Re-commit r187637: "clang-cl: add more options" > This adds a bunch of options to clang-cl. Notably, this includes > all the options that get passed when doing a default build of a > command-line project with msbuild.exe in Debug and Release modes, > and I believe all flags from Reid's original patch. The original commit was reverted in r187640 after it broke the Mac build. This should now be fixed, by Clang r187668, LLVM r187675, and putting a -- before %s in the test. llvm-svn: 187679

// Note: %s must be preceded by --, otherwise it may be interpreted as a
// command-line option, e.g. on Mac where %s is commonly under /Users.
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. It probably doesn't match cl.exe's behaviour completely (e.g. LLVM is currently never as precise as /fp:precise), but it's close enough.

[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: 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

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

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

// line-tables-only} appear. If you assume that, then you can safely use
// 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.
