All but 2 of the vector builtins are only used by clang_builtin_alias.
When using clang_builtin_alias, the type string of the builtin is never
checked. Only the types in the function definition used for the alias
are checked.
This patch takes advantage of this to share a single builtin for
many different types. We already used type overloads on the IR intrinsic
so the codegen for the builtins that are being merge were already
the same. This extends the type overloading to the builtins.
I had to make a few tweaks to make this work.
-Floating point vector-vector vmerge now uses the vmerge intrinsic
instead of the vfmerge intrinsic. New isel patterns and tests are
added to support this.
-The SemaChecking for the immediate of vset_v/vget_v has been removed.
Determining the valid range is harder now. I've added masking to
ManualCodegen to ensure valid IR for invalid input.
This reduces the number of builtins from ~25000 to ~1100.

It isn't really pulling its weight and I think splitting it out from
-Wweak-vtables was the wrong call: I think it was just a bug in the
original warning, which was trying to not diagnose template
instantiations, implicit or explicit.
With the old approach we were updating `ObjCInterfaceType.Decl` to the
last encountered definition. But during loading modules
`ASTDeclReader::VisitObjCInterfaceDecl` keeps the *first* encountered
definition. So with multiple definitions imported there would be a
disagreement between expected definition in `ObjCInterfaceType.Decl` and
actual definition `ObjCInterfaceDecl::getDefinition` which can lead to
incorrect diagnostic.
Fix by not tracking definition in `ObjCInterfaceType` explicitly but by
getting it from redeclaration chain.
Partially reverted 919fc50034 keeping the
modified test case as the correct behavior is achieved in a different

Previously, btf_del_tag attribute supports record, field, global variable,
function and function parameter ([1], [2]). This patch added support for typedef.
The main reason is for typedef of an anonymous struct/union, we can only apply
btf_decl_tag attribute to the anonymous struct/union like below:
typedef struct { ... } __btf_decl_tag target_type
In this case, the __btf_decl_tag attribute applies to anonymous struct,
which increases downstream implementation complexity. But if
typedef with btf_decl_tag attribute is supported, we can have
typedef struct { ... } target_type __btf_decl_tag
which applies __btf_decl_tag to typedef "target_type" which make it
easier to directly associate btf_decl_tag with a named type.
This patch permitted btf_decl_tag with typedef types with this reason.

To reduce the number of explicit builds of a single module, we can try to squash multiple occurrences of the module with different command-lines (and context hashes) by removing benign command-line options. The greatest contributors to benign differences between command-lines are the header search paths.
In this patch, the lookup cache in `HeaderSearch` is used to identify paths that were actually used when implicitly building the module during scanning. This information is serialized into the unhashed control block of the implicitly-built PCM. The dependency scanner then loads this and may use it to prune the header search paths before computing the context hash of the module and generating the command-line.
We could also prune the header search paths when serializing `HeaderSearchOptions` into the PCM. That way, we could do it only once instead of every load of the PCM file by dependency scanner. However, that would result in a PCM file whose contents don't produce the same context hash as the original build, which is probably highly surprising.
There is an alternative approach to storing extra information into the PCM: wire up preprocessor callbacks to capture the used header search paths on-the-fly during preprocessing of modularized headers (similar to what we currently do for the main source file and textual headers). Right now, that's not compatible with the fact that we do an actual implicit build producing PCM files during dependency scanning. The second run of dependency scanner loads the PCM from the first run, skipping the preprocessing altogether, which would result in different results between runs. We can revisit this approach when we stop building implicitly during dependency scanning.
Depends on D102923.

Differential Revision: https://reviews.llvm.org/D102488
For dependency scanning, it would be useful to collect header search paths (provided on command-line via `-I` and friends) that were actually used during preprocessing. This patch adds that feature to `HeaderSearch` along with a new remark that reports such paths as they get used.
Previous version of this patch tried to use the existing `LookupFileCache` to report used paths via `HitIdx`. That doesn't work for `ComputeUserEntryUsage` (which is intended to be called *after* preprocessing), because it indexes used search paths by the file name. This means the values get overwritten when the code contains `#include_next`.
Note that `HeaderSearch` doesn't use `HeaderSearchOptions::UserEntries` directly. Instead, `InitHeaderSearch` pre-processes them (adds platform-specific paths, removes duplicates, removes paths that don't exist) and creates `DirectoryLookup` instances. This means we need a mechanism for translating between those two. It's not possible to go from `DirectoryLookup` back to the original `HeaderSearch`, so `InitHeaderSearch` now tracks the relationships explicitly.

ivar belongs to one module while its containing interface belongs to

The issue is with ObjCIvarDecl. IVar decl for IRGen is taken from
ObjCIvarRefExpr that is created in `Sema::BuildIvarRefExpr` using ivar
decl returned from `Sema::LookupIvarInObjCMethod`. And ivar lookup
returns a wrong decl because basically we take the first ObjCIvarDecl

wrong module comes first because `ASTReader::finishPendingActions`

Additionally, we can't rely on Clang's printing of function names via
the AST, so we just demangle the name instead.
