Fangrui Song ee957e045f [Driver] Allow -gsplit-dwarf on ELF OSes other than Linux and Fuchsia
In gcc, -gsplit-dwarf is handled in gcc/gcc.c as a spec
(ASM_FINAL_SPEC): objcopy --extract-dwo + objcopy --strip-dwo. In
gcc/opts.c, -gsplit_dwarf has the same semantic of a -g. Except for the
availability of the external command 'objcopy', nothing precludes the
feature working on other ELF OSes. llvm doesn't use objcopy, so it doesn't
have to exclude other OSes.

Jessica Paquette 55d495475c Make -mno-outline pass -enable-machine-outliner=never to ld in LTO
Since AArch64 has default outlining behaviour, we need to make sure that
-mno-outline is actually passed along to the linker in this case. Otherwise,
it will run by default on minsize functions even when -mno-outline is specified.

Also fix the darwin-ld test for this, which wasn't actually doing anything.

Roger Ferrer Ibanez e41a74e8d2 [RISCV] Pass -target-abi to -cc1as
The RISC-V assembler needs the target ABI because it defines a flag of the ELF
file, as described in [1].

Make clang (the driver) to pass the target ABI to -cc1as in exactly the same
way it does for -cc1.

Currently -cc1as knows about -target-abi but is not handling it. Handle it and
pass it to the MC layer via MCTargetOptions.

Sam Clegg 4dcf3acce6 [WebAssembly] Don't use default GetLinkerPath
We can't (don't want to) honor the same set of "-fuse-ld" flags with
WebAssembly since the ELF linkers (ld.lld, ld.gnu, etc) don't work with
wasm object files.

Instead we implement our own linker finding logic, similar or other
non-ELF platforms like MSVC.

We've had a few issues with CLANG_DEFAULT_LINKER overriding the
WebAssembly linker which doesn't make sense since there is no generic
linker that can handle WebAssembly today.

Craig Topper 3205dbb3f1 [Driver] Pass -malign-double from the driver to the cc1 command line
-malign-double is currently only implemented in the -cc1 interface. But its declared in Options.td so it is a driver option too. But you try to use it with the driver you'll get a message about the option being unused.

This patch teaches the driver to pass the option through to cc1 so it won't be unused. The Options.td says the option is x86 only but I didn't see any x86 specific code in its impementation in cc1 so not sure if the documentation is wrong or if I should only pass this option through the driver on x86 targets.

This reworked version of the feature no longer modifies today's default

can specify -DCLANG_DEFAULT_UNWINDLIB=libunwind when configuring
the compiler.

This should address the issues from the previous version.

Petr Hosek 28302c66d2 [runtimes] Move libunwind, libc++abi and libc++ to lib/ and include/
This change is a consequence of the discussion in "RFC: Place libs in
Clang-dedicated directories", specifically the suggestion that
libunwind, libc++abi and libc++ shouldn't be using Clang resource
directory.  Tools like clangd make this assumption, but this is
currently not true for the LLVM_ENABLE_PER_TARGET_RUNTIME_DIR build.
This change addresses that by moving the output of these libraries to
lib/<target> and include/ directories, leaving resource directory only
for compiler-rt runtimes and Clang builtin headers.

Yaxun Liu ab851939fc [HIP] Do not unbundle object files for -fno-gpu-rdc
When -fno-gpu-rdc is set, device code is compiled, linked, and assembled into fat binary
and embedded as string in object files. The object files are normal object files which
can be linked by host linker. In the linking stage, the object files should not be unbundled
when -fno-gpu-rdc is set since they are normal object files, not bundles. The object files
only need to be unbundled when -fgpu-rdc is set.

Currently clang always unbundles object files, disregarding -fgpu-rdc option.

This patch fixes that.

Thomas Lively f3b4f99007 [WebAssembly] Remove uses of ThreadModel
Summary:
In the clang UI, replaces -mthread-model posix with -matomics as the
source of truth on threading. In the backend, replaces
-thread-model=posix with the atomics target feature, which is now
collected on the WebAssemblyTargetMachine along with all other used
features. These collected features will also be used to emit the
target features section in the future.

The default configuration for the backend is thread-model=posix and no
atomics, which was previously an invalid configuration. This change
makes the default valid because the thread model is ignored.

A side effect of this change is that objects are never emitted with
passive segments. It will instead be up to the linker to decide
whether sections should be active or passive based on whether atomics
are used in the final link.
