Owen Anderson edb4a70325 Revert the ConstantInt constructors back to their 2.5 forms where possible, thanks to contexts-on-types. More to come.

Devang Patel 6292003492 MDString
- Rename member function size(). New name is length().
- Store string beginning and length. Earlier it used to store string end.

Devang Patel e059ba6ed2 Derive MDNode from MetadataBase instead of Constant. Emit MDNodes into METADATA_BLOCK in bitcode file.

Devang Patel 7428d8acec Introduce MetadataBase, a base class for MDString and MDNode.
Derive MDString directly from MetadataBase. 
Introduce new bitcode block to hold metadata.

Bill Wendling a3c6f6bffa Add plumbing for the `linker_private' linkage type. This type is meant for
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Owen Anderson 1e5f00e7a7 This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

Owen Anderson b17f32945f Switch GlobalVariable ctors to a sane API, where *either* a context or a module is required.

Nick Lewycky a21d3daadc Remove the vicmp and vfcmp instructions. Because we never had a release with
these instructions, no autoupgrade or backwards compatibility support is
provided.

Owen Anderson 2a15443aa8 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the
moment, that I will need to make far-reaching changes.

Owen Anderson 1cf085d558 Hold the LLVMContext by reference rather than by pointer.

2009-07-01 21:22:36 +00:00
Owen Anderson 6773d388aa Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

Chris Lattner 06310bf178 Fix PR4336: Iterating over use-def chains doesn't seem to be deterministic.
The problem was that BitcodeReader::materializeModule would read functions
from the bc file in densemap pointer key order (doubly non-deterministic!),
which would cause the use-def chains to be set up for globals in
non-determinstic order.  Non-determinstic use/def chains can cause 
nondeterminism in many places down-stream.

Many thanks to Julien Lerouge for putting together the pass in the PR that
shows the issue!

Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Nick Lewycky cb8317dac9 Update the bitcode reader to support reading .bc files where the embedded
metadata references non-Constant values such as instructions.

Nick Lewycky b8f9b7a965 Make MDNode use CallbackVH. Also change MDNode to store Value* instead of
Constant* in preperation of a future change to support holding non-Constants
in an MDNode.
