Akira Hatanaka cae83f78aa [Sema] Issue diagnostics if a new/delete expression generates a call to
a c++17 aligned allocation/deallocation function that is unavailable in
the standard library on Apple platforms.

The aligned functions are implemented only in the following versions or
later versions of the OSes, so clang issues diagnostics if the deployment
target being targeted is older than these:

macosx: 10.13
ios: 11.0
tvos: 11.0
watchos: 4.0

The diagnostics are issued whenever the aligned functions are selected
except when the selected function has a definition in the same file.
If there is a user-defined function available somewhere else, option
-Wno-aligned-allocation-unavailable can be used to silence the
diagnostics.

Saleem Abdulrasool d064e91ece Revert "Revert r305164/5/7."
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.

Saleem Abdulrasool 7289ba9165 Driver: add support for `-gz` and `-gz=`
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.

Saleem Abdulrasool d3ba0ac2a5 Driver: pass along [-]-[no]compress-debug-sections unfiltered
Rather than validating the flags, pass them through without any
validation.  Arguments passed via -Wa or -Xassembler are passed directly
to the assembler without validation.  The validation was previously
required since we did not provide proper driver level support for
controlling the debug compression on ELF targets.  A subsequent change
will add support for the `-gz` and `-gz=` flags which provide proper
driver level control of the ELF compressed debug sections.

The baremetal test (r303873) has been added with expectance of very

account for even more systems, just use [[RESOURCE_DIR]] like a number

Vedant Kumar a125eb55cb [ubsan] Add a check for pointer overflow UB
Check pointer arithmetic for overflow.

For some more background on this check, see:

  https://wdtz.org/catching-pointer-overflow-bugs.html
  https://reviews.llvm.org/D20322

Patch by Will Dietz and John Regehr!

This version of the patch is different from the original in a few ways:

  - It introduces the EmitCheckedInBoundsGEP utility which inserts
    checks when the pointer overflow check is enabled.

  - It does some constant-folding to reduce instrumentation overhead.

  - It does not check some GEPs in CGExprCXX. I'm not sure that
    inserting checks here, or in CGClass, would catch many bugs.

Possible future directions for this check:

  - Introduce CGF.EmitCheckedStructGEP, to detect overflows when
    accessing structures.

Testing: Apart from the added lit test, I ran check-llvm and check-clang
with a stage2, ubsan-instrumented clang. Will and John have also done
extensive testing on numerous open source projects.

Linker script that is generated by the clang driver for creating fat binary puts target binaries for all offload targets into a single ELF section .omp_offloading. This is not convenient because it greatly complicates operations with the final fat binary once it is linked. For example extracting target binary for a particular target from such fat executable would not be an easy task if you have more than one offload target.

in r191435 and now clang reports error on this test.

File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.

Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.

Other revealed errors are mainly mistypes.

This feature is subtly broken when the linker is gold 2.26 or

When enabling any sanitizer, -fsanitize-use-after-scope is enabled by
default. This doesn't actually turn ASan on, because we've been getting

object/dwo file is produced then), yet the -fno-split-dwarf-inlining

effect...

So let it be specified & it'll be silently ignored if -gsplit-dwarf

combinations:

 * -x c -std=clN.M, which would previously effectively act as if -x cl were
   used, despite the input being a C source file. (-x cl -std=cNN continues
   to be disallowed.)

 * -x c++ -std=cuda, which would previously select C++98 + CUDA, despite that
   not being a C++ standard. (-x cuda -std=c++NN is still permitted, and
   selects CUDA with the given C++ standard as its base language.
   -x cuda -std=cuda is still supported with the meaning of CUDA + C++98.)

 * -x renderscript -std=c++NN, which would previously form a hybrid "C++ with
   RenderScript extensions" language. We could support such a thing, but

David Blaikie 8150355498 Move Split DWARF handling to an MC option/command line argument rather than using metadata
Since Split DWARF needs to name the actual .dwo file that is generated,
it can't be known at the time the llvm::Module is produced as it may be
merged with other Modules before the object is generated and that object
may be generated with any name.

By passing the Split DWARF file name when LLVM is producing object code
the .dwo file name in the object file can match correctly.

The support for Split DWARF for implicit modules remains the same -
using metadata to store the dwo name and dwo id so that potentially
multiple skeleton CUs referring to different dwo files can be generated
from one llvm::Module.

