DylibFile needs to grow a 3rd constructor.

The only other interesting thing is that such an injected dylib
counts as a use of the original dylib. This patch gets this mostly
right (if _only_ `$ld$previous` symbols are used from a dylib,
we don't add a dep on the dylib itself, matching ld64), but one case
where we don't match ld64 yet is that ld64 even omits the original
dylib when linking it with `-needed-l`. Lld currently still adds a load

patch.)

Revert "[OpenMP] Remove noinline attributes in the device runtime"

The behaviour of this patch is not great, but it has some side-effects
that are required for OpenMPOpt to work. The problem is that when we use
`-mlink-builtin-bitcode` we only import used symbols from the runtime.
Then OpenMPOpt will insert calls to symbols that were not previously
included. This patch removed this implicit behaviour as these functions
were kept alive by the `noinline` simply because it kept calls to them
in the module. This caused regression in some tests that relied on some
OpenMPOpt passes without using LTO. Reverting for the LLVM15 release but
will try to fix it more correctly on main.

[ARM] Add target feature to force 32-bit atomics

This adds a +atomic-32 target feature, which instructs LLVM to assume
that lock-free 32-bit atomics are available for this target, even
if they usually wouldn't be.

If only atomic loads/stores are used, then this won't emit libcalls.
If atomic CAS is used, then the user is responsible for providing
any necessary __sync implementations (e.g. by masking interrupts
for single-core privileged use cases).

See https://reviews.llvm.org/D120026#3674333 for context on this
change. The tl;dr is that the thumbv6m target in Rust has
historically made atomic load/store only available, which is
incompatible with the change from D120026, which switched these to
use libatomic.

[Polly] Insert !dbg metadata for emitted CallInsts.

The IR Verifier requires that every call instruction to an inlineable
function (among other things, its implementation must be visible in the
translation unit) must also have !dbg metadata attached to it. When
parallelizing, Polly emits calls to OpenMP runtime function out of thin
air, or at least not directly derived from a bounded list of previous
instruction. While we could search for instructions in the SCoP that has
some debug info attached to it, there is no guarantee that we find any.
Our solution is to generate a new DILocation that points to line 0 to
represent optimized code.

The OpenMP function implementation is usually not available in the
user's translation unit, but can become visible in an LTO build. For
the bug to appear, libomp must also be built with debug symbols.

IMHO, the IR verifier rule is too strict. Runtime functions can
also be inserted by other optimization passes, such as
LoopIdiomRecognize. When inserting a call to e.g. memset, it uses the
DebugLoc from a StoreInst from the unoptimized code. It is not
required to have !dbg metadata attached either.

[mlir] Refactor SubElementInterface replace support

The current support was essentially the amount necessary
to support replacing SymbolRefAttrs, but suffers from various
deficiencies (both ergonomic and functional):

* Replace crashes if unsupported
 This makes it really hard to use safely, given that you don't know
 if you are going to crash or not when using it.

* Types aren't supported
This seems like a simple missed addition when the attribute replacement
support was originally added.

* The ergonomics are weird
It currently uses an index based replacement, which makes the implementations
quite clunky.

This commit refactors support to be a bit more ergonomic, and also
adds support for types in the process. This was also a great oppurtunity
to greatly simplify how replacement is done in the symbol table.

Sanjay Patel [Tue, 26 Jul 2022 19:31:12 +0000 (15:31 -0400)]
[AggressiveInstCombine] convert sqrt libcalls with "nnan" to sqrt intrinsics

This is an alternate to D129155 that uses TTI.haveFastSqrt() to avoid a
potential miscompile for programs with reads of errno. Moving the transform
to AggressiveInstCombine provides access to TTI.

If a sqrt call has "nnan", that implies that the input argument is never
negative because sqrt of {negative number} --> NAN.
If the argument is never negative and the call can be lowered without a
libcall, then we can assume that errno accesses are unchanged after lowering,
so the call can be translated to the LLVM intrinsic (which is expected to
become inline code).

This affects codegen for targets like x86 that have sqrt instructions, but
still have to conservatively assume that a libcall may be needed to set
errno as shown in issue #52620 and issue #56383.

This patch won't solve those examples - we will need to extend this to use
CannotBeOrderedLessThanZero or similar, enhance that analysis for new
operators, and/or deal with llvm.assume too.

[clang][dataflow] Analyze calls to in-TU functions

This patch adds initial support for context-sensitive analysis of simple functions whose definition is available in the translation unit, guarded by the `ContextSensitive` flag in the new `TransferOptions` struct. When this option is true, the `VisitCallExpr` case in the builtin transfer function has a fallthrough case which checks for a direct callee with a body. In that case, it constructs a CFG from that callee body, uses the new `pushCall` method on the `Environment` to make an environment to analyze the callee, and then calls `runDataflowAnalysis` with a `NoopAnalysis` (disabling context-sensitive analysis on that sub-analysis, to avoid problems with recursion). After the sub-analysis completes, the `Environment` from its exit block is simply assigned back to the environment at the callsite.

The `pushCall` method (which currently only supports non-method functions with some restrictions) maps the `SourceLocation`s for all the parameters to the existing source locations for the corresponding arguments from the callsite.

This patch adds a few tests to check that this context-sensitive analysis works on simple functions. More sophisticated functionality will be added later; the most important next step is to explicitly model context in some fields of the `DataflowAnalysisContext` class, as mentioned in a `FIXME` comment in the `pushCall` implementation.

[clang][dataflow] Analyze calls to in-TU functions

Depends On D130305

This patch adds initial support for context-sensitive analysis of simple functions whose definition is available in the translation unit, guarded by the `ContextSensitive` flag in the new `TransferOptions` struct. When this option is true, the `VisitCallExpr` case in the builtin transfer function has a fallthrough case which checks for a direct callee with a body. In that case, it constructs a CFG from that callee body, uses the new `pushCall` method on the `Environment` to make an environment to analyze the callee, and then calls `runDataflowAnalysis` with a `NoopAnalysis` (disabling context-sensitive analysis on that sub-analysis, to avoid problems with recursion). After the sub-analysis completes, the `Environment` from its exit block is simply assigned back to the environment at the callsite.

The `pushCall` method (which currently only supports non-method functions with some restrictions) first calls `initGlobalVars`, then maps the `SourceLocation`s for all the parameters to the existing source locations for the corresponding arguments from the callsite.

This patch adds a few tests to check that this context-sensitive analysis works on simple functions. More sophisticated functionality will be added later; the most important next step is to explicitly model context in some fields of the `DataflowAnalysisContext` class, as mentioned in a `TODO` comment in the `pushCall` implementation.

[MachineFunctionPass] Support -print-changed and -print-changed=quiet

-print-changed for new pass manager is handy beside -print-after-all.
Port it to MachineFunctionPass.

Note: lib/Passes/StandardInstrumentations.cpp implements a number of
misc features. If we want to use them for codegen, we may need to lift
some functionality to LLVMIR.
