The LLVM compiler infrastructure supports a wide range of projects, from

|
|
|
|
industrial strength compilers to specialized JIT applications to small
|
|
|
|
|
research projects.
|
|
|
|
|
|
|
|
|
|
Similarly, documentation is broken down into several high-level groupings

NOTE: If you are a user who is only interested in using an LLVM-based compiler,
|
|
|
|
|
you should look into `Clang <http://clang.llvm.org>`_ instead. The
|
|
|
|
|
documentation here is intended for users who have a need to work with the
|
|
|
|
|
intermediate LLVM representation.

HowToBuildOnARM
|
Add docs+a script for building clang/LLVM with PGO
Depending on who you ask, PGO grants a 15%-25% improvement in build
times when using clang. Sadly, hooking everything up properly to
generate a profile and apply it to clang isn't always straightforward.
This script (and the accompanying docs) aim to make this process easier;
ideally, a single invocation of the given script.
In terms of testing, I've got a cronjob on my Debian box that's meant to
run this a few times per week, and I tried manually running it on a puny
Gentoo box I have (four whole Atom cores!). Nothing obviously broke.
¯\_(ツ)_/¯
I don't know if we have a Python style guide, so I just shoved this
through yapf with all the defaults on.
Finally, though the focus is clang at the moment, the hope is that this
is easily applicable to other LLVM-y tools with minimal effort (e.g.
lld, opt, ...). Hence, this lives in llvm/utils and tries to be somewhat
ambiguous about naming.

IR: New representation for CFI and virtual call optimization pass metadata.
The bitset metadata currently used in LLVM has a few problems:
1. It has the wrong name. The name "bitset" refers to an implementation
detail of one use of the metadata (i.e. its original use case, CFI).
This makes it harder to understand, as the name makes no sense in the
context of virtual call optimization.
2. It is represented using a global named metadata node, rather than
being directly associated with a global. This makes it harder to
manipulate the metadata when rebuilding global variables, summarise it
as part of ThinLTO and drop unused metadata when associated globals are
dropped. For this reason, CFI does not currently work correctly when
both CFI and vcall opt are enabled, as vcall opt needs to rebuild vtable
globals, and fails to associate metadata with the rebuilt globals. As I
understand it, the same problem could also affect ASan, which rebuilds
globals with a red zone.
This patch solves both of those problems in the following way:
1. Rename the metadata to "type metadata". This new name reflects how
the metadata is currently being used (i.e. to represent type information
for CFI and vtable opt). The new name is reflected in the name for the
associated intrinsic (llvm.type.test) and pass (LowerTypeTests).
2. Attach metadata directly to the globals that it pertains to, rather
than using the "llvm.bitsets" global metadata node as we are doing now.
This is done using the newly introduced capability to attach
metadata to global variables (r271348 and r271358).

TypeMetadata

[Unroll/UnrollAndJam/Vectorizer/Distribute] Add followup loop attributes.
When multiple loop transformation are defined in a loop's metadata, their order of execution is defined by the order of their respective passes in the pass pipeline. For instance, e.g.
#pragma clang loop unroll_and_jam(enable)
#pragma clang loop distribute(enable)
is the same as
#pragma clang loop distribute(enable)
#pragma clang loop unroll_and_jam(enable)
and will try to loop-distribute before Unroll-And-Jam because the LoopDistribute pass is scheduled after UnrollAndJam pass. UnrollAndJamPass only supports one inner loop, i.e. it will necessarily fail after loop distribution. It is not possible to specify another execution order. Also,t the order of passes in the pipeline is subject to change between versions of LLVM, optimization options and which pass manager is used.
This patch adds 'followup' attributes to various loop transformation passes. These attributes define which attributes the resulting loop of a transformation should have. For instance,
!0 = !{!0, !1, !2}
!1 = !{!"llvm.loop.unroll_and_jam.enable"}
!2 = !{!"llvm.loop.unroll_and_jam.followup_inner", !3}
!3 = !{!"llvm.loop.distribute.enable"}
defines a loop ID (!0) to be unrolled-and-jammed (!1) and then the attribute !3 to be added to the jammed inner loop, which contains the instruction to distribute the inner loop.
Currently, in both pass managers, pass execution is in a fixed order and UnrollAndJamPass will not execute again after LoopDistribute. We hope to fix this in the future by allowing pass managers to run passes until a fixpoint is reached, use Polly to perform these transformations, or add a loop transformation pass which takes the order issue into account.
For mandatory/forced transformations (e.g. by having been declared by #pragma omp simd), the user must be notified when a transformation could not be performed. It is not possible that the responsible pass emits such a warning because the transformation might be 'hidden' in a followup attribute when it is executed, or it is not present in the pipeline at all. For this reason, this patche introduces a WarnMissedTransformations pass, to warn about orphaned transformations.
Since this changes the user-visible diagnostic message when a transformation is applied, two test cases in the clang repository need to be updated.
To ensure that no other transformation is executed before the intended one, the attribute `llvm.loop.disable_nonforced` can be added which should disable transformation heuristics before the intended transformation is applied. E.g. it would be surprising if a loop is distributed before a #pragma unroll_and_jam is applied.
With more supported code transformations (loop fusion, interchange, stripmining, offloading, etc.), transformations can be used as building blocks for more complex transformations (e.g. stripmining+stripmining+interchange -> tiling).

Community
|
|
|
|
|
=========
|
|
|
|
|
|
|
|
|
|
LLVM has a thriving community of friendly and helpful developers.
|
|
|
|
|
The two primary communication mechanisms in the LLVM community are mailing
|
|
|
|
|
lists and IRC.

`Developer's List (llvm-dev)`__
|
2013-01-20 03:19:36 +01:00
|
|
|
|
This list is for people who want to be included in technical discussions of
|
|
|
|
|
LLVM. People post to this list when they have questions about writing code
|
|
|
|
|
for or using the LLVM tools. It is relatively low volume.

This list contains all commit messages that are made when LLVM developers
|
2013-03-30 16:33:02 +01:00
|
|
|
|
commit code changes to the repository. It also serves as a forum for
|
|
|
|
|
patch review (i.e. send patches here). It is useful for those who want to
|
|
|
|
|
stay on the bleeding edge of LLVM development. This list is very high
|
|
|
|
|
volume.
