2012-12-07docs: Convert LangRef to reST.Sean Silva
NOTE: If you have any patches in the works that modify LangRef, you will need to rewrite the changes to LangRef.html to their equivalents in LangRef.rst. If you need assistance feel free to contact me. Since LangRef is mission-critical for the project and "normative", I have taken extra care to ensure that no content was lost or altered in the conversion. The content was converted with a tool called `pandoc`, so there is no chance for a human error like accidentally forgetting a sentence or whatever. After the initial conversion by `pandoc`, only changes to the markup were done. This is just the most literal conversion of the HTML document as possible. It might be worth exploring some way to chop up this massive document into separate pages, e.g. something like `docs/LangRef/Instructions.rst`, `docs/LangRef/Intrinsics.rst`, etc. with `docs/LangRef.rst` being an "intro/navigation page" of sorts. On the other hand, that loses the ability to {Ctrl,Cmd}-F for a given term right from your browser. IMO, I think our stylesheet needs some work because I find it hard to tell what level of nesting some of the headings are at (e.g. "is this a new section or is it a subsection?"). The issue is present on other pages, but the sheer size and deep section structure of LangRef really brings this issue out. If there are any web designers out there in the community it would be awesome if you tried to come up with something nicer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169596 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-13Relax the restrictions on vector of pointer types, and vector getelementptr.Duncan Sands
Previously in a vector of pointers, the pointer couldn't be any pointer type, it had to be a pointer to an integer or floating point type. This is a hassle for dragonegg because the GCC vectorizer happily produces vectors of pointers where the pointer is a pointer to a struct or whatever. Vector getelementptr was restricted to just one index, but now that vectors of pointers can have any pointer type it is more natural to allow arbitrary vector getelementptrs. There is however the issue of struct GEPs, where if each lane chose different struct fields then from that point on each lane will be working down into unrelated types. This seems like too much pain for too little gain, so when you have a vector struct index all the elements are required to be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167828 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-17Change the `linker_private_weak_def_auto' linkage to `linkonce_odr_auto_hide' toBill Wendling
make it more consistent with its intended semantics. The `linker_private_weak_def_auto' linkage type was meant to automatically hide globals which never had their addresses taken. It has nothing to do with the `linker_private' linkage type, which outputs the symbols with a `l' (ell) prefix among other things. The intended semantic is more like the `linkonce_odr' linkage type. Change the name of the linkage type to `linkonce_odr_auto_hide'. And therefore changing the semantics so that it produces the correct output for the linker. Note: The old linkage name `linker_private_weak_def_auto' will still parse but is not a synonym for `linkonce_odr_auto_hide'. This should be removed in 4.0. <rdar://problem/11754934> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162114 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-10[ms-inline asm] Add a new Inline Asm Non-Standard Dialect attribute.Chad Rosier
This new attribute is intended to be used by the backend to determine how the inline asm string should be parsed/printed. This patch adds the ia_nsdialect attribute and also adds a test case to ensure the IR is correctly parsed, but there is no functional change at this time. The standard dialect is assumed to be AT&T. Therefore, this attribute should only be added to MS-style inline assembly statements, which use the Intel dialect. If we ever support more dialects we'll need to add additional state to the attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161641 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-23Extend the IL for selecting TLS models (PR9788)Hans Wennborg
This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159077 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-05Add a new intrinsic: llvm.fmuladd. This intrinsic represents a multiply-addLang Hames
expression (a * b + c) that can be implemented as a fused multiply-add (fma) if the target determines that this will be more efficient. This intrinsic will be used to implement FP_CONTRACT support and an aggressive FMA formation mode. If your target has a fast FMA instruction you should override the isFMAFasterThanMulAndAdd method in TargetLowering to return true. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158014 91177308-0d34-0410-b5e6-96231b3b80d8

be non contiguous, non overlapping and sorted by the lower end.

2012-04-16Make it possible to indicate relaxed floating point requirements at the IR levelDuncan Sands
through the use of 'fpmath' metadata. Currently this only provides a 'fpaccuracy' value, which may be a number in ULPs or the keyword 'fast', however the intent is that this will be extended with additional information about NaN's, infinities etc later. No optimizations have been hooked up to this so far. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154822 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-14Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'mDuncan Sands
thinking of generalizing it to be able to specify other freedoms beyond accuracy (such as that NaN's don't have to be respected). I'd like the 3.1 release (the first one with this metadata) to have the more generic name already rather than having to auto-upgrade it in 3.2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154744 91177308-0d34-0410-b5e6-96231b3b80d8
