            Bug ID: 242220
           Summary: Remove the workaround for llvm.38289?
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: zhonghao at sjtu.edu.cn

I find a workaround for llvm38289:
https://github.com/WebKit/WebKit/blob/156d59fe06826ce27650093d1abfd566d9b667d4/Source/WTF/wtf/Int128.cpp
// Workaround for clang bug: https://bugs.llvm.org/show_bug.cgi?id=38289
// Casting from long double to uint64_t is miscompiled and drops bits.
// It is more work, so only use when we need the workaround.
static UInt128Impl MakeUInt128FromFloat(long double v) {...



The compiler bug is marked as fixed:https://bugs.llvm.org/show_bug.cgi?id=38289

Shall the workarounds be removed?
