Re-commit r187637: "clang-cl: add more options" > This adds a bunch of options to clang-cl.

clang-cl: add the /c, /W0 and /W1 options This adds a few more clang-cl options. It also exposes two core clang options to the clang-cl mode: we need to be able to claim --driver_mode so it doesn't show up as unused in cl mode, and we need -### for tests.

clang-cl: Support the /fp options (PR23112) This hooks up the /fp options as aliases for -f[no-]fast-math and -f[no]-trapping-math.

Omit column info for CodeView by default Clang tracks only start columns, not start-end ranges. CodeView allows for that, but the VS debugger doesn't handle anything less than a complete range well--it either highlights the wrong part of a statement or truncates source lines in the assembly view. It's better to have no column information at all. So by default, we'll omit the column information for CodeView targeting Windows. Since the column info is still useful for sanitizers, I've promoted -gcolumn-info (and -gno-column-info) to a CoreOption and added a couple tests to make sure that works for clang-cl.

clang-cl: Remove -isystem, add -imsvc. r260990 exposed -isystem in clang-cl. -isystem adds a directory to the front of the system include search path. The idea was to use this to point to a hermetic msvc install, but as it turns out this doesn't work: -isystem then adds the hermetic headers in front of clang's builtin headers, and clang's headers that are supposed to wrap msvc headers (say, stdarg.h) aren't picked up at all anymore. So revert that, and instead expose -imsvc which works as if the passed directory was part of %INCLUDE%: The header is treated as a system header, but it is searched after clang's lib/Header headers.

[clang-cl] Handle -O correctly We had multiple bugs here: - We didn't support multiple optimization options in one argument. e.g. -O2y- - We didn't correctly expand -O[12dx] to their respective options. - We treated -O1 as clang -O1 instead of clang -Os. - We treated -Ox as clang -O3 instead of clang -O2. In fact, cl's -Ox option is *less* powerful than cl's -O2 option despite -Ox described as "Full Optimization". This fixes PR24003. llvm-svn: 243261

clang-cl: Accept MSVC 2015's `/source-charset:utf-8` flag. clang already treats all inputs as utf-8. Warn if anything but utf-8 is passed. Do this by mapping source-charset to finput-charset, which already behaves like this. Slightly tweak finput-charset to accept "utf-8" case-insensitively. This matches gcc's and cl.exe's behavior, and IANA says that character set names are case-insensitive. https://reviews.llvm.org/D23807 llvm-svn: 279531

clang-cl: Support MSVC2015's /validate-charset flag. Clang always assumes that files are utf-8. If an invalidly encoded character is used in an identifier, clang always errors. If it's used in a character literal, clang warns Winvalid-source-encoding (on by default). Clang never checks the encoding of things in comments (adding this seems like a nice feature if it doesn't impact performance). For cl.exe /utf-8 (which enables /validate-charset), if a bad character is used in an identifier, it emits both an error and a warning. If it's used in a literal or a comment, it emits a warning. So mapping /validate-charset to -Winvalid-source-encoding seems like a fairly decent fit. https://reviews.llvm.org/D23945 llvm-svn: 279872

Support -fno-delayed-template-parsing in clang-cl.exe Summary: This change adds support for the -fno-delayed-template-parsing option in clang-cl.exe. This allows developers using clang-cl.exe to opt out of emulation of MSVC's non-conformant template instantiation implementation while continuing to use clang-cl.exe for its emulation of cl.exe command-line options. The default behavior of clang-cl.exe (-fdelayed-template-parsing) is unchanged. The MSVC Standard Library implementation uses clang-cl.exe with this switch in its tests to ensure that the library headers work on compilers with the conformant two-phase-lookup behavior.

Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825

clang-cl: ignore compile-only options in link-only invocations. Previously we would warn about unused arguments such as /MD when linking. Clang already has logic to ignore compile-only options, e.g. for -D and -U. This patch extends that to include clang-cl's compile-only options too. Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825

clang-cl: Warn about /U flags that look like filenames (PR31662) Both on Mac and Windows, it's common to have a 'Users' directory in the root of the filesystem, so one might specify a filename as '/Users/me/myfile.c'. clang-cl (as well as MSVC's cl.exe) will interpret that as invoking the '/U' option, which is probably not what the user wanted. Add a warning about this. Differential Revision: https://reviews.llvm.org/D29198 llvm-svn: 293305
2017-01-28 01:09:41 +08:00

