Driver: hoist the `wchar_t` handling to the driver Move the logic for determining the `wchar_t` type information into the driver. Rather than passing the single bit of information of `-fshort-wchar` indicate to the frontend the desired type of `wchar_t` through a new `-cc1` option of `-fwchar-type` and indicate the signedness through `-f{,no-}signed-wchar`. This replicates the current logic which was spread throughout Basic into the `RenderCharacterOptions`. Most of the changes to the tests are to ensure that the frontend uses the correct type. Add a new test set under `test/Driver/wchar_t.c` to ensure that we calculate the proper types for the various cases. llvm-svn: 315126

There were some frustrating problems with the implementation of -Wwrite-strings. First and foremost, once the positive form of the flag was passed, it could never be disabled by passing -Wno-write-strings. Also, the diagnostic engine couldn't in turn use -Wwrite-strings to control diagnostics (as GCC does) because it was essentially hijacked to drive the language semantics. Fix this by giving CC1 a clean '-fconst-strings' flag to enable const-qualified strings in C and ObjC compilations. Corresponding '-fno-const-strings' is also added. Then the driver is taught to introduce '-fconst-strings' in the CC1 command when '-Wwrite-strings' dominates. This entire flag is basically GCC-bug-compatibility driven, so we also match GCC's bug where '-w' doesn't actually disable -Wwrite-strings. I'm open to changing this though as it seems insane. llvm-svn: 130051

Revert r194097: "With this patch -Wwrite-strings is still implemented with the terrible hack of passing -fconst-strings to -cc1" Passing or not a language option based on diagnostic settings is a bad idea, it breaks using a PCH that was compiled with different diagnostic settings. Also add a test case to make sure we don't regress. llvm-svn: 200964

Fix Clang's __DEPRECATED define to be controled by -Wdeprecated. This matches GCC behavior which libstdc++ uses to limit #warning-based messages about deprecation. The machinery involves threading this through a new '-fdeprecated-macro' flag for CC1. The flag defaults to "on", similarly to -Wdeprecated. We turn the flag off in the driver when the warning is turned off (modulo matching some GCC bugs). We record this as a language option, and key the preprocessor on the option when introducing the define. A separate flag rather than a '-D' flag allows us to properly represent the difference between C and C++ builds (only C++ receives the define), and it allows the specific behavior of following -Wdeprecated without potentially impacting the set of user-provided macro flags. llvm-svn: 130055

Add -ffp-contract = { fast | on | off } command line option support. This flag sets the 'fp-contract' mode, which controls the formation of fused floating point operations. Available modes are: - Fast: Form fused operations anywhere. - On: Form fused operations where allowed by FP_CONTRACT. This is the default mode. - Off: Don't form fused operations (in future this may be relaxed to forming fused operations where it can be proved that the result won't be affected). Currently clang doesn't support the FP_CONTRACT pragma, so the 'On' and 'Off' modes are equivalent. llvm-svn: 159794

Add a new flag, -fms-inline-asm, that enables the output of MS-style inline assembly. By default, we don't emit IR for MS-style inline assembly (see r158833 as to why). This is strictly for testing purposes and should not be enabled with the expectation that things will work. This is a temporary flag and will be removed once MS-style inline assembly is fully supported. llvm-svn: 160573

The only useful loop unrolling flag to give realistically is '-fno-unroll-loops'. The option to the backend is even called 'DisableUnrollLoops'. This is precisely the form that Clang *didn't* support. We didn't recognize the flag, we didn't pass it to the CC1 layer, and even if we did we wouldn't use it. Clang only inspected the positive form of the flag, and only did so to enable loop unrolling when the optimization level wasn't high enough. This only occurs for an optimization level that even has a chance of running the loop unroller when optimizing for size. This commit wires up the 'no' variant, and switches the code to actually follow the standard flag pattern of using the last flag and allowing a flag in either direction to override the default. I think this is still wrong. I don't know why we disable the loop unroller entirely *from Clang* when optimizing for size, as the loop unrolling pass *already has special logic* for the case where the function is attributed as optimized for size! We should really be trusting that. Maybe in a follow-up patch, I don't really want to change behavior here. llvm-svn: 187969

