LLD also supports order files using the `--symbol-ordering-file` option.
As the name would suggest, the order file format is slightly different
from gold; gold's order files specify section names, whereas LLD's
specify symbol names. Assuming you have an order file in the correct
format though, we should support using it with LLD.
Switch the check to actually use LLVM's linker detection rather than
just checking for the presence of the gold executable, since we might
have a gold executable present but be using LLD (or bfd for that matter)
as our linker.

Teach AsmParser to check with Assembler for when evaluating constant
expressions. This improves the handing of preprocessor expressions
that must be resolved at parse time. This idiom can be found as
assembling-time assertion checks in source-level assemblers. Note that
this relies on the MCStreamer to keep sufficient tabs on Section /
Fragment information which the MCAsmStreamer does not. As a result the
textual output may fail where the equivalent object generation would
pass. This can most easily be resolved by folding the MCAsmStreamer
and MCObjectStreamer together which is planned for in a separate
patch.
Currently, this feature is only enabled for assembly input, keeping IR
compilation consistent between assembly and object generation.

-cc1gen-reproducer driver option
The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped
Original message:
This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.
It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version

The new mode emits the information about the temporary files and Libclang-specific information

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

Restore the `-gz` option to the driver with some minor tweaks to handle
the additional case for `-Wa,--compress-debug-sections`.
This intends to make the compression of the debug information
controllable from the driver. The following is the behaviour:
-gz enable compression (ambiguous for format, will default to zlib-gnu)
-gz=none disable compression
-gz=zlib-gnu enable compression (deprecated GNU style zlib compression)
-gz=zlib enable compression (zlib based compression)
Although -Wa,-compress-debug-sections works, it should be discouraged
when using the driver to invoke the assembler. However, we permit the
assembler to accept the GNU as style argument --compress-debug-sections
to maintain compatibility.
Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally
specific -g for debug information to be generated.

These options control the behaviour of the compression of debug info
sections on ELF targets. Our behaviour slightly diverges from the
behaviour of GCC. `-gz` maps to the `-compress-debug-sections` rather
than `-compress-debug-sections=zlib` or
`-compress-debug-sections=zlib-gnu`. This small divergence allows us to
be compatible across versions of binutils (=zlib support was introduced
in 2.26, while earlier versions only support =zlib-gnu). This also
allows users to not have to worry about the version of the assembler
they may be using if they are not using the IAS. Previously, users
would have had to go through the internal option
`-compress-debug-sectionss` and pass that through to the assembler,
which is no longer needed.
llvm-svn: 305165
This is tied with the LLVM side of the change to expose the debug

One way to currently test the reproducers is to setup
"FORCE_CLANG_DIAGNOSTICS_CRASH=1" before invoking clang. This simulates
a crash and produces the same contents needed by the reproducers. The
reproducers are specially useful when triaging Modules issues, not only
on crashes, but also for reproducing misleading warnings, errors, etc.
Add a '-gen-reproducer' driver option to clang (or any similar name) and
give users a flag option.
Note that clang already has a -fno-crash-diagnostics, which disables the
crash reproducers. I've decided not to propose "-fcrash-diagnostics"

around a Linux kernel bug where the actual amount of available stack may be a
*lot* lower than the rlimit.
GCC also sets a higher stack rlimit on startup, but it goes all the way to
64MiB. We can increase this limit if it proves necessary.
The kernel bug is as follows: Linux kernels prior to version 4.1 may choose to
map the process's heap as little as 128MiB before the process's stack for a PIE
binary, even in a 64-bit virtual address space. This means that allocating more
than 128MiB before you reach the process's stack high water mark can lead to
crashes, even if you don't recurse particularly deeply.
We work around the kernel bug by touching a page deep within the stack (after
ensuring that we know how big it is), to preallocate virtual address space for
the stack so that the kernel doesn't allow the brk() area to wander into it,
when building clang as a Linux PIE binary.

LD64 does optimization on symbol layouts that gets disabled whenever an order file is passed (even if it is empty). This change prevents disabling that optimization, and still enables iterative generation and usage of order files.

Currently, clang-cl always uses Windows style for unquoting, and clang always
uses POSIX style for unquoting.
With this flag, it's possible to change these defaults.
In general, response file quoting should match the shell the response file is
used in. On Windows, it's possible to run clang-cl in a bash shell, or clang in
cmd.exe, so a flag for overriding the default behavior is natural there.
On non-Windows, Windows quoting probably never makes sense (except maybe in
Wine), but having clang-cl behave differently based on the host OS seems
strange too. So require that people who want to use posix-style response

logic to select an alternate target based on the executable it was
called as. For instance, if you symlink i686-linux-android-gcc to clang
and invoke it, the driver will act as though it were called with another
argument ("-target i686-linux-android"). This leads to visible effects
even in syntax-only compilations (like the ANDROID preprocessor symbol
being defined).
This behavior is not replicated for tool invocations--for instance,
clang::createInvocationFromCommandLine will not choose an alternate
target based on ArgList[0]. This means that configurations stored in
compilation databases aren't accurately replayed.
This patch separates the logic for selecting a mode flag and target from

a more suitable way.
This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.