Driver: Handle /GR- in a compatible way with MSVC There are slight differences between /GR- and -fno-rtti which made mapping one to the other inappropriate. -fno-rtti disables dynamic_cast, typeid, and does not emit RTTI related information for the v-table. /GR- does not generate complete object locators and thus will not reference them in vftables. However, constructs like dynamic_cast and typeid are permitted. This should bring our implementation of RTTI up to semantic parity with MSVC modulo bugs. llvm-svn: 212138

Get default -fms-compatibility-version from cl.exe's version -fms-compatibility-version was defaulting to 18 (VS 2013), which is a pain if your environment is pointing to version 19 (VS 2015) libraries. If cl.exe can be found, this patch uses its version number as the default instead. It re-uses the existing code to find the Visual Studio binaries folder and WinAPI methods to check its version. You can still explicitly specify a compatibility version on the command line. If you don't have cl.exe, this should be a no-op and you'll get the old default of 18. This affected the tests, which assumed that if you didn't specific a version, that it would default to 18, but this won't be true for all machines. So a couple test cases had to be eliminated and a couple others had to be tweaked to allow for various outputs.

Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation.

[clang-cl] Add support for /Brepro The /Brepro flag controls whether or not the compiler should embed timestamps into the object file.

Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation.

// This test was super sneaky: "/Z7" means "line-tables", but "-gdwarf" occurs

// came out right, but had wrong semantics, because an invariant assumed by

// Args.hasArg to test whether a boolean flag is present without caring
// where it appeared. And for this test, it appeared to the left of -gdwarf
// which made it "win". This test could not detect that bug.

clang-cl: Expose -no-canonical-prefixes -no-canonical-prefixes is a weird flag: In gcc, it controls whether realpath() is called on the path of the driver binary. It's needed to support some usecases where gcc is symlinked to, see https://gcc.gnu.org/ml/gcc/2011-01/msg00429.html for some background. In clang, the resource dir is found relative to the compiler binary, and without -no-canonical-prefixes that's an absolute path. For clang, the main use case for -no-canonical-prefixes is to make the -resource-dir path added by the driver relative instead of absolute. Making it relative seems like the better default, but since neither clang not gcc have -canonical-prefixes without no- which makes changing the default tricky, and since some symlink behaviors do depend on the realpath() call at least for gcc, just expose -no-canonical-prefixes in clang-cl mode. Alternatively we could default to no-canonical-prefix-mode for clang-cl since it's less likely to be used in symlinked scenarios, but since you already need to about -no-canonical-prefixes for the non-clang-cl bits of your build, not hooking this of driver mode seems better to me. https://reviews.llvm.org/D47480 llvm-svn: 333761

clang-cl: Add "/clang:" pass-through arg support. The clang-cl driver disables access to command line options outside of the "Core" and "CLOption" sets of command line arguments. This filtering makes it impossible to pass arguments that are interpreted by the clang driver and not by either 'cc1' (the frontend) or one of the other tools invoked by the driver. An example driver-level flag is the '-fno-slp-vectorize' flag, which is processed by the driver in Clang::ConstructJob and used to set the cc1 flag "-vectorize-slp". There is no negative cc1 flag or -mllvm flag, so it is not currently possible to disable the SLP vectorizer from the clang-cl driver. This change introduces the "/clang:" argument that is available when the driver mode is set to CL compatibility. This option works similarly to the "-Xclang" option, except that the option values are processed by the clang driver rather than by 'cc1'. An example usage is: clang-cl /clang:-fno-slp-vectorize /O2 test.c Another example shows how "/clang:" can be used to pass a flag where there is a conflict between a clang-cl compat option and an overlapping clang driver option: clang-cl /MD /clang:-MD /clang:-MF /clang:test_dep_file.dep test.c In the previous example, the unprefixed /MD selects the DLL version of the msvc CRT, while the prefixed -MD flag and the -MF flags are used to create a make dependency file for included headers. One note about flag ordering: the /clang: flags are concatenated to the end of the argument list, so in cases where the last flag wins, the /clang: flags will be chosen regardless of their order relative to other flags on the driver command line.

clang-cl: ignore compile-only options in link-only invocations. Previously we would warn about unused arguments such as /MD when linking. Clang already has logic to ignore compile-only options, e.g. for -D and -U. This patch extends that to include clang-cl's compile-only options too. Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825
