The ABI parameter is used by a number of common backends, including ARM,
MIPS, PPC, and RISCV. Exposing it via the C API makes it possible for
users of those backends to configure the ABI without custom bindings.
This change adds support for accessing information about inline
assembly calls through the C API, enough to be able to round-trip the
information. This partially addresses https://llvm.org/pr42692 which
points out gaps in the C API
Getters for each of the parameters to LLVMGetInlineAsm/InlineAsm::get
have been added, such that the C API now has enough surface to clone
inline assembly calls
This API currently only returns the raw constraint string via
LLVMGetInlineAsmConstraintString: it may be prudent to also expose the
parsed constraints via InlineAsm::ParseConstraints, but I wasn't sure
how that should look like. This at least exposes the information for
clients

C bindings for the new pass manager seem to allow to set any option from LLVMPassBuilderOptions, except InlinerThreshold. Allow to configure it as well.

In code we use `#include "llvm/Lib/Header.h"` which is located in
"llvm/include/llvm/Lib/Header.h", so we use "llvm/include/" as a header
search path. We should put modulemaps in the same directory and
shouldn't rely on clang to search in immediate subdirectories.

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

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

The legacy PM uses in Polly have been removed, so recommit the patch.

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.

Adds a LLVMOrcCreateRTDyldObjectLinkingLayerWithMCJITMemoryManagerLikeCallbacks
function that can be used to create an RTDyldObjectLinkingLayer using callbacks
that are similar (but not identical) to those used in
LLVMCreateSimpleMCJITMemoryManager. This is intended to ease the transition to

The LLVM C bindings currently offer no way to query the version string
dynamically. This is a useful feature in situations where a program
isn't compiled against a specific version of LLVM but rather loads it
dynamically (e.g. using dlopen()).
In situations where the shared library filename doesn't reveal the
version (e.g. LLVM-C.dll) and to adapt to version-specific API
differences, it is then useful to be able to query the version string by
calling the proposed LLVMGetVersion function.
Differential Revision: https://reviews.llvm.org/D139381
These deprecated functions are incompatible with opaque pointers,
and have replacements that accept an explicit type. Drop them now
as a final warning to consumers of the C API to migrate their code
(while LLVMGetElementType still exists as a temporary workaround).
