  10. [CMake] Avoid passing -rtlib=compiler-rt when using compiler-rt

    We build libc++ and libc++abi with -nodefaultlibs, so -rtlib=compiler-rt
    has no effect and results in an 'argument unused during compilation'
    warning which breaks the build when using -Werror. We can therefore drop
    -rtlib=compiler-rt without any functional change; note that the actual
    compiler-rt linking is handled by HandleCompilerRT.

  12. [CMake][XRay] Silence llvm-config error when checking library support

    Otherwise this propagates all the way to CMake and results in an error
    during configuration. We check and handle the result and report warning
    separately so this is not changing the behavior.

  15. [libFuzzer] Make coverage.test work on ARM64

    This test instruments the following code with coverage, runs the fuzzer
    once, and asserts that there are uncovered PCs. The ARM64 backend
    optimizes this code using the `csel` (Conditional select) instruction,
    which removes all branching from the resulting machine code. The test
    then fails because we do not have any uncovered PCs. The easiest
    solution for now is to turn off optimization for the DSOs used in this

    int DSO1(int a) {
      if (a < 123456)
        return 0;
      return 1;

  16. [LoopReroll] Fix reroll root legality checking.

    The code checked that the first root was an appropriate distance from
    the base value, but skipped checking the other roots. This could lead to
    rerolling a loop that can't be legally rerolled (at least, not without
    rewriting the loop in a non-trivial way).

  23. DebugInfo: Split DWARF + gmlt + no-split-dwarf-inlining shouldn't emit anything to the .dwo file

    This configuration (due to r349207) was intended not to emit any DWO CU,
    but a degenerate CU was still being emitted - containing a header and a
    DW_TAG_compile_unit with no attributes.

    Under that situation, emit nothing to the .dwo file. (since this is a
    dynamic property of the input the .dwo file is still emitted, just with
    nothing in it (so a valid, but empty, ELF file) - if some other CU
    didn't satisfy this criteria, its DWO CU would still go there, etc) (detail/ViewSVN)

  25. Add fenv.h header

    Some implementations of fenv.h use macros to define the functions they provide. This can cause problems when `std::fegetround()` is spelled in source.

    This patch adds a `fenv.h` header to libc++ for the sole purpose of turning those macros into real functions.

  26. Be conservative about unordered accesses for the moment

    Background: As described in, I'm working towards separating volatile and atomic in the MMO uses for atomic instructions.

    In, I fixed a bug where isUnordered was returning the wrong result, but didn't account for the fact I was getting slightly ahead of myself. While both uses of isUnordered are correct (as far as I can tell), we don't have tests to demonstrate this and being aggressive gets in the way of having the removal of volatile truly be non-functional. Once D57601 lands, I will return to these call sites, revert this patch, and add the appropriate tests to show the expected behaviour.

  27. Add a new attribute, fortify_stdlib

    This attribute applies to declarations of C stdlib functions
    (sprintf, memcpy...) that have known fortified variants
    (__sprintf_chk, __memcpy_chk, ...). When applied, clang will emit
    calls to the fortified variant functions instead of calls to the

    In GCC, this is done by adding gnu_inline-style wrapper functions,
    but that doesn't work for us for variadic functions because we don't
    support __builtin_va_arg_pack (and have no intention to).

    This attribute takes two arguments, the first is 'type' argument
    passed through to __builtin_object_size, and the second is a flag
    argument that gets passed through to the variadic checking variants.

  28. [tblgen] Add a timer covering the time spent reading the Instruction defs

    This patch adds a -time-regions option to tablegen that can enable timers
    (currently only one) that assess the performance of tablegen itself. This
    can be useful for identifying scaling problems with tablegen backends.

    This particular timer has allowed me to ignore time that is not attributed
    the GISel combiner pass. It's useful by itself but it is particularly
    useful in combination with which causes
    this period of time to be annotated within Xcode Instruments which in turn
    allows profile samples and recorded allocations attributed to reading
    instructions to be filtered out. (detail/ViewSVN)

  29. [Sema] Mark GNU compound literal array init as an rvalue.

    Basically the same issue as string init, except it didn't really have
    any visible consequences before I removed the implicit lvalue-to-rvalue
    conversion from CodeGen.

    While I'm here, a couple minor drive-by cleanups: IgnoreParens never
    returns a ConstantExpr, and there was a potential crash with string init
    involving a ChooseExpr.

    The analyzer test change maybe indicates we could simplify the analyzer
    code a little with this fix?  Apparently a hack was added to support
    lvalues in initializers in r315750, but I'm not really familiar with the
    relevant code.

    Fixes regression reported in the kernel build at .

  30. [WebAssembly] Make thread-related options consistent

    There have been three options related to threads and users had to set
    all three of them separately to get the correct compilation results.
    This makes sure the relationship between the options makes sense and
    sets necessary options for users if only part of the necessary options
    are specified. This does:

    - Remove `-matomics`; this option alone does not enable anything, so
      removed it to not confuse users.
    - `-mthread-model posix` sets `-target-feature +atomics`
    - `-pthread` sets both `-target-feature +atomics` and
      `-mthread-model posix`
    Also errors out when explicitly given options don't match, such as
    `-pthread` is given with `-mthread-model single`.

    Except for custom floating point types x86_fp80 and ppc_fp128,

    Using bitwise operation can improve code size and performance.

  39. [X86] Correct the memory operand for the FLD emitted in FP_TO_INTHelper for 32-bit SSE targets.

    We were using DstTy, but that represents the integer type we are converting to which is i64 in this
    case. The FLD is part of an intermediate step to get from the SSE registers to the x87 registers.
    If the floating point type is f32, the memory operand should reflect a 4 byte access not an 8 byte
    access. The store we used to get from SSE to the stack is using the corect size.

    While there, consistenly use TheVT in place of Op.getOperand(0).getValueType() throughout the function. (detail/ViewSVN)

  41. [llvm-cxxfilt] Split and demangle stdin input

    Originally, llvm-cxxfilt would treat a line as a single mangled item to be demangled.
    If a mangled name appears in the middle of that string, that name would not be demangled.

    GNU c++filt  splits and demangles every word  in a  string that is piped to it via stdin.
    Prior to this patch llvm-cxxfilt would never split strings  piped to it.
    This patch replicates the GNU behavior and splits strings that are piped to it via stdin.

    This fixes PR39990
