Remove C APIs for interacting with PassRegistry and pass
initialization. These are legacy PM concepts, and are no longer
relevant for the new pass manager.
Calls to these initialization functions can simply be dropped.

The legacy PM is only supported for codegen, and PassManagerBuilder
is exclusively about the middle-end optimization pipeline. Drop it.

Legacy passes are only supported for codegen, and I don't believe
it's possible to write backends using the C API, so we should drop
all of those. Reduces the number of places that need to be modified

Fixes https://github.com/llvm/llvm-project/issues/56496.
As mentioned in the issue, new functions LLVMArrayType2 and
LLVMGetArrayLength2 are created so as to not break the old API.
The old methods are then marked as deprecated and callers are

I'm working on a tool that visits debug info and massages it using the
llvm-c API. I noticed that LLVMGetOperand special cases MDNodes so I
can get their operands, but I can't replace them. This patch adds
LLVMReplaceMDNodeOperandWith which boils down to
MDNode::replaceOperandWith.
The name was chosen for consistency with LLVMGetMDNodeOperands and
LLVMGetMDNodeNumOperands.

Target-extension types represent types that need to be preserved through
optimization, but otherwise are not introspectable by target-independent
optimizations. This patch doesn't add any uses of these types by an existing
backend, it only provides basic infrastructure such that these types would work
correctly.

Not deleting the loose instruction with metadata associated to it causes

This adds LLVMGetAggregateElement() as a wrapper for
Constant::getAggregateElement(), which allows fetching a
struct/array/vector element without handling different possible
underlying representations.
As the changed echo test shows, previously you for example had to
treat ConstantArray (use LLVMGetOperand) and ConstantDataArray
(use LLVMGetElementAsConstant) separately, not to mention all the
other possible representations (like PoisonValue).
I've deprecated LLVMGetElementAsConstant() in favor of the new
function, which is strictly more powerful (but I could be convinced
to drop the deprecation).
This is partly motivated by https://reviews.llvm.org/D125795,
which drops LLVMConstExtractValue() because the underlying constant
expression no longer exists. This function could previously be used
as a poor man's getAggregateElement().

Avoid a behavior change when opaque pointers are enabled by default.
|
|
This is based on https://reviews.llvm.org/D125168 which adds a
wrapper to allow use of opaque pointers from the C API.
I added an opaque pointer mode test to echo.ll, and to fix assertions
that forbid the use of mixed typed and opaque pointers that were
triggering in it I had to also add wrappers for setOpaquePointers()
and isOpaquePointer().
I also changed echo.ll to remove a bitcast i32* %x to i8*, because
passing it through llvm-as and llvm-dis was generating a
%0 = bitcast ptr %x to ptr, but when building that same bitcast in
echo.cpp it was getting elided by IRBuilderBase::CreateCast
(https://github.com/llvm/llvm-project/blob/08ac66124874d70dab63c731da0244f9e29ef168/llvm/include/llvm/IR/IRBuilder.h#L1998-L1999).

Based on the output of include-what-you-use.
This is a big chunk of changes. It is very likely to break downstream code
unless they took a lot of care in avoiding hidden ehader dependencies, something
the LLVM codebase doesn't do that well :-/
I've tried to summarize the biggest change below:
- llvm/include/llvm-c/Core.h: no longer includes llvm-c/ErrorHandling.h
- llvm/IR/DIBuilder.h no longer includes llvm/IR/DebugInfo.h
- llvm/IR/IRBuilder.h no longer includes llvm/IR/IntrinsicInst.h
- llvm/IR/LLVMRemarkStreamer.h no longer includes llvm/Support/ToolOutputFile.h
- llvm/IR/LegacyPassManager.h no longer include llvm/Pass.h
- llvm/IR/Type.h no longer includes llvm/ADT/SmallPtrSet.h
- llvm/IR/PassManager.h no longer includes llvm/Pass.h nor llvm/Support/Debug.h
And the usual count of preprocessed lines:
$ clang++ -E -Iinclude -I../llvm/include ../llvm/lib/IR/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l

This is a followup to D103422. The DenseMapInfo implementations for
ArrayRef and StringRef are moved into the ArrayRef.h and StringRef.h

This required adding a few additional includes, as many files were

struct by name requires a Module. The method on Module merely accesses the LLVMContextImpl and no data from the module itself, so this patch moves getTypeByName to a static method on StructType that takes a Context and a name.

