While attempting to import libmdbx v0.9.2 (amalgmated source-code) into Zig, I hit the compile error:

./zig-cache/o/f8c145dcff9dc1971436ccf5076fab7f/cimport.zig:954:5: error: non-extern function is variadic
pub fn MDBX_MAP_RESIZED_is_deprecated(...) callconv(.C) c_int {
    ^

The following C code in mdbx.h:

/** MDBX_MAP_RESIZED
 * \ingroup c_err
 * \deprecated Please review your code to use MDBX_UNABLE_EXTEND_MAPSIZE
 * instead. */
MDBX_DEPRECATED static __inline int MDBX_MAP_RESIZED_is_deprecated() {
  return MDBX_UNABLE_EXTEND_MAPSIZE;
}
#define MDBX_MAP_RESIZED MDBX_MAP_RESIZED_is_deprecated()

... got translated to:

pub fn MDBX_MAP_RESIZED_is_deprecated(...) callconv(.C) c_int {
    return MDBX_UNABLE_EXTEND_MAPSIZE;
}

Does your zig include 50e8c38? I think this should have been fixed by that commit.

    stage2: improvements to `@setEvalBranchQuota`

     * extract magic number into a constant
     * properly use result location casting for the operand
     * naming convention for ZIR instructions

commit 638f93e
Author: g-w1 <jacoblevgw@gmail.com>
Date:   Sun Jan 3 15:45:22 2021 -0500

    stage2: implementation of `@setEvalBranchQuota`:

    `@setEvalBranchQuota` can be called before the comptime/inline call
    stack is created.

    For example:

    ```zig
    @setEvalBranchQuota(100);
    comptime {
        while (true) {}
    }
    ```

    Here we need to set the branch_quota before the comptime block creates a
    scope for the branch_count.

    stage2: Add support for testing LLVM enabled builds in test-stage2

    To make sure that we don't have to rebuild libc for every case, we now
    have a seperate cache directory for the global cache, which remains
    the same between test runs.

    Also make sure to destory the Compilation before executing a child process,
    otherwise the compiler deadlocks. (ziglang#7596)

    ```
    fn add(a: i32, b: i32) i32 {
        return a + b;
    }

    export fn main() c_int {
        var a: i32 = -5;
        const x = add(a, 7);
        var y = add(2, 0);

    stage2: comptime function calls and inline function calls

commit 6548322
Author: Andrew Kelley <andrew@ziglang.org>
Date:   Sat Jan 2 22:42:07 2021 -0700

    stage2: support recursive inline/comptime functions

    zir.Inst no longer has an `analyzed_inst` field. This is previously how
    we mapped ZIR to their TZIR counterparts, however with the way inline
    and comptime function calls work, we can potentially have the same ZIR
    structure being analyzed by multiple different analyses, such as during
    a recursive inline function call. This would cause the `analyzed_inst`
    field to become clobbered. So instead, we use a table to map the
    instructions to their semantically analyzed counterparts. This will help
    with multi-threaded compilation as well.

    Scope.Block.Inlining is split into 2 different layers of "sharedness".
    The first layer is shared by the whole inline/comptime function call
    stack. It contains the callsite where something is being inlined and the
    branch count/quota. The second layer is different per function call but
    shared by all the blocks within the function being inlined.

    Add support for debug dumping br and brvoid TZIR instructions.

    Remove the "unreachable code" error. It was happening even for this case:

    ```zig
    if (comptime_condition) return;
    bar(); // error: unreachable code
    ```

    We will need smarter logic for when it is legal to emit this compile
    error.

    Remove the ZIR test cases. These are redundant with other higher level
    Zig source tests we have, and maintaining support for ZIRModule as a
    first-class top level abstraction is getting in the way of clean
    compiler design for the main use case. We will have ZIR/TZIR based test
    cases someday to help with testing optimization passes and ZIR to TZIR
    analysis, but as is, these test cases are not accomplishing that, and
    they are getting in the way.

       caller rather than the callee.

Author: Andrew Kelley <andrew@ziglang.org>
Date:   Sat Jan 2 13:40:23 2021 -0700

    stage2: re-use ZIR for comptime and inline calls

    Instead of freeing ZIR after semantic analysis, we keep it around so
    that it can be used for comptime calls, inline calls, and generic
    function calls. ZIR memory is now managed by the Decl arena.

    Debug dump() functions are conditionally compiled; only available in
    Debug builds of the compiler.