Add -freroll-loops to enable loop rerolling This adds -freroll-loops (and -fno-reroll-loops in the usual way) to enable loop rerolling as part of the optimization pass manager. This transformation can enable vectorization, reduce code size (or both). Briefly, loop rerolling can transform a loop like this: for (int i = 0; i < 3200; i += 5) { a[i] += alpha * b[i]; a[i + 1] += alpha * b[i + 1]; a[i + 2] += alpha * b[i + 2]; a[i + 3] += alpha * b[i + 3]; a[i + 4] += alpha * b[i + 4]; } into this: for (int i = 0; i < 3200; ++i) { a[i] += alpha * b[i]; } Loop rerolling is currently disabled by default at all optimization levels. llvm-svn: 194967

Add -fprofile-dir= to clang. -fprofile-dir=path allows the user to specify where .gcda files should be emitted when the program is run. In particular, this is the first flag that causes the .gcno and .o files to have different paths, LLVM is extended to support this. -fprofile-dir= does not change the file name in the .gcno (and thus where lcov looks for the source) but it does change the name in the .gcda (and thus where the runtime library writes the .gcda file). It's different from a GCOV_PREFIX because a user can observe that the GCOV_PREFIX_STRIP will strip paths off of -fprofile-dir= but not off of a supplied GCOV_PREFIX. To implement this we split -coverage-file into -coverage-data-file and -coverage-notes-file to specify the two different names. The !llvm.gcov metadata node grows from a 2-element form {string coverage-file, node dbg.cu} to 3-elements, {string coverage-notes-file, string coverage-data-file, node dbg.cu}. In the 3-element form, the file name is already "mangled" with .gcno/.gcda suffixes, while the 2-element form left that to the middle end pass. llvm-svn: 280306

Add GCC-compatible flags -fprofile-generate and -fprofile-use. This patch adds support for specifying where the profile is emitted in a way similar to GCC. These flags are used to specify directories instead of filenames. When -fprofile-generate=DIR is used, the compiler will generate code to write to <DIR>/default.profraw. The patch also adds a couple of extensions: LLVM_PROFILE_FILE can still be used to override the directory and file name to use and -fprofile-use accepts both directories and filenames. To simplify the set of flags used in the backend, all the flags get canonicalized to -fprofile-instr-{generate,use} when passed to the backend. The decision to use a default name for the profile is done in the driver. llvm-svn: 241825

[PGO] Change profile use cc1 option to handle IR level profiles This patch changes cc1 option for PGO profile use from -fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>. -fprofile-instr-use=<path> is now a driver only option. In addition to decouple the cc1 option from the driver level option, this patch also enables IR level profile use. cc1 option handling now reads the profile header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM} -- this is a common enum for -fprofile-instrument={}, for the profile instrumentation), and invoke the pipeline to enable the respective PGO use pass.

Move logic to enable the vectorizer to clang We used to decide whether to really vectorize depending on the optimization level in PassManagerBuilder. This patch moves this decision to the clang driver. We look at the optimization level and whether the f(no-)vectorize is set and decide whether to vectorize. This allows us to simplify the logic in PassManagerBuilder to just a check for whether the vectorizer should run or not. We now do the right thing for: $ clang -O1 -fvectorize $ clang -fno-vectorize -O3 llvm-svn: 188280

Driver must return non-zero code on errors in command line This is recommit of r302775, reverted in r302777 due to a fail in clang-tidy. Original mesage is below. Now if clang driver is given wrong arguments, in some cases it continues execution and returns zero code. This change fixes this behavior. The fix revealed some errors in clang test set. File test/Driver/gfortran.f90 added in r118203 checks forwarding gfortran flags to GCC. Now driver reports error on this file, because the option -working-directory implemented in clang differs from the option with the same name implemented in gfortran, in clang the option requires argument, in gfortran does not. In the file test/Driver/arm-darwin-builtin.c clang is called with options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed 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.

Teach Clang to recognize and ignore GCC's -fdiagnostics-show-location flag. We should probably wire at least some variants of this up to our actual diagnostics engine, but I'm leaving that for someone else.

