Summary:
Ensure the clang-format unit tests are themselves clang-formatted
Having areas of the llvm code which are clang-format clean, give us more areas to run new clang-format binaries on ensuring we haven't broken anything.
It seems to me we SHOULD have this clang-formatted at a minimum, otherwise how can we expect others to use clang-format if we "don't eat our own dogfood", also if the tests are dependent on the formatting of the code then that would also be bad!

Link to LLVMTestingSupport via target_link_libraries() instead of
clang_target_link_libraries(). The latter is ineffective if tests
are linked to libclang.so. This solution is consistent with what other
tests do.
The approach in D30000 assumes that the '/' returned by path::begin()
is the first element for absolute paths, but that's not true on
Windows.
Also, on Windows backslashes in include lines often end up escaped
so that there are two of them. Having backslashes in include lines
is undefined behavior in most cases and implementation-defined
behavior in C++20, but since clang treats it as normal repeated
path separators, the diagnostic should too.
Unbreaks -Wnonportable-include-path for absolute paths on Windows,
and unbreaks it on non-Windows in the case of absolute paths with
repeated directory separators.
This affects e.g. the `#include __FILE__` technique if the file
passed to clang has the wrong case for the drive letter. Before:
C:\src\llvm-project>bin\clang-cl.exe c:\src\llvm-project\test.cc
c:\\src\\llvm-project\\test.cc(4,10): warning: non-portable path to file
'"c\\srccllvm-projectctest.cc.'; specified path differs in case from
file name on disk [-Wnonportable-include-path]

Summary:
Per Windows SEH Spec, except _leave, all other early exits of a _try (goto/return/continue/break) are considered abnormal exits. In those cases, the first parameter passes to its _finally funclet should be TRUE to indicate an abnormal-termination.
One way to implement abnormal exits in _try is to invoke Windows runtime _local_unwind() (MSVC approach) that will invoke _dtor funclet where abnormal-termination flag is always TRUE when calling _finally. Obviously this approach is less optimal and is complicated to implement in Clang.
Clang today has a NormalCleanupDestSlot mechanism to dispatch multiple exits at the end of _try. Since _leave (or try-end fall-through) is always Indexed with 0 in that NormalCleanupDestSlot, this fix takes the advantage of that mechanism and just passes NormalCleanupDest ID as 1st Arg to _finally.

I added a limit to make sure that _ExtInt isn't exposed on systems that
haven't considered it in their ABI. The ext-int.cpp Sema test didn't
have a triple, so on non x86/x86_64 it would fail with this new error.
This patch adds said triple to make sure this passes.
Since the _ExtInt type got into the repo, we've discovered that the ABI
implications weren't completely understood. The other architectures are
going to be audited (see D79118), however downstream targets aren't
going to benefit from this audit.
This patch disables the _ExtInt type by default and makes the
target-info an opt-in. As it is audited, I'll re-enable these for all
of our default targets.
I'm currently auditing all of the calling convention implications of
_ExtInt for all platforms, so splitting them up into their own test will
make this a much easier task to organize.
After speaking with Craig Topper about some recent defects, he pointed
out that _ExtInts should be passed indirectly if larger than the largest
int register, and like ints when smaller than that. This patch
implements that.
Note that this changed the way vaargs worked quite a bit, but they still

covering the most widespread cases (e.g. [[self class] classmethod]).
This solution introduces a way to track types represented by Class
objects and work with that instead of direct AST matching.

include guards or #pragma once, we should suggest either #including or
importing that header, and not importing a module that happens to
textually include it.
In passing, improve the notes we attach to the corresponding
diagnostics: calling an entity that we couldn't see "previous" is
confusing.

Prior to this change, for a few compiler-rt libraries such as ubsan and
the profile library, Clang would embed "-defaultlib:path/to/rt-arch.lib"
into the .drective section of every object compiled with
-finstr-profile-generate or -fsanitize=ubsan as appropriate.
These paths assume that the link step will run from the same working
directory as the compile step. There is also evidence that sometimes the
paths become absolute, such as when clang is run from a different drive
letter from the current working directory. This is fragile, and I'd like
to get away from having paths embedded in the object if possible. Long
ago it was suggested that we use this for ASan, and apparently I felt
the same way back then:
https://reviews.llvm.org/D4428#56536
This is also consistent with how all other autolinking usage works for
PS4, Mac, and Windows: they all use basenames, not paths.
To keep things working for people using the standard GCC driver
workflow, the driver now adds the resource directory to the linker
library search path when it calls the linker. This is enough to make
check-ubsan pass, and seems like a generally good thing.
Users that invoke the linker directly (most clang-cl users) will have to
add clang's resource library directory to their linker search path in
their build system. I'm not sure where I can document this. Ideally I'd
also do it in the MSBuild files, but I can't figure out where they go.
I'd like to start with this for now.

This is primarily motivated by the desire to move from Python2 to
Python3. `PYTHON_EXECUTABLE` is ambiguous. This explicitly identifies
the python interpreter in use. Since the LLVM build seems to be able to
completed successfully with python3, use that across the build. The old
path aliases `PYTHON_EXECUTABLE` to be treated as Python3.
When passing a value of a struct/union type from secure to non-secure
state (that is returning from a CMSE entry function or passing an
argument to CMSE-non-secure call), there is a potential sensitive
information leak via the padding bits in the structure. It is not
possible in the general case to ensure those bits are cleared by using
Standard C/C++.
This patch makes the compiler emit code to clear such padding
bits. Since type information is lost in LLVM IR, the code generation
is done by Clang.
For each interesting record type, we build a bitmask, in which all the
bits, corresponding to user declared members, are set. Values of
record types are returned by coercing them to an integer. After the
coercion, the coerced value is masked (with bitwise AND) and then
returned by the function. In a similar manner, values of record types
are passed as arguments by coercing them to an array of integers, and
the coerced values themselves are masked.
For union types, we effectively clear only bits, which aren't part of
any member, since we don't know which is the currently active one.
The compiler will issue a warning, whenever a union is passed to
non-secure state.
Values of half-precision floating-point types are passed in the least
significant bits of a 32-bit register (GPR or FPR) with the most
significant bits unspecified. Since this is also a potential leak of
sensitive information, this patch also clears those unspecified bits.

