masks. While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail. Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).

lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.
This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.

merge several fields in GlobalValue to use the same word, move CallingConv
...
field into SubclassData in Value. This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68. This trims
4640 bytes off my testcase, reading a bc file without materializing any
functions.

The (negative) offset from a SymbolTableListTraits-using ilist to its container
...
object is always constant. As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits. This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

Refactor SymbolTableListTraits to only have a single pointer in it, instead
...
of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60). On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.
