            Bug ID: 43283
           Summary: Implement llvm.sponentry for x86
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org

Some languages perform manual stack checks to detect stack overflows and other
operations. Currently llvm.sponentry is only implemented for AArch64 however.
My use case requires both AArch64 and X86 to be supported.
