AMDGPU/SI: Use a better method for determining the largest pressure sets

Summary:
There are a few different sgpr pressure sets, but we only care about
the one which covers all of the sgprs.  We were using hard-coded
register pressure set names to determine the reg set id for the
biggest sgpr set.  However, we were using the wrong name, and this
method is pretty fragile, since the reg pressure set names may
change.

The new method just looks for the pressure set that contains the most
reg units and sets that set as our SGPR pressure set.  We've also
adopted the same technique for determining our VGPR pressure set.

8 years ago[CMake] Connect Compiler-RT targets to LLVM Runtimes directory
Chris Bieneman [Fri, 26 Aug 2016 20:52:22 +0000 (20:52 +0000)]
[CMake] Connect Compiler-RT targets to LLVM Runtimes directory

This patch builds on LLVM r279776.

In this patch I've done some cleanup and abstracted three common steps runtime components have in their CMakeLists files, and added a fourth.

The three steps I abstract are:

(1) Add a top-level target (i.e asan, msan, ...)
(2) Set the target properties for sorting files in IDE generators
(3) Make the compiler-rt target depend on the top-level target

The new step is to check if a command named "runtime_register_component" is defined, and to call it with the component name.

The runtime_register_component command is defined in llvm/runtimes/CMakeLists.txt, and presently just adds the component to a list of sub-components, which later gets used to generate target mappings.

With this patch a new workflow for runtimes builds is supported. The new workflow when building runtimes from the LLVM runtimes directory is:

> cmake [...]
> ninja runtimes-configure
> ninja asan

The "runtimes-configure" target builds all the dependencies for configuring the runtimes projects, and runs CMake on the runtimes projects. Running the runtimes CMake generates a list of targets to bind into the top-level CMake so subsequent build invocations will have access to some of Compiler-RT's targets through the top-level build.

Note: This patch does exclude some top-level targets from compiler-rt libraries because they either don't install files (sanitizer_common), or don't have a cooresponding `check` target (stats).

Summary:
This commit sets up the infrastructure to use reified error
descriptions, and moves ReportStackOverflow to the new system.

After we convert all the errors, we'll be able to simplify ScopedInErrorReport

in some way. We'll be able to maintain the external API.

ScopedInErrorReport will be able to track one of the reified errors at a time.
The purpose of this is so we have its destructor actually print the error and

Summary:
This is obviously an interesting case because it may motivate code

Reporting this requires instantiation of ORE in the loop where the call

overhead *with* -Rpass-with-hotness and the worst slow-down was 6% in
mcf and quickly tailing off.  As before without -Rpass-with-hotness
there is no overhead.

Because this could be a pretty noisy diagnostics, it is currently
qualified as 'verbose'.  As of this patch, 'verbose' diagnostics are
only emitted with -Rpass-with-hotness, i.e. when the output is expected
to be filtered.

Handle empty functions with debug info in load/store opt pass

Summary:
In fuctions that contained debug info but were empty otherwise,
the ARM load/store optimizer could abort. This was because
function MergeReturnIntoLDM handled the special case where a
Machine Basic BLock is empty by calling MBB.empty(). However, this
returns false in presence of debug info, although the function
should be considered empty in the eyes of the load/store optimizer.
This has been fixed by handling the case where searching through the
block finds only debug instructions.

We also make the implementation easier to read by removing integer wrappig in
abs() when passing in the minimal integer value for a given bitwidth. Even
though wrapping and subsequently interpreting the result as unsigned value gives
the correct result, this is far from obvious.  Instead, we explicitly add one
more bit to the input type to ensure that abs will never wrap. This change did
not uncover a bug in the old implementation, but was introduced to increase
readability.

We update the tests to add a test case for this special case and use this
opportunity to also test a number larger than 64 bit. Finally, we order the

Add cmake option to choose whether to use the builtin demangler

Summary:
Previously the builting demangler was on for platforms that explicitly set a flag by modifying
Mangled.cpp (windows, freebsd). The Xcode build always used builtin demangler by passing a
compiler flag. This adds a cmake flag (defaulting to ON) to configure the demangling library used
at build time. The flag is only available on non-windows platforms as there the system demangler
is not present (in the form we're trying to use it, at least).
The impact of this change is:
- linux: switches to the builtin demangler
- freebsd, windows: NFC (I hope)
- netbsd: switches to the builtin demangler
- osx cmake build: switches to the builtin demangler (matching the XCode build)

The main motivation for this is the cross-platform case, where it should bring more consistency
by removing the dependency on the host demangler (which can be completely unrelated to the debug
target).

records to be written to the log in subsequent changes. It also defines the format
that the function call accounting tool in D21987 will start building upon.

Once D21987 lands, we should be able to start defining more tests using that tool

[CMake] Add support for exposing runtime targets

This patch adds support to the runtimes build for exposing sub-project targets through the high-level configuration. This will enable exposing the build, check and install targets for sub-project components (i.e. asan, check-asan, install-asan...).

This patch requires minor changes to the runtime projects to take advantage of it, and I'll phase those changes into Compiler-RT shortly.

8 years agoARM: by default don't set the Thumb bit on MachO relocated values.

ARM: by default don't set the Thumb bit on MachO relocated values.

Its existence is largely historical, apparently we tried to make ARM object
files look maybe-almost-possibly runnable by putting our best guess at the
actual value into relocated locations. Of course, the real linker then comes
along and can completely change things.

But it should only be there for word-sized and movw/movt relocations. It can't
be encoded in branch relocations, and I've seen it mess up validity
calculations twice in the last couple of weeks so the default is clearly problematic.
