CodeOrigin changes and now is defined as a class. 


```
-struct CodeOrigin {
-    static const unsigned invalidBytecodeIndex = UINT_MAX;
-    
-    // Bytecode offset that you'd use to re-execute this instruction, and the
-    // bytecode index of the bytecode instruction that produces some result that
-    // you're interested in (used for mapping Nodes whose values you're using
-    // to bytecode instructions that have the appropriate value profile).
-    unsigned bytecodeIndex;
-    
-    InlineCallFrame* inlineCallFrame;
-    
+class CodeOrigin {
+public:
...
```

... bytecodeIndex is now defined as function


```
...
+    unsigned bytecodeIndex() const
+    {
+#if CPU(ADDRESS64)
+        if (!isSet())
+            return s_invalidBytecodeIndex;
+        if (UNLIKELY(isOutOfLine()))
+            return outOfLineCodeOrigin()->bytecodeIndex;
+        return m_compositeValue >> (64 - s_freeBitsAtTop);
+#else
+        return m_bytecodeIndex;
+#endif
+    }

```

Can you please provide a dump of the build failure?  According to the WPE EWS on https://bugs.webkit.org/show_bug.cgi?id=195928, it seemed to build fine.

OK, I see what the issue is.  It's not a WPE build issue, but a 32-bit build issue.

Please retitle this bug to say "32-bit build failure after r243232".

Ahh, yes. I expressed myself poorly. I saw the problem in the ARMv7 JSCore bots for WPE https://build.webkit.org/waterfall?category=misc but probably appeared in other 32-bits bots as well.
