2009-07-20Add plumbing for the `linker_private' linkage type. This type is meant forBill Wendling
"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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76385 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-08Remove the vicmp and vfcmp instructions. Because we never had a release withNick Lewycky
these instructions, no autoupgrade or backwards compatibility support is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74991 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-02Restore other bits of the C API that I tore up. All pre-existing APIs ↵Owen Anderson
default to using the default global context, while new *InContext() APIs have been added that take a LLVMContextRef parameter. Apologies to anyone affected by this breakage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74694 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Make the use of const with respect to LLVMContext sane. Hopefully this is ↵Owen Anderson
the last time, for the moment, that I will need to make far-reaching changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74655 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-01Add a pointer to the owning LLVMContext to Module. This requires threading ↵Owen Anderson
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74614 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16Fix PR4336: Iterating over use-def chains doesn't seem to be deterministic.Chris Lattner
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! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73470 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Split the Add, Sub, and Mul instruction opcodes into separateDan Gohman
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: http://nondot.org/sabre/LLVMNotes/IntegerOverflow.txt git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72897 91177308-0d34-0410-b5e6-96231b3b80d8

Constant* in preperation of a future change to support holding non-Constants in an MDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71407 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Make a major API change to BitstreamReader: split all the readingChris Lattner
state out of the BitstreamReader class into a BitstreamCursor class. Doing this allows the client to have multiple cursors into the same file, each with potentially different live block stacks and abbreviation records. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70157 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Add a new "available_externally" linkage type. This is intendedChris Lattner
to support C99 inline, GNU extern inline, etc. Related bugzilla's include PR3517, PR3100, & PR2933. Nothing uses this yet, but it appears to work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68940 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-04Add support for embedded metadata to LLVM. This introduces two new types ofNick Lewycky
Constant, MDString and MDNode which can only be used by globals with a name that starts with "llvm." or as arguments to a function with the same naming restriction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68420 91177308-0d34-0410-b5e6-96231b3b80d8

it be an LLVM IR User object. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68156 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-23Fix internal representation of fp80 to be theDale Johannesen
same as a normal i80 {low64, high16} rather than its own {high64, low16}. A depressing number of places know about this; I think I got them all. Bitcode readers and writers convert back to the old form to avoid breaking compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67562 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11It makes no sense to have a ODR version of commonDuncan Sands
linkage, so remove it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66690 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11Remove the one-definition-rule version of extern_weakDuncan Sands
linkage: this linkage type only applies to declarations, but ODR is only relevant to globals with definitions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66650 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-15Introducing nocapture, a parameter attribute for pointers to indicate that theNick Lewycky
callee will not introduce any new aliases of that pointer. The attributes had all bits allocated already, so I decided to collapse alignment. Alignment was previously stored as a 16-bit integer from bits 16 to 32 of the attribute, but it was required to be a power of 2. Now it's stored in log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of space. You may have already noticed that you only need four bits to encode a 16-bit power of two, so why five bits? Because the AsmParser accepted 32-bit alignments, even though we couldn't store them (they were silently discarded). Now we can store them in memory, but not in the bitcode. The bitcode format was already storing these as 64-bit VBR integers. So, the bitcode format stays the same, keeping the alignment values stored as 16 bit raw values. There's some hideous code in the reader and writer that deals with this, waiting to be ripped out the moment we run out of bits again and have to replace the parameter attributes table encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61019 91177308-0d34-0410-b5e6-96231b3b80d8
