[FileCheck] Simplify numeric variable interface

Summary:
This patch simplifies 2 aspects in the FileCheckNumericVariable code.

First, setValue() method is turned into a void function since being
called only on undefined variable is an invariant and is now asserted
rather than returned. This remove the assert from the callers.

Second, clearValue() method is also turned into a void function since
the only caller does not check its return value since it may be trying
to clear the value of variable that is already cleared without this
being noteworthy.

after substitutions are made, if any. However, when a substitution

[CMake] `install-distribution` for LLDB on Darwin

Summary:
There's a number of requirements for installing LLDB on macOS that are untypical for LLVM projects: use special install-prefix for LLDB.framework, ship headers and tools as framework resources, patch RPATHs, externalize debug-info to dSYM's and strip binaries with `-ST`. For some of it we could use `llvm_externalize_debuginfo()` in the past and just add special cases. However, this complicates the code for all projects and comes with the major drawback, that it adds all these actions at build-time, i.e. dSYM creation and stripping take a lot of time and don't make sense at build-time.

LLVM's distribution mechanism (https://llvm.org/docs/BuildingADistribution.html) appears to be the natural candidate to install LLDB. Based on D64399 (enable in standalone builds), this patch integrates framework installation with the distribution mechanism and adds custom stripping flags and dSYM creation at install-time. Unlike the abandoned D61952, it leaves build-tree binaries untouched, so there's no side-effects on testing. Potential install-order issues must be handled externally.

Please let me know what you think, while I run a few more tests and add remarks+documentation.

Rui Ueyama [Wed, 10 Jul 2019 05:00:37 +0000 (05:00 +0000)]
[Coding style change] Rename variables so that they start with a lowercase letter

This patch is mechanically generated by clang-llvm-rename tool that I wrote
using Clang Refactoring Engine just for creating this patch. You can see the
source code of the tool at https://reviews.llvm.org/D64123. There's no manual
post-processing; you can generate the same patch by re-running the tool against
lld's code base.

Here is the main discussion thread to change the LLVM coding style:
https://lists.llvm.org/pipermail/llvm-dev/2019-February/130083.html
In the discussion thread, I proposed we use lld as a testbed for variable
naming scheme change, and this patch does that.

I chose to rename variables so that they are in camelCase, just because that
is a minimal change to make variables to start with a lowercase letter.

Note to downstream patch maintainers: if you are maintaining a downstream lld
repo, just rebasing ahead of this commit would cause massive merge conflicts
because this patch essentially changes every line in the lld subdirectory. But
there's a remedy.

clang-llvm-rename tool is a batch tool, so you can rename variables in your
downstream repo with the tool. Given that, here is how to rebase your repo to
a commit after the mass renaming:

1. rebase to the commit just before the mass variable renaming,
2. apply the tool to your downstream repo to mass-rename variables locally, and
3. rebase again to the head.

Most changes made by the tool should be identical for a downstream repo and
for the head, so at the step 3, almost all changes should be merged and
disappear. I'd expect that there would be some lines that you need to merge by
hand, but that shouldn't be too many.

[Support] Move llvm::MemoryBuffer to sys::fs::file_t

Summary:
On Windows, Posix integer file descriptors are a compatibility layer
over native file handles provided by the C runtime. There is a hard
limit on the maximum number of file descriptors that a process can open,
and the limit is 8192. LLD typically doesn't run into this limit because
it opens input files, maps them into memory, and then immediately closes
the file descriptor. This prevents it from running out of FDs.

For various reasons, I'd like to open handles to every input file and
keep them open during linking. That requires migrating MemoryBuffer over
to taking open native file handles instead of integer FDs.

Peter Collingbourne [Tue, 9 Jul 2019 20:22:36 +0000 (20:22 +0000)]
hwasan: Improve precision of checks using short granule tags.

A short granule is a granule of size between 1 and `TG-1` bytes. The size
of a short granule is stored at the location in shadow memory where the
granule's tag is normally stored, while the granule's actual tag is stored
in the last byte of the granule. This means that in order to verify that a
pointer tag matches a memory tag, HWASAN must check for two possibilities:

* the pointer tag is equal to the memory tag in shadow memory, or
* the shadow memory tag is actually a short granule size, the value being loaded
  is in bounds of the granule and the pointer tag is equal to the last byte of
  the granule.

Pointer tags between 1 to `TG-1` are possible and are as likely as any other
tag. This means that these tags in memory have two interpretations: the full
tag interpretation (where the pointer tag is between 1 and `TG-1` and the
last byte of the granule is ordinary data) and the short tag interpretation
(where the pointer tag is stored in the granule).

When HWASAN detects an error near a memory tag between 1 and `TG-1`, it
will show both the memory tag and the last byte of the granule. Currently,
it is up to the user to disambiguate the two possibilities.

Because this functionality obsoletes the right aligned heap feature of
the HWASAN memory allocator (and because we can no longer easily test
it), the feature is removed.

Also update the documentation to cover both short granule tags and
outlined checks.

allowsMemoryAccess on certain CPUs due to slow unaligned memory
subtarget features. This prevents bitcasts from being folded into
loads and stores. But all vector loads and stores of the same width
are the same cost on X86.

This patch merges the allowsMemoryAccess call into isLoadBitCastBeneficial to allow X86 to skip it.

5 years agoAdd a transform pass to make the executable semantics of poison explicit in the IR
Philip Reames [Tue, 9 Jul 2019 18:49:29 +0000 (18:49 +0000)]
Add a transform pass to make the executable semantics of poison explicit in the IR

Implements a transform pass which instruments IR such that poison semantics are made explicit. That is, it provides a (possibly partial) executable semantics for every instruction w.r.t. poison as specified in the LLVM LangRef. There are obvious parallels to the sanitizer tools, but this pass is focused purely on the semantics of LLVM IR, not any particular source language.

The target audience for this tool is developers working on or targetting LLVM from a frontend. The idea is to be able to take arbitrary IR (with the assumption of known inputs), and evaluate it concretely after having made poison semantics explicit to detect cases where either a) the original code executes UB, or b) a transform pass introduces UB which didn't exist in the original program.

At the moment, this is mostly the framework and still needs to be fleshed out. By reusing existing code we have decent coverage, but there's a lot of cases not yet handled. What's here is good enough to handle interesting cases though; for instance, one of the recent LFTR bugs involved UB being triggered by integer induction variables with nsw/nuw flags would be reported by the current code.

[clangd] Rewrite of logic to rebuild the background index serving structures.

Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough
   to pass the tests). Instead, we expose the rebuilder as a separate class and
   have fine-grained tests for it.