This adds support for scalable vector types in the C API and in
llvm-c-test, and also adds a test to ensure that llvm-c-test can properly
roundtrip operations involving scalable vectors.
While creating this diff, I discovered that the C API cannot properly roundtrip
_constant expressions_ involving shufflevector / scalable vectors, but that
seems to be a separate enough issue that I plan to address it in a future diff
(unless reviewers feel it should be addressed here).

This commit fixes a regression (from LLVM 10 to LLVM 11 RC3) in the LLVM
C API.
Previously, commit 1ee6ec2bf removed the mask operand from the
ShuffleVector instruction, storing the mask data separately in the
instruction instead; this reduced the number of operands of
ShuffleVector from 3 to 2. AFAICT, this change unintentionally caused
a regression in the LLVM C API. Specifically, it is no longer possible
to get the mask of a ShuffleVector instruction through the C API. This
patch introduces new functions which together allow a C API user to get
the mask of a ShuffleVector instruction, restoring the functionality
which was previously available through LLVMGetOperand().
This patch also adds tests for this change to the llvm-c-test
executable, which involved adding support for InsertElement,
ExtractElement, and ShuffleVector itself (as well as constant vectors)
to echo.cpp. Previously, vector operations weren't tested at all in
echo.ll.
I also fixed some typos in comments and help-text nearby these changes,
which I happened to spot while developing this patch. Since the typo
fixes are technically unrelated other than being in the same files, I'm
happy to take them out if you'd rather they not be included in the patch.

Summary:
The BFloat IR type is introduced to provide support for, initially, the BFloat16
datatype introduced with the Armv8.6 architecture (optional from Armv8.2
onwards). It has an 8-bit exponent and a 7-bit mantissa and behaves like an IEEE
754 floating point IR type.
This is part of a patch series upstreaming Armv8.6 features. Subsequent patches
will upstream intrinsics support and C-lang support for BFloat.

In order for dsymutil to collect .apinotes files (which capture
attributes such as nullability, Swift import names, and availability),
I want to propose adding an apinotes: field to DIModule that gets
translated into a DW_AT_LLVM_apinotes (path) nested inside
DW_TAG_module. This will be primarily used by LLDB to indirectly
extract the Swift names of Clang declarations that were deserialized
from DWARF.

This is part of PR44213 https://bugs.llvm.org/show_bug.cgi?id=44213
When importing (system) Clang modules, LLDB needs to know which SDK
(e.g., MacOSX, iPhoneSimulator, ...) they came from. While the sysroot
attribute contains the absolute path to the SDK, this doesn't work
well when the debugger is run on a different machine than the
compiler, and the SDKs are installed in different directories. It thus
makes sense to just store the name of the SDK instead of the absolute
path, so it can be found relative to LLDB.

[this re-applies c0176916a4824812d25a5a22c4ff7c95857b0cd6
with the correct commit message and phabricator link]
This addresses point 1 of PR44213.
https://bugs.llvm.org/show_bug.cgi?id=44213
The DW_AT_LLVM_sysroot attribute is used for Clang module debug info,
to allow LLDB to import a Clang module from source. Currently it is
part of each DW_TAG_module, however, it is the same for all modules in
a compile unit. It is more efficient and less ambiguous to store it
once in the DW_TAG_compile_unit.
This should have no effect on DWARF consumers other than LLDB.

I accidentally landed this patch with the wrong commit message ...
|
|
This is a purely cosmetic change that is NFC in terms of the binary
output. I bugs me that I called the attribute DW_AT_LLVM_isysroot
since the "i" is an artifact of GCC command line option syntax
(-isysroot is in the category of -i options) and doesn't carry any
useful information otherwise.
This attribute only appears in Clang module debug info.
