[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. Differential Revision: https://reviews.llvm.org/D116503

[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. Differential Revision: https://reviews.llvm.org/D116503

Reland "[FPEnv][Clang][Driver] Disable constrained floating point on targets lacking support." We currently have strict floating point/constrained floating point enabled for all targets. Constrained SDAG nodes get converted to the regular ones before reaching the target layer. In theory this should be fine. However, the changes are exposed to users through multiple clang options already in use in the field, and the changes are _completely_ _untested_ on almost all of our targets. Bugs have already been found, like "https://bugs.llvm.org/show_bug.cgi?id=45274". This patch disables constrained floating point options in clang everywhere except X86 and SystemZ. A warning will be printed when this happens.

.. option:: -frecord-command-line, -fno-record-command-line, -frecord-gcc-switches
Implement -frecord-command-line (-frecord-gcc-switches) Implement options in clang to enable recording the driver command-line in an ELF section. Implement a new special named metadata, llvm.commandline, to support frontends embedding their command-line options in IR/ASM/ELF. This differs from the GCC implementation in some key ways: * In GCC there is only one command-line possible per compilation-unit, in LLVM it mirrors llvm.ident and multiple are allowed. * In GCC individual options are separated by NULL bytes, in LLVM entire command-lines are separated by NULL bytes. The advantage of the GCC approach is to clearly delineate options in the face of embedded spaces. The advantage of the LLVM approach is to support merging multiple command-lines unambiguously, while handling embedded spaces with escaping.

[clang][driver] Restore the original help text for `-I` The help text for `-I` was recently expanded in [1]. The expanded version focuses on explaining the semantics of `-I` in Clang. We are now in the process of adding support for `-I` in Flang and this new description is incompatible with the semantics of `-I` in Flang. This was brought up in this review: * https://reviews.llvm.org/D93453 This patch reverts the original change in Options.td. This way the help text for `-I` remains generic enough so that it applies to both Clang and Flang. The expanded description of `-I` from [1] is moved to the `DocBrief` field for `-I`. This field is prioritised over the help text when generating ClangCommandLineReference.rst, so the user facing documentation for Clang retains the expanded description: * https://clang.llvm.org/docs/ClangCommandLineReference.html `DocBrief` fields are currently not used in Flang. As requested in the reviews, the help text and the expanded description are slightly refined.

[Clang][OpenMP][NVPTX] Replace `libomptarget-nvptx-path` with `libomptarget-nvptx-bc-path` D94700 removed the static library so we no longer need to pass `-llibomptarget-nvptx` to `nvlink`. Since the bitcode library is the only device runtime for now, instead of emitting a warning when it is not found, an error should be raised.

Recommit #2 "[Driver] Default to -fno-common for all targets" After a first attempt to fix the test-suite failures, my first recommit caused the same failures again. I had updated CMakeList.txt files of tests that needed -fcommon, but it turns out that there are also Makefiles which are used by some bots, so I've updated these Makefiles now too.

[clang] Add support for optional flag -fnew-infallible to restrict exception propagation The declaration for the global new function in C++ is generated in the compiler front-end. When examining exception propagation, we found that this is the largest root throw site propagator requiring unwind code to be generated for callers up the stack. Allowing this to be handled immediately with termination stops upward propagation and leads to significantly less landing pads generated. This in turns leads to a performance and .text size win. With `-fnew-infallible` this annotates the declaration with `throw()` and `__attribute__((returns_nonnull))`. `throw()` allows the compiler to assume exceptions do not propagate out of new and eliminate it as a root throw site. Note that the definition of global new is user-replaceable so users should ensure that the one used follows these semantics. Measuring internally, we're seeing at 0.5% CPU win in one of our large internal FB workload. Measuring on clang self-build (cd0a1226b50081e86eb75a89d01e8782423971a0) we get: thinlto/ "dwarfehprepare.NumCleanupLandingPadsRemaining": 153494, "dwarfehprepare.NumNoUnwind": 26309, thinlto_newinfallible/ "dwarfehprepare.NumCleanupLandingPadsRemaining": 143660, "dwarfehprepare.NumNoUnwind": 28744, a 1-143660/153494 = 6.4% reduction in landing pads and a 28744/26309 = 9.3% increase in the number of nounwind functions.

