            Bug ID: 265218
           Summary: REGRESSION(270651 at main): Broke cloop build:
                    LowLevelInterpreter.asm:2778 in call to entry: Could
                    not find macro entry (MacroError)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

This is sort of a regression from 270651 at main. When building for x86_64 with -DENABLE_JIT=OFF -DENABLE_C_LOOP=ON -DENABLE_SAMPLING_PROFILER=OFF we hit this error:

[266/494] Generating ../../JavaScriptCore/DerivedSources/LLIntDesiredOffsets.h
FAILED: JavaScriptCore/DerivedSources/LLIntDesiredOffsets.h /home/mcatanzaro/Projects/WebKit/WebKitBuild/JSCOnly/JavaScriptCore/DerivedSources/LLIntDesiredOffsets.h 
cd /home/mcatanzaro/Projects/WebKit/WebKitBuild/JSCOnly/Source/JavaScriptCore && /usr/bin/ruby /home/mcatanzaro/Projects/WebKit/Source/JavaScriptCore/offlineasm/generate_offset_extractor.rb -I/home/mcatanzaro/Projects/WebKit/WebKitBuild/JSCOnly/JavaScriptCore/DerivedSources/ /home/mcatanzaro/Projects/WebKit/Source/JavaScriptCore/llint/LowLevelInterpreter.asm /home/mcatanzaro/Projects/WebKit/WebKitBuild/JSCOnly/bin/LLIntSettingsExtractor /home/mcatanzaro/Projects/WebKit/WebKitBuild/JSCOnly/JavaScriptCore/DerivedSources/LLIntDesiredOffsets.h C_LOOP normal
LowLevelInterpreter.asm:2778 in call to entry: Could not find macro entry (MacroError)

Problem is here:

entry(wasm, macro()
    include InitWasm
end)

The entry macro is defined only when C_LOOP and C_LOOP_WIN are both disabled, but this new code in the WEBASSEMBLY condition uses it unconditionally. Should WebAssembly be disabled when C_LOOP is enabled, or is there another possible fix?
