* Add flag to enable native half typePirama Arumuga Nainar2015-05-141-1/+1
| | | | | | | | | | | | | | | | | | | Summary: r235215 enables support in LLVM for legalizing f16 type in the IR. AArch64 already had support for this. r235215 and some backend patches brought support for ARM, X86, X86-64, Mips and Mips64. This change exposes the LangOption 'NativeHalfType' in the command line, so the backend legalization can be used if desired. NativeHalfType is enabled for OpenCL (current behavior) or if '-fnative-half-type' is set.

* Break \# in a depfile the same way as gcc.Paul Robinson2015-05-131-22/+18
| | | | | | | | Backslash followed by # in a filename should have both characters escaped, if you do it the way GNU Make wants. GCC doesn't, so we do it the way GCC does rather than the way GNU Make wants. llvm-svn: 237304
* Make GNUInline consistent with whether we use traditional GNU inline semantics.Peter Collingbourne2015-05-132-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we were setting LangOptions::GNUInline (which controls whether we use traditional GNU inline semantics) if the language did not have the C99 feature flag set. The trouble with this is that C++ family languages also do not have that flag set, so we ended up setting this flag in C++ modes (and working around it in a few places downstream by also checking CPlusPlus). The fix is to check whether the C89 flag is set for the target language, rather than whether the C99 flag is cleared. This also lets us remove most CPlusPlus checks. We continue to test CPlusPlus when deciding whether to pre-define the __GNUC_GNU_INLINE__ macro for consistency with GCC. There is a change in semantics in two other places where we weren't checking both CPlusPlus and GNUInline (FunctionDecl::doesDeclarationForceExternallyVisibleDefinition and FunctionDecl::isInlineDefinitionExternallyVisible), but this change seems to put us back into line with GCC's semantics (test case: test/CodeGen/inline.c). While at it, forbid -fgnu89-inline in C++ modes, as GCC doesn't support it, it didn't have any effect before, and supporting it just makes things more complicated.

* Fix dependency file escaping.Paul Robinson2015-05-131-5/+57
| | | | | | | | | | | | | | When writing a dependency (.d) file, if space or # is immediately preceded by one or more backslashes, escape the backslashes as well as the space or # character. Otherwise leave backslash alone. This straddles the fence between BSD Make (which does no escaping at all, and does not support space or # in filespecs) and GNU Make (which does support escaping, but will fall back to the filespec as-written if the escaping doesn't match an existing file).

* Reapply "Frontend: Stop leaking when not -disable-free"Duncan P. N. Exon Smith2015-05-041-14/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit r236422, effectively reapplying r236419. ASan helped me diagnose the problem: the non-leaking logic would free the ASTConsumer before freeing Sema whenever `isCurrentASTFile()`, causing a use-after-free in `Sema::~Sema()`. This version unconditionally frees Sema and the ASTContext before freeing the ASTConsumer. Without the fix, these were either being freed before the ASTConsumer was freed or leaked after, but they were always spiritually released so this isn't really a functionality change. I ran all of check-clang with ASan locally this time, so I'm hoping there aren't any more problems lurking. Original commit message: Try again to plug a leak that's been around since at least r128011 after coming across the FIXME. Nico Weber tried something similar in r207065 but had to revert in r207070 due to a bot failure. The build failure isn't visible anymore so I'm not sure what went wrong. I'm doing this slightly differently -- when not -disable-free I'm still resetting the members (just not leaking them) -- so maybe it will work out this time? Tests pass locally, anyway. llvm-svn: 236424

* [modules] Add -fmodules-local-submodule-visibility flag.Richard Smith2015-05-011-0/+2
| | | | | | | | | | | | | | | This flag specifies that the normal visibility rules should be used even for local submodules (submodules of the currently-being-built module). Thus names will only be visible if a header / module that declares them has actually been included / imported, and not merely because a submodule that happened to be built earlier declared those names. This also removes the need to modularize bottom-up: textually-included headers will be included into every submodule that includes them, since their include guards will not leak between modules. So far, this only governs visibility of macros, not of declarations, so is not ready for real use yet. llvm-svn: 236350

* [modules] Stop trying to fake up a linear MacroDirective history.Richard Smith2015-04-292-66/+38
| | | | | | | | | | | | | | Modules builds fundamentally have a non-linear macro history. In the interest of better source fidelity, represent the macro definition information faithfully: we have a linear macro directive history within each module, and at any point we have a unique "latest" local macro directive and a collection of visible imported directives. This also removes the attendent complexity of attempting to create a correct MacroDirective history (which we got wrong in the general case). No functionality change intended. llvm-svn: 236176