Alex Lorenz 1be800c511 Add support for editor placeholders to Clang
This commit teaches Clang to recognize editor placeholders that are produced
when an IDE like Xcode inserts a code-completion result that includes a
placeholder. Now when the lexer sees a placeholder token, it emits an
'editor placeholder in source file' error and creates an identifier token
that represents the placeholder. The parser/sema can now recognize the
placeholders and can suppress the diagnostics related to the placeholders. This
ensures that live issues in an IDE like Xcode won't get spurious diagnostics
related to placeholders.

This commit also adds a new compiler option named '-fallow-editor-placeholders'
that silences the 'editor placeholder in source file' error. This is useful
for an IDE like Xcode as we don't want to display those errors in live issues.

The driver needs to know whether it's building a module interface or

Bruno Cardoso Lopes 52dfe71645 [Driver] Add compiler option to generate a reproducer
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"
since it doesn't convey the ideia of reproduction despite a crash.

Kuba Mracek b26f857612 [asan] Turn -fsanitize-address-use-after-scope on by default [clang part]
AddressSanitizer has an optional compile-time flag, -fsanitize-address-use-after-scope, which enables detection of use-after-scope bugs. We'd like to have this feature on by default, because it is already very well tested, it's used in several projects already (LLVM automatically enables it when using -DLLVM_USE_SANITIZER=Address), it's low overhead and there are no known issues or incompatibilities.

This patch enables use-after-scope by default via the Clang driver, where we set true as the default value for AsanUseAfterScope. This also causes the lifetime markers to be generated whenever fsanitize=address is used. This has some nice consequences, e.g. we now have line numbers for all local variables.

The reason is that the -finclude-default-header flag is not meant to be on cc1 command other than the preprocessor.

Previously the driver would treat -m(i|tv|watch)os-simulator-version-min
as an alias of -m(i|tv|watch)os-version-min. This no longer works since
we now need to distinguish between the two options (the latter is used
for iOS running in a VM, for example).

This commit stops making the simulator options the aliases of the OS
options and defines a macro to differentiate between the two groups of
options.

Zachary Turner f630252349 Update clang-cl driver for MSVC 2017.
2017 changes the way you find an installed copy of
Visual Studio as well as its internal directory layout.
As a result, clang-cl was unable to find VS2017 even
when you had run vcvarsall to set up a toolchain
environment.  This patch updates everything for 2017
and cleans up the way we handle a tiered search a la
environment -> installation -> PATH for which copy
of Visual Studio to bind to.

Patch originally by Hamza Sood, with some fixups for landing.

John Brawn 5c4c61184a [Driver] Restructure handling of -ffast-math and similar options
The way -ffast-math and the various related options to tweak floating-point
handling are handled is inflexible and rather confusing. This patch restructures
things so that we go through the options adjusting our idea of what's enabled as
we go, instead of trying to figure each individual thing out by working
backwards from the end, as this makes the behaviour of each individual option
more clear.

Doing it this way also means we get gcc-compatible behaviour for when the
__FAST_MATH__ and __FINITE_MATH_ONLY__ macros are defined, as they should depend
on the final set of features that are enabled and not just on -ffast-math and
-ffinite-math-only specifically.

Summary:
This patch adds -f[no-]rtlib-add-rpath, which if enabled, embeds the
arch-specific subdirectory in resource directory using -rpath (instead
of doing so only during native compilation).

This patch also re-enables test arch-specific-libdir.c which was
silently unsupported because of the REQUIRES tag 'linux'.

Summary:

This change adds an arch-specific subdirectory in <ResourceDir>/lib/<OS>
to the linker search path.  This path also gets added as '-rpath' for
native compilation if a runtime is linked in as a shared object.  This
allows arch-specific libraries to be installed alongside clang.

Dave Bartolomeo 8ffce2ade3 Fix msc-version.c test to handle _MSC_VER=1910
Previously, VC++ has always set _MSC_VER to a four-digit value with the two least significant digits set to zero. Visual Studio 2017, however, sets _MSC_VER=1910, and we expect to update the least significant digit as we release major updates for VS 2017. This patch fixes the msc-version.c test to handle non-zero values in the two least significant digits of _MSC_VER.

The option -mexecute-only is translated into the backend option

the assembler does not recognize it. This patch stops clang from passing
this option to the assembler.