[OpenMP][OpenACC] Implement `ompx_hold` map type modifier extension in Clang (1/2) This patch implements Clang support for an original OpenMP extension we have developed to support OpenACC: the `ompx_hold` map type modifier. The next patch in this series, D106510, implements OpenMP runtime support. Consider the following example: ``` #pragma omp target data map(ompx_hold, tofrom: x) // holds onto mapping of x { foo(); // might have map(delete: x) #pragma omp target map(present, alloc: x) // x is guaranteed to be present printf("%d\n", x); } ``` The `ompx_hold` map type modifier above specifies that the `target data` directive holds onto the mapping for `x` throughout the associated region regardless of any `target exit data` directives executed during the call to `foo`. Thus, the presence assertion for `x` at the enclosed `target` construct cannot fail. (As usual, the standard OpenMP reference count for `x` must also reach zero before the data is unmapped.) Justification for inclusion in Clang and LLVM's OpenMP runtime: * The `ompx_hold` modifier supports OpenACC functionality (structured reference count) that cannot be achieved in standard OpenMP, as of 5.1. * The runtime implementation for `ompx_hold` (next patch) will thus be used by Flang's OpenACC support. * The Clang implementation for `ompx_hold` (this patch) as well as the runtime implementation are required for the Clang OpenACC support being developed as part of the ECP Clacc project, which translates OpenACC to OpenMP at the directive AST level. These patches are the first step in upstreaming OpenACC functionality from Clacc. * The Clang implementation for `ompx_hold` is also used by the tests in the runtime implementation. That syntactic support makes the tests more readable than low-level runtime calls can. Moreover, upstream Flang and Clang do not yet support OpenACC syntax sufficiently for writing the tests. * More generally, the Clang implementation enables a clean separation of concerns between OpenACC and OpenMP development in LLVM. That is, LLVM's OpenMP developers can discuss, modify, and debug LLVM's extended OpenMP implementation and test suite without directly considering OpenACC's language and execution model, which can be handled by LLVM's OpenACC developers. * OpenMP users might find the `ompx_hold` modifier useful, as in the above example. See new documentation introduced by this patch in `openmp/docs` for more detail on the functionality of this extension and its relationship with OpenACC. For example, it explains how the runtime must support two reference counts, as specified by OpenACC. Clang recognizes `ompx_hold` unless `-fno-openmp-extensions`, a new command-line option introduced by this patch, is specified.

Set OpenMP version (e.g. 45 for OpenMP 4.5, 50 for OpenMP 5.0). Default value is 50.
[OpenMP][OpenACC] Implement `ompx_hold` map type modifier extension in Clang (1/2) This patch implements Clang support for an original OpenMP extension we have developed to support OpenACC: the `ompx_hold` map type modifier. The next patch in this series, D106510, implements OpenMP runtime support. Consider the following example: ``` #pragma omp target data map(ompx_hold, tofrom: x) // holds onto mapping of x { foo(); // might have map(delete: x) #pragma omp target map(present, alloc: x) // x is guaranteed to be present printf("%d\n", x); } ``` The `ompx_hold` map type modifier above specifies that the `target data` directive holds onto the mapping for `x` throughout the associated region regardless of any `target exit data` directives executed during the call to `foo`.

Enable stack protectors for some functions vulnerable to stack smashing. This uses a loose heuristic which considers functions vulnerable if they contain a char (or 8bit integer) array or constant sized calls to alloca , which are of greater size than ssp-buffer-size (default: 8 bytes). All variable sized calls to alloca are considered vulnerable. A function with a stack protector has a guard value added to the stack frame that is checked on function exit. The guard value must be positioned in the stack frame such that a buffer overflow from a vulnerable variable will overwrite the guard value before overwriting the function's return address. The reference stack guard value is stored in a global variable.

[X86] Add Indirect Thunk Support to X86 to mitigate Load Value Injection (LVI) This pass replaces each indirect call/jump with a direct call to a thunk that looks like: lfence jmpq *%r11 This ensures that if the value in register %r11 was loaded from memory, then the value in %r11 is (architecturally) correct prior to the jump. Also adds a new target feature to X86: +lvi-cfi ("cfi" meaning control-flow integrity) The feature can be added via clang CLI using -mlvi-cfi. This is an alternate implementation to https://reviews.llvm.org/D75934 That merges the thunk insertion functionality with the existing X86 retpoline code.

[Driver][CodeGen] Add -mprefer-vector-width driver option and attribute during CodeGen. This adds a new command line option -mprefer-vector-width to specify a preferred vector width for the vectorizers. Valid values are 'none' and unsigned integers. The driver will check that it meets those constraints. Specific supported integers will be managed by the targets in the backend. Clang will take the value and add it as a new function attribute during CodeGen. This represents the alternate direction proposed by Sanjay in this RFC: http://lists.llvm.org/pipermail/llvm-dev/2017-November/118734.html The syntax here matches gcc, though gcc treats it as an x86 specific command line argument. gcc only allows values of 128, 256, and 512. I'm not having clang check any values. Differential Revision: https://reviews.llvm.org/D40230 llvm-svn: 320419

[x86][seses] Add clang flag; Use lvi-cfi with seses This patch creates a clang flag to enable SESES. This flag also ensures that lvi-cfi is on when using seses via clang. SESES should use lvi-cfi to mitigate returns and indirect branches. The flag to enable the SESES functionality only without lvi-cfi is now -x86-seses-enable-without-lvi-cfi to warn users part of the mitigation is not enabled if they use this flag. This is useful in case folks want to see the cost of SESES separate from the LVI-CFI. Reviewed By: sconstab Differential Revision: https://reviews.llvm.org/D79910

[X86] Add CRC32 feature. d8faf03807ac implemented general-regs-only for X86 by disabling all features with vector instructions. But the CRC32 instruction in SSE4.2 ISA, which uses only GPRs, also becomes unavailable. This patch adds a CRC32 feature for this instruction and allows it to be used with general-regs-only.