* Support generating NMake/Jom-style depfiles.Paul Robinson2015-04-272-5/+25
| | | | | | | | | | | | | | | NMake is a Make-like builder that comes with Microsoft Visual Studio. Jom (https://wiki.qt.io/Jom) is an NMake-compatible build tool. Dependency files for NMake/Jom need to use double-quotes to wrap filespecs containing special characters, instead of the backslash escapes that GNU Make wants. Adds the -MV option, which specifies to use double-quotes as needed instead of backslash escapes when writing the dependency file.

This change also allows us to use a uniform mechanism for writing module macro records, independent of whether they are local or imported. llvm-svn: 235614
* Create a frontend flag to disable CUDA cross-target call checksEli Bendersky2015-04-151-0/+3
| | | | | | | | | | | | | | | For CUDA source, Sema checks that the targets of call expressions make sense (e.g. a host function can't call a device function). Adding a flag that lets us skip this check. Motivation: for source-to-source translation tools that have to accept code that's not strictly kosher CUDA but is still accepted by nvcc. The source-to-source translation tool can then fix the code and leave calls that are semantically valid for the actual compilation stage.

* uselistorder: -mllvm -preserve-bc-use-list-order => -emit-llvm-uselistsDuncan P. N. Exon Smith2015-04-151-0/+4
| | | | | | | | | | | | | | | Stop relying on `cl::opt` to pass along the driver's decision to preserve use-lists. Create a new `-cc1` option called `-emit-llvm-uselists` that does the right thing (when -emit-llvm-bc). Note that despite its generic name, it *doesn't* do the right thing when -emit-llvm (LLVM assembly) yet. I'll hook that up soon. This doesn't really change the behaviour of the driver. The default is still to preserve use-lists for `clang -emit-llvm` and `clang -save-temps`, and nothing else. But it stops relying on global state (and also is a nicer interface for hackers using `clang -cc1`). llvm-svn: 234962

| | | | | | | | | | | | | | | | | | | | | | | The driver currently accepts but ignores the -freciprocal-math flag. This patch passes the flag through and enables 'arcp' fast-math-flag generation in IR. Note that this change does not actually enable the optimization for any target. The reassociation optimization that this flag specifies was implemented by http://reviews.llvm.org/D6334 : http://llvm.org/viewvc/llvm-project?view=revision&revision=222510 Because the optimization is done in the backend rather than IR, the backend must be modified to understand instruction-level fast-math-flags or a new function-level attribute must be created. Also note that -freciprocal-math is independent of any target-specific usage of reciprocal estimate hardware instructions. That requires its own flag ('-mrecip'). https://llvm.org/bugs/show_bug.cgi?id=20912 llvm-svn: 234493

That could trigger a significant amount of unnecessary work (pulling in all base classes recursively, for a start) and was causing problems for the modules buildbot due to cyclic deserializations. We now deserialize these on demand. This creates a certain amount of duplication with the handling of CXXBaseSpecifiers; I'll look into reducing that next. llvm-svn: 233052

* C++14: Disable sized deallocation by default due to ABI breakageReid Kleckner2015-03-201-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no widely deployed standard libraries providing sized deallocation functions, so we have to punt and ask the user if they want us to use sized deallocation. In the future, when such libraries are deployed, we can teach the driver to detect them and enable this feature. N3536 claimed that a weak thunk from sized to unsized deallocation could be emitted to avoid breaking backwards compatibility with standard libraries not providing sized deallocation. However, this approach and other variations don't work in practice. With the weak function approach, the thunk has to have default visibility in order to ensure that it is overridden by other DSOs providing sized deallocation. Weak, default visibility symbols are particularly expensive on MachO, so John McCall was considering disabling this feature by default on Darwin. It also changes behavior ELF linking behavior, causing certain otherwise unreferenced object files from an archive to be pulled into the link. Our second approach was to use an extern_weak function declaration and do an inline conditional branch at the deletion call site. This doesn't work because extern_weak only works on MachO if you have some archive providing the default value of the extern_weak symbol. Arranging to provide such an archive has the same challenges as providing the symbol in the standard library. Not to mention that extern_weak doesn't really work on COFF.
