Anastasia Stulova dbb8d08637 [SPIR-V] Add linking using spirv-link.
Add support of linking files compiled into SPIR-V objects
using spirv-link.

Command line inteface examples:

clang --target=spirv64 test1.cl test2.cl

clang  --target=spirv64 test1.cl -o test1.o
clang  --target=spirv64 test1.o test2.cl -o test_app.out

This works independently from the SPIR-V generation method
(via an external tool or an internal backend) and applies
to either approach that is being used.

Egor Zhdan fda47db8ee [Clang][Sema] Fix attribute mismatch warning for ObjC class properties
If a class declares an instance property, and an inheritor class declares a class property with the same name, Clang Sema currently treats the latter as an overridden property, and compares the attributes of the two properties to check for a mismatch. The resulting diagnostics might be misleading, since neither of the properties actually overrides the another one.

Martin Storsjö 18b2385f2b [clang] [test] Fix clang-cl unused argument tests on paths that start with /U
This reinstates a test that was temporarily removed in
e26bbae302, in a form that works on
Darwin.

Use -LD instead of -link as a linker argument that is unused when
compiling, that produces warnings normally. -LD can be placed anywhere
in the command line, so that the command line ends with "-- %s", making
paths starting with /U correctly interpreted as paths, not options.

Martin Storsjö e26bbae302 [clang] [test] Remove newly added tests that fail on Darwin
These tests were recently added in

interpret the source path, %s, which begins with /Users, as a cl
option /U. Normally this is worked around by passing -- before
the arguments that must be interpreted as files, not options, but
in the current test, the -link option must be passed last, after any
file names.

Nikita Popov 2d1b55ebea [CodeGen] Make element type in emitArrayDestroy() predictable
When calling emitArrayDestroy(), the pointer will usually have
ConvertTypeForMem(EltType) as the element type, as one would expect.
However, globals with initializers sometimes don't use the same
types as values normally would, e.g. here the global uses
{ double, i32 } rather than %struct.T as element type.

Add an early cast to the global destruction path to avoid this
special case. The cast would happen lateron anyway, it only gets
moved to an earlier point.

Martin Storsjö 50ec1306d0 [clang] Add --start-no-unused-arguments/--end-no-unused-arguments to silence some unused argument warnings
When passing a set of flags to configure defaults for a specific
target (similar to the cmake settings `CLANG_DEFAULT_RTLIB`,
`CLANG_DEFAULT_UNWINDLIB`, `CLANG_DEFAULT_CXX_STDLIB` and
`CLANG_DEFAULT_LINKER`, but without hardcoding them in the binary),
some of the flags may cause warnings (e.g. `-stdlib=` when compiling C
code). Allow requesting selectively ignoring unused arguments among
some of the arguments on the command line, without needing to resort
to `-Qunused-arguments` or `-Wno-unused-command-line-argument`.

Fix up the existing diagnostics.c testcase. It was added in
response to PR12181 to fix handling of
`-Werror=unused-command-line-argument`, but the command line option
in the test (`-fzyzzybalubah`) now triggers "error: unknown argument"
instead of the intended warning. Change it into a linker input
(`-lfoo`) which triggers the intended diagnostic. Extend the
existing test case to check more cases and make sure that it keeps
testing the intended case.

Add testing of the new option to this existing test.

This does not apply to Android, which does not set errno in any math functions (https://cs.android.com/android/platform/superproject/+/master:bionic/libc/include/math.h;drc=master;l=59). The correct implementation for Android is to set -fno-math-errno by default, which was done in https://reviews.llvm.org/D51068. Therefore, this special exception is no longer needed for Android. Deleting it slightly reduces code complexity, clang executable size, compile time, and test time.

Nuno Lopes 7b1cb72ad9 [SROA] Switch replacement of dead/UB/unreachable ops from undef to poison
SROA has 3 data-structures where it stores sets of instructions that should
be deleted:
 - DeadUsers -> instructions that are UB or have no users
 - DeadOperands -> instructions that are UB or operands of useless phis
 - DeadInsts -> "dead" instructions, including loads of uninitialized memory
with users

The first 2 sets can be RAUW with poison instead of undef. No brainer as UB
can be replaced with poison, and for instructions with no users RAUW is a
NOP.

The 3rd case cannot be currently replaced with poison because the set mixes
the loads of uninit memory. I leave that alone for now.

Another case where we can use poison is in the construction of vectors from
multiple loads. The base vector for the first insertelement is now poison as
it doesn't matter as it is fully overwritten by inserts.

Collin Baker 7e08a12088 [clang] Fall back on Android triple w/o API level for runtimes search
Clang searches for runtimes (e.g. libclang_rt*) first in a
subdirectory named for the target triple (corresponding to
LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON), then if it's not found uses
.../lib/<os>/libclang_rt* with a suffix corresponding to the arch and
environment name.

Android triples optionally include an API level indicating the minimum
Android version to be run on
(e.g. aarch64-unknown-linux-android21). When compiler-rt is built with
LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=ON this API level is part of the
output path.

Linking code built for a later API level against a runtime built for
an earlier one is safe. In projects with several API level targets
this is desireable to avoid re-building the same runtimes many
times. This is difficult with the current runtime search method: if
the API levels don't exactly match Clang gives up on the per-target
runtime directory path.

To enable this more simply, this change tries target triple without
the API level before falling back on the old layout.

Another option would be to try every API level in the triple,
e.g. check aarch-64-unknown-linux-android21, then ...20, then ...19,
etc.

In the case of a function prototype that has a parameter type of an incomplete type it is impossible to get the size of the type. While such a function is not callable or able to be defined in the TU, it may still be mangled when generating debug info, which would previously lead to a crash.
This patch fixes that by simply bailing out of the loop and using the so far accumulated byte count. This matches GCCs behaviour as well: bc8d6c6013/gcc/config/i386/winnt.c (L203)