Teach Clang to accept and ignore -f[no-]implicit-templates. This GCC flag is useful when you want to control whether implicit template instantiation occurs at the commandline level. Clang doesn't currently support such controls, but technically *always* implicitly instantiating (what Clang does, and what every other compiler still in use does by default) is valid behavior even under -fno-implicit-templates, it just may be slow and very wasteful. If people really want this, we can try to implement it, but I don't have an actual use. This should help fix the build of libstdc++ with Clang, its build system uses this flag. llvm-svn: 193319

[PM] Introduce options to enable the (still experimental) new pass manager, and a code path to use it. The option is actually a top-level option but does contain 'experimental' in the name. This is the compromise suggested by Richard in discussions. We expect this option will be around long enough and have enough users towards the end that it merits not being relegated to CC1, but it still needs to be clear that this option will go away at some point. The backend code is a fresh codepath dedicated to handling the flow with the new pass manager. This was also Richard's suggested code structuring to essentially leave a clean path for development rather than carrying complexity or idiosyncracies of how we do things just to share code with the parts of this in common with the legacy pass manager. And it turns out, not much is really in common even though we use the legacy pass manager for codegen at this point. I've switched a couple of tests to run with the new pass manager, and they appear to work. There are still plenty of bugs that need squashing (just with basic experiments I've found two already!) but they aren't in this code, and the whole point is to expose the necessary hooks to start experimenting with the pass manager in more realistic scenarios. That said, I want to *strongly caution* anyone itching to play with this: it is still *very shaky*. Several large components have not yet been shaken down. For example I have bugs in both the always inliner and inliner that I have already spotted and will be fixing independently. Still, this is a fun milestone. =D One thing not in this patch (but that might be very reasonable to add) is some level of support for raw textual pass pipelines such as what Sean had a patch for some time ago. I'm mostly interested in the more traditional flow of getting the IR out of Clang and then running it through opt, but I can see other use cases so someone may want to add it. And of course, *many* features are not yet supported! - O1 is currently more like O2 - None of the sanitizers are wired up - ObjC ARC optimizer isn't wired up - ... So plenty of stuff still lef to do! Differential Revision: https://reviews.llvm.org/D28077 llvm-svn: 290450

Add -f[no-]strict-return flag that can be used to avoid undefined behaviour in non-void functions that fall off at the end without returning a value when compiling C++. Clang uses the new compiler flag to determine when it should treat control flow paths that fall off the end of a non-void function as unreachable. If -fno-strict-return is on, the code generator emits the ureachable and trap IR only when the function returns either a record type with a non-trivial destructor or another non-trivially copyable type. The primary goal of this flag is to avoid treating falling off the end of a non-void function as undefined behaviour. The burden of undefined behaviour is placed on the caller instead: if the caller ignores the returned value then the undefined behaviour is avoided. This kind of behaviour is useful in several cases, e.g. when compiling C code in C++ mode. rdar://13102603 Differential Revision: https://reviews.llvm.org/D27163 llvm-svn: 290960

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. rdar://31581400 Differential Revision: https://reviews.llvm.org/D32081 llvm-svn: 300667

[Driver] Add option to manually control discarding value names in LLVM IR. Summary: Currently, assertion-disabled Clang builds emit value names when generating LLVM IR. This is controlled by the `NDEBUG` macro, and is not easily overridable. In order to get IR output containing names from a release build of Clang, the user must manually construct the CC1 invocation w/o the `-discard-value-names` option. This is less than ideal. For example, Godbolt uses a release build of Clang, and so when asked to emit LLVM IR the result lacks names, making it harder to read. Manually invoking CC1 on Compiler Explorer is not feasible. This patch adds the driver options `-fdiscard-value-names` and `-fno-discard-value-names` which allow the user to override the default behavior. If neither is specified, the old behavior remains.

[clang]: Add support for "-fno-delete-null-pointer-checks" Summary: Support for this option is needed for building Linux kernel. This is a very frequently requested feature by kernel developers. More details : https://lkml.org/lkml/2018/4/4/601 GCC option description for -fdelete-null-pointer-checks: This Assume that programs cannot safely dereference null pointers, and that no code or data element resides at address zero. -fno-delete-null-pointer-checks is the inverse of this implying that null pointer dereferencing is not undefined. This feature is implemented in as the function attribute "null-pointer-is-valid"="true". This CL only adds the attribute on the function. It also strips "nonnull" attributes from function arguments but keeps the related warnings unchanged. Corresponding LLVM change rL336613 already updated the optimizations to not treat null pointer dereferencing as undefined if the attribute is present.