    Add a test for an inline function call.

commit 9362f38
Author: Andrew Kelley <andrew@ziglang.org>
Date:   Sat Jan 2 12:32:30 2021 -0700

    stage2: implement function call inlining in the frontend

     * remove the -Ddump-zir thing. that's handled through --verbose-ir
     * rework Fn to have an is_inline flag without requiring any more memory
       on the heap per function.
     * implement a rough first version of dumping typed zir (tzir) which is
       a lot more helpful for debugging than what we had before. We don't
       have a way to parse it though.
     * keep track of whether the inline-ness of a function changes because
       if it does we have to go update callsites.
     * add compile error for inline and export used together.

    inline function calls and comptime function calls are implemented the
    same way. A block instruction is set up to capture the result, and then
    a scope is set up that has a flag for is_comptime and some state if the
    scope is being inlined.

    when analyzing `ret` instructions, zig looks for inlining state in the
    scope, and if found, treats `ret` as a `break` instruction instead, with
    the target block being the one set up at the inline callsite.

    Follow-up items:
     * Complete out the debug TZIR dumping code.
     * Don't redundantly generate ZIR for each inline/comptime function
       call. Instead we should add a new state enum tag to Fn.
     * comptime and inlining branch quotas.
     * Add more test cases.

Author: Andrew Kelley <andrew@ziglang.org>
Date:   Fri Jan 1 19:24:02 2021 -0700

    stage2: comptime function calls

     * Function calls that happen in a comptime scope get called at
       compile-time. We do this by putting the parameters in place as
       constant values and then running regular function analysis on the
       body.
     * Added `Scope.Block.dump()` for debugging purposes.
     * Fixed some code to call `identifierTokenString` rather than
       `tokenSlice`, making it work for `@""` syntax.
     * Implemented `Value.copy` for big integers.

    Follow-up issues to tackle:
     * Adding compile errors to the callsite instead of the callee Decl.
     * Proper error notes for "called from here".
       - Related: ziglang#7555
     * Branch quotas.
     * ZIR support?

    Pretty print Slices

    This code is adapted from pixelherodev paste from IRC

    I have added a new fmt option to handle printing slice values ``{v}`` or ``{V}``

    While i think it can be made the default, i want your opinion about it

    ```zig
        var slicea = [0]u32{};
        var sliceb = [3]u32{ 1, 2, 3 };

        std.log.info("Content: {v}", .{slicea});
        std.log.info("Content: {v}", .{sliceb});
    ```

    will print:

    ```
    info: Content: []
    info: Content: [1, 2, 3]
    ```

    Question:

    Should we drop ``{v}`` and make it the default behavior?

    Improve documentation for ArrayList, ArrayListUnmanaged, etc. (ziglang#7624)

    * Improve ArrayList & co documentation

    - Added doc comments about the validity of references to elements in
    an ArrayList and how they may become invalid after resizing operations.
    - This should help users avoid footguns in future.

    * Improve ArrayListUnmanaged & co's documentation

    - Port improved documentation from ArrayList and ArrayList aligned to
      their unmanaged counterparts.
    - Made documentation for ArrayListUnmanaged & co more inclusive and
      up-to-date.
    - Made documentation more consistent with `ArrayList`.

    * Corrections on ArrayList documentation.

    - Remove incorrect/unpreferred wording on ArrayList vs
      ArrayListUnmanaged.
    - Fix notes about the alignment of ArrayListAligned
    - Be more verbose with warnings on when pointers are invalidated.
    - Copy+paste a few warnings

    * add warning to replaceRange

    * revert changes to append documentation

    zig cc: detect framework include paths when native

commit 763d807

    Duplicate OSAtomic.h between aarch64 and x86_64

    The reason this is required is for two reasons: 1) the libc
    targeting `aarch64` macOS is slightly newer than that targeting
    `x86_64`, and 2) `OSAtomic.h` uses relative imports rather than
    system-wide imports for accompanying headers which clearly is an
    oversight on Apple's part. Until such time when `libkern` headers
    between `x86_64` and `aarch64` are identical, this will require a
    manual intervention to duplicate the relevant headers between the
    respective architectures.

    Detect native iframework dirs on macOS

    This commit adds default search paths for system frameworks
    on macOS while also adding `-isysroot` for OS versions at least BigSur.
    Since BigSur (11.0.1), neither headers nor libs exist in standard
    root locations (`/usr/include`, `/System/Library/Frameworks`). Instead, they
    are now exclusively part of the installed developer toolchain (either
    via XCode.app or CLT), and specifying `-isysroot` allows us to keep
    using universal search paths such as `/System/Library/Frameworks` while
    only changing the include flag from `-iframework` to
    `-iframeworkwithsysroot`.

If a static function is defined with no argument list and no prototype
is given, it should be treated as a function that takes no arguments
rather than as a variadic function.
