            Bug ID: 242301
           Summary: Rename offlineasm's asm.deferAction to
                    asm.deferOSDarwinAction.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

Similarly, rename the underlying field from @deferredAction to @deferredOSDarwinAction.  This deferAction was only used for OS(DARWIN) anyway.  By changing it to be OS(DARWIN) specific to indicate its actual usage, we can make the generated LLIntAssembly.h more readable and efficient.

Previously, we emit this code:

      OFFLINE_ASM_GLOBAL_LABEL(llintPCRangeEnd)
      #if OS(DARWIN)
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_1, Ljsc_llint_loh_ldr_1 \n"
      #endif
      #if OS(DARWIN)
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_2, Ljsc_llint_loh_ldr_2 \n"
      #endif
      ...
      #if OS(DARWIN)
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_2308, Ljsc_llint_loh_ldr_2308 \n"
      #endif
      OFFLINE_ASM_END

Now, we emit this instead:

      OFFLINE_ASM_GLOBAL_LABEL(llintPCRangeEnd)
      #if OS(DARWIN)
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_1, Ljsc_llint_loh_ldr_1 \n"
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_2, Ljsc_llint_loh_ldr_2 \n"
          ...
          ".loh AdrpLdrGot Ljsc_llint_loh_adrp_2308, Ljsc_llint_loh_ldr_2308 \n"
      #endif // OS(DARWIN)
      OFFLINE_ASM_END