This reverts commit f8990feb12.
Summary:
Currently we map function summaries to names (i.e. strings). We can
associate more summaries with different signatures to one name, this way
we support overloading. During a call event we check whether the
signature of the summary matches the signature of the callee and we
apply the summary only in that case.
In this patch we change this mapping to associate a summary to a
FunctionDecl. We do lookup operations when the summary map is
initialized. We lookup the given name and we match the signature of the
given summary against the lookup results. If the summary matches the
FunctionDecl (got from the lookup result) then we add that to the
summary map. During a call event we compare FunctionDecl pointers.
Advantages of this new refactor:
- Cleaner mapping and structure for the checker.
- Possibly way more efficient handling of call events.
- A summary is added only if that is relevant for the given TU.
- We can get the concrete FunctionDecl by the time when we create the
summary, this opens up possibilities of further sanity checks
regarding the summary cases and argument constraints.
- Opens up to future work when we'd like to store summaries from IR to a
FunctionDecl (or from the Attributor results of the given
FunctionDecl).
Note, we cannot support old C functions without prototypes.

When LIBCLANG_BUILD_STATIC=ON and LLVM_ENABLE_PIC=ON, PIC version of

then adds it to targets. But when add_clang_library() calls install, it
only checks if ${name} is in targets.
To work around this issue, loop through both ${name} and ${name}_static
and install both of them if they're in targets. This is still correct if
only shared or static library is built. In those cases, only ${name} is

When a category/extension doesn't repeat a type bound, corresponding
type parameter is substituted with `id` when used as a type argument. As
a result, in the added test case it was causing errors like
> type argument 'T' (aka 'id') does not satisfy the bound ('id<NSCopying>') of type parameter 'T'
We are already checking that type parameters should be consistent
everywhere (see `checkTypeParamListConsistency`) and update
`ObjCTypeParamDecl` to have correct underlying type. And when we use the
type parameter as a method return type or a method parameter type, it is
substituted to the bounded type. But when we use the type parameter as a
type argument, we check `ObjCTypeParamType` that wasn't updated and
remains `id`.
Fix by updating not only `ObjCTypeParamDecl` UnderlyingType but also
TypeForDecl as we use the underlying type to create a canonical type for
`ObjCTypeParamType` (see `ASTContext::getObjCTypeParamType`).
This is a different approach to fixing the issue. The previous one was
02c2ab3d88 which was reverted in
4c539e8da1. The problem with the previous
approach was that `ObjCTypeParamType::desugar` was returning underlying
type for `ObjCTypeParamDecl` without applying any protocols stored in

Currently clang fails to compile the following CUDA program in device compilation:
__host__ int foo(int x) {
return 1;
}
template<class T>
__device__ __host__ int foo(T x) {
return 2;
}
__device__ __host__ int bar() {
return foo(1);
}
__global__ void test(int *a) {
*a = bar();
}
This is due to foo is resolved to the __host__ foo instead of __device__ __host__ foo.
This seems to be a bug since __device__ __host__ foo is a viable callee for foo whereas
clang is unable to choose it.
This patch fixes that.

This intrinsic isn't overloaded so we should query with types.
Doing so causes the backend to miss the intrinsic and not codegen it.

Static analyzer has a mechanism of clearing redundant nodes when
analysis hits a certain threshold with a number of nodes in exploded
graph (default is 1000). It is similar to GC and aims removing nodes
not useful for analysis. Unfortunately nodes corresponding to array
subscript expressions (that actively participate in data propagation)
get removed during the cleanup. This might prevent the analyzer from
generating useful notes about where it thinks the data came from.
This fix is pretty much consistent with the way analysis works
already. Lvalue "interestingness" stands for the analyzer's
possibility of tracking values through them.

Time profiler emits relative timestamps for events (the number of
microseconds passed since the start of the current process).
This patch allows combining events from different processes while
preserving their relative timing by emitting a new attribute
"beginningOfTime". This attribute contains the system time that
corresponds to the zero timestamp of the time profiler.
This has at least two use cases:
- Build systems can use this to merge time traces from multiple compiler
invocations and generate statistics for the whole build. Tools like
ClangBuildAnalyzer could also leverage this feature.
- Compilers that use LLVM as their backend by invoking llc/opt in
a child process. If such a compiler supports generating time traces
of its own events, it could merge those events with LLVM-specific
events received from llc/opt, and produce a more complete time trace.

As a result of that any file ID created for an include inside the

To fix this issue we first record number of created FIDs for predefined

Another solution would be to just give predefined buffers a valid source

targets other than Linux, Clang now returns small structs in registers

Add clang options -maix-struct-return (to return structs in memory) and
-msvr4-struct-return (to return structs in registers) to be compatible
with gcc. These options are only for PPC32; reject them on PPC64 and
other targets. The options are like -fpcc-struct-return and
-freg-struct-return for X86_32, and use similar code.
To actually return a struct in registers, coerce it to an integer of the
same size. LLVM may optimize the code to remove unnecessary accesses to
memory, and will return i32 in r3 or i64 in r3:r4.
