a24a1a411d Allow case-insensitive values for -mtune for AArch64 target in line with GCC.
GCC allows case-insensitive values for -mcpu, -march and -mtune options.
This patch implements the same behaviour for the -mtune option for the AArch64 target.

546a19628b Fix -save-temp when using objc-arc, sanitizer and profiling
Currently, -save-temp will cause ObjCARC optimization to be dropped,
sanitizer pass to run early in the pipeline, and profiling
instrumentation to run twice.
Fix the issue by properly disable all passes in the optimization
pipeline when generating bitcode output and parse some of the Language
Options even when the input is bitcode so the passes can be setup
correctly.

578caf5da7 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.

The patch is the same except for the addition of a new test for the
issue that required reverting the dependent llvm commit.

--Original Commit Message--

Pass down the -flto option to the -cc1 job, and from there into the
CodeGenOptions and onto the PassManagerBuilder. This enables gating
the new EliminateAvailableExternally module pass on whether we are
preparing for LTO.

If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not
included as we want to preserve available externally functions for possible

On Windows the user may invoke the linker directly, so we might not have an

instruct the code generator to embed linker directive in the object file
that cause the required runtime libraries to be linked.

We might also want to do something similar for ASan, but it seems to have
its own special complexities which may make this infeasible.

9535429270 Pedantically rename all Tool subclasses to be nouns, not verbs. NFC
Classes in Tools.h inherit ultimately from Tool, which is a noun,
but subclasses of Tool were named for their operation, such as "Compile",
wherein the constructor call "Compile(args...)" could be misconstrued
as actually causing a compile to happen.

Likewise various other methods were not harmonious with their effect,
in that "BuildLinker()" returned a "new namespace::Link(...)"
instead of a "new namespace::Linker(...)" which it now does.

Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names.
And there is no particulary great way to name the "Lipo-er" and a few others.

907880edd9 [CFI] Require -flto instead of implying it.
Summary:
This is unfortunate, but would let us land http://reviews.llvm.org/D10467,
that makes ToolChains responsible for computing the set of sanitizers
they support.

Unfortunately, Darwin ToolChains doesn't know about actual OS they
target until ToolChain::TranslateArgs() is called. In particular, it
means we won't be able to construct SanitizerArgs for these ToolChains
before that.

This change removes SanitizerArgs::needsLTO() method, so that now
ToolChain::IsUsingLTO(), which is called very early, doesn't need
SanitizerArgs to implement this method.

Docs and test cases are updated accordingly. See
https://llvm.org/bugs/show_bug.cgi?id=23539, which describes why we
start all these.

  to control safe stack usage (the safe stack is disabled by default).

- Add __attribute__((no_sanitize("safe-stack"))) attribute to clang that can be
  used to disable the safe stack for individual functions even when enabled
  globally.
