The validateOutputSize and validateInputSize need to check whether
AVX or AVX512 are enabled. But this can be affected by the
target attribute so we need to factor that in.
This patch moves some of the code from CodeGen to create an
appropriate feature map that we can pass to the function.

Commit d77ae1552f
("[DebugInfo] Support to emit debugInfo for extern variables")
added deebugInfo for extern variables for BPF target.
The commit is reverted by 891e25b02d
as the committed tests using %clang instead of %clang_cc1 causing
test failed in certain scenarios as reported by Reid Kleckner.
This patch fixed the tests by using %clang_cc1.

getLastArgIntValue is a useful utility function to get command line argument as an integer.
Currently it is in Frontend so that it can only be used by clang -cc1. Move it to basic so
that it can also be used by clang driver.

In the current implementation of clang the canonicalization of paths in
diagnostic messages (when using -fdiagnostics-absolute-paths) only works
if the symbolic link is in the directory part of the filename, not if
the file itself is a symbolic link to another file.
This patch adds support to canonicalize the complete path including the
file.

Summary:
This adds parsing of the qualifiers __ptr32, __ptr64, __sptr, and __uptr and
lowers them to the corresponding address space pointer for 32-bit and 64-bit pointers.
(32/64-bit pointers added in https://reviews.llvm.org/D69639)
A large part of this patch is making these pointers ignore the address space
when doing things like overloading and casting.

According to OpenMP 5.0, if clause can be used in for simd directive. If
condition in the if clause if false, the non-vectorized version of the
loop must be executed.
Extern variable usage in BPF is different from traditional
pure user space application. Recent discussion in linux bpf
mailing list has two use cases where debug info types are
required to use extern variables:
- extern types are required to have a suitable interface
in libbpf (bpf loader) to provide kernel config parameters
to bpf programs.
https://lore.kernel.org/bpf/CAEf4BzYCNo5GeVGMhp3fhysQ=_axAf=23PtwaZs-yAyafmXC9g@mail.gmail.com/T/#t
- extern types are required so kernel bpf verifier can
verify program which uses external functions more precisely.
This will make later link with actual external function no
need to reverify.

This patch added clang support to emit debuginfo for extern variables
with a TargetInfo hook to enable it. The debuginfo for the
extern variable is emitted only if that extern variable is
referenced in the current compilation unit.
Currently, only BPF target enables to generate debug info for
extern variables. The emission of such debuginfo is disabled for C++
at this moment since BPF only supports a subset of C language.
Emission with C++ can be enabled later if an appropriate use case
is identified.
-fstandalone-debug permits us to see more debuginfo with the cost
of bloated binary size. This patch did not add emission of extern
variable debug info with -fstandalone-debug. This can be
re-evaluated if there is a real need.

It was tempting to use RealFileSystem as the default, but that makes it

This is a follow-up to 590f279c45, which
moved some of the callers to use VFS.
It turned out more code in Driver calls into real filesystem APIs and

As part of an audit of whether all errors are being reported from the
ASTReader, delay err_module_file_conflict if a diagnostic is already in
flight when it is hit. This required plumbing an extra argument through
the delayed diagnostic mechanics in DiagnosticsEngine.
Summary:
When downstream LLVM distributions (like AOSP) set the CLANG_VENDOR
cmake variable, the version string printed by the clang driver looks
like:
$ clang --version
[CLANG_VENDOR] clang version X.X.X ([CLANG_REPOSITORY_STRING] sha) (based on LLVM X.X.X)
Rather than the more standard:
$ clang --version
clang version X.X.X ([CLANG_REPOSITORY_STRING] sha)
Based on feedback the the version string is a little long, the trailing
"(based on LLVM X.X.X)" is redundant and makes less sense after moving
LLVM to the monorepo. And it is only added should vendors set the cmake
variable CLANG_VENDOR. Let's remove it.

All SSE capable CPUs have MMX. 3dnow implicitly enables MMX.
We have code that detects if sse is enabled and implicitly enables
MMX unless -mno-mmx is passed. So in most cases we were already
enabling MMX if march passed a CPU that supported SSE.
The exception to this is if you pass -march for a cpu supports SSE
and also pass -mno-sse. We should still enable MMX since its part
of the CPU capability.
