    [AArch64] Modify read of threadpointer to be marked that it may load memory, rather than having unmodeled side effects.

commit 052ab4e90209797c6da67f78f71255a79e71f3c8
Author: TB Schardl <[email protected]>
Date:   Mon Oct 9 10:26:09 2023 +0000

    [AArch64] Mark the read of the threadpointer has having unmodeled side effects to prevent misoptimization in programs where the executing thread may change across a function call.

    In principle, this change could be made more precise to enable some
    optimizations of this operation, including removal of redundant reads
    when there is no intervening function call.  But it is not clear what
    attributes currently exist that could be attached to this operation to
    model its behavior more precisely.

    [TailRecursionElimination] Allow TRE to occur when a tail call is separated from a return by a sync and a tapir.runtime.end intrinsic.  In such cases, TRE removes the tapir.runtime intrinsics altogether.

commit b93ccc5bfb6c51905111c5bdac94c211328dda53
Author: TB Schardl <[email protected]>
Date:   Tue Feb 7 11:34:51 2023 +0000

    [TailRecursionElimination] Avoid performing tail-recursion elimination for a tail call followed by a sync if there exists a sync preceding that call in the function.  TRE in this case can change the synchronization of the program, by causing some spawns to sync earlier than before.  TRE in such cases appears to make parallel scalability worse.

    [TapirUtils] Two changes involving optimizations with taskframes:

    - When serializing a detach, if the task contains a sync, replace the
      detach with a taskframe, to prevent that sync from synchronizing
      tasks in the parent.

    - Allow a taskframe containing allocas to be replaced with
      stacksave/stackrestore intrinsics.

    [CodeGenFunction][CGCilk] Optimize emission of tapir_runtime_{start,end} intrinsics when nested _Cilk_scopes are used within a function.

commit feed355d73e532cdfb0615f223bb15a6c98f6b8a
Author: TB Schardl <[email protected]>

    [TapirToTarget][LoweringUtils] Add generic handling of tapir_runtime_{start,end} intrinsics to Tapir targets.

commit 007f01951350f123d20593510b076e1ec2d059c4
Author: TB Schardl <[email protected]>
Date:   Sat Jul 24 16:15:06 2021 +0000

    [clang/Cilk][Intrinsics] Add _Cilk_scope construct, a lexical scope
    that guarantees upon exit to _Cilk_sync any tasks spawned within the
    scope.  Add intrinsics to allow the _Cilk_scope construct to mark
    where a Tapir-target runtime may be started and stopped at the
    beginning and end of the scope, respectively.

    These intrinsics are meant only to be hints to a Tapir-target runtime,
    not definitive markers for where the runtime must be started or
    stopped.  This requirement is necessary to make it safe to nest
    _Cilk_scopes, either within the same function or indirectly
    via function calls.

    No particular compiler optimizations are included for these
    intrinsics, although some optimizations may be useful to add in the
    future.

    [TapirLoopInfo] When searching for a primary induction variable for a Tapir loop, select the widest induction-variable type only among the possible primary induction variables, i.e., integer IVs that start at 0 and have step value 1.  This change allows LoopSpawning to handle Tapir loops with multiple IVs where the primary IV is not necessarily the integer IV with the widest type.
