* [LangRef] Improve llvm.mem.parallel_loop_access exampleTobias Grosser2014-03-05
| | | | | | | | | | | | | | | | | | | | The following changes have been applied: - Removed 'align 4'. We can simplify this away, as it does not provide useful information in the example. - Use named instructions instead of '%0'. This is nicer, but more importantly this makes the IR valid. Before we had two assignments to %0 in a single example. - Add a missing branch instruction to make the loop structure clear. - Move one access into outer.for.body to make it not look that empty. - The statments that are only in the outer loop body should not reference the inner loop metadata, but only the outer loop. Only statements in both loops should reference both surrounding loops. - Rename the array indexes to make them all independent. Before there were identical array indexes in the inner and the outer loop. We want to avoid this special case as it may lead to confusion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202973 91177308-0d34-0410-b5e6-96231b3b80d8
* Change x86mmx -> x86_mmx in LangRef.rstReid Kleckner2014-03-05
| | | | | | | | | | | The correct name of the type in LLVM assembly is "x86_mmx". Also remove the reST label "t_x86mmx" because it was unused anyway. Patch by Manuel Jacob!

* [Modules] Move ValueMap to the IR library. While this class does notChandler Carruth2014-03-04
| | | | | | | | | | | | directly care about the Value class (it is templated so that the key can be any arbitrary Value subclass), it is in fact concretely tied to the Value class through the ValueHandle's CallbackVH interface which relies on the key type being some Value subclass to establish the value handle chain.

* C++11: Beware unnecessary copies with autoDuncan P. N. Exon Smith2014-03-03

* [docs] Add a section to the coding standards about languages and such.Chandler Carruth2014-02-28
| | | | | | | | | | | | | | | | A lot of this is writing down common knowledge and things often communicated on mailing lists and in discussions. It could live in the Programmer's Manual alternatively, but that felt slightly less well-fitting. It also includes (and was motivated by) the section on the relevant language standards for LLVM and the specific features that will be enabled with the switch to C++11. With this, all of the documentation for the C++11 switch is, I think, in place.

It claims the document intentionally doesn't give fixed standards for brace placement or spacing, and then the document goes on to do precisely that in several places. Instead, try to highlight that even these rules are simply *guidance* which may be trumped by some other circumstance or the local conventions of code.

Also, there are many other ways to get at the trunk source (git, git-svn, etc). The TeXinfo thing... I have no idea about. But you can get a working LLVM w/o it pretty easily. If man pages or something are missing, that hardly seems like a problem. If folks really want this back, let me know, but it seems mostly like a distraction. I'd still like to separate this into: - Required software to compile. - Optional software to compile. - Required software for certain *contributor* activities (like regenerating configure scripts). Also we need to mention that there are multiple options for build systems, and the differences. Also we should mention Windows. Also probably other stuff I'm forgetting. I'm wondering if this whole thing needs to be shot in the head and we should just start a new, simpler getting started that doesn't have so many years of accumulated stuff that is no longer relevant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202373 91177308-0d34-0410-b5e6-96231b3b80d8

Really? - Xcode 2.5 and gcc 4.0.1 are really not a concern -- they don't work. - OMG, we actually tried building LLVM on Alpha? Really? - PowerPC works pretty well these days. There is still a lot of stuff here I'm pretty dubious about, but I nuked most of what was actively misleading, out of date, or patently wrong. Some of it (mingw stuff especially) isn't really lacking, its just that the comments here were actively wrong.

| | | | | | | | | | | | | | | | | | | | | | | | | | | They're called code fragments, but they are really multiline string literals. Just spotted this usage in a patch by Aaron using "code fragments" for holding documentation text. I remember someone bemoaning the lack of multiline string literals in TableGen, so I'm explicitly documenting that code fragments are multiline string literals. Let it be known that any use case needing multiline string literals in TableGen (such as descriptions of options, or whatnot) can use use code fragments (instead of C-style string concatenation or exceedingly long lines). E.g. class Bar<int n>; class Baz<int n>; class Doc<string desc> { string Desc = desc; } def Foo : Bar<1>, Baz<3>, Doc<[{ This Foo is a Bar, and also a Baz.
