For this case in this patch in particular:
extern const char* bar;
const char* foo [] = {
"hello",
"goodbye",
bar
};
TranslationUnitDecl
|-VarDecl <line:1:1, col:20> col:20 used bar 'const char *' extern
`-VarDecl <line:2:1, line:6:1> line:2:13 foo 'const char *[3]' cinit
`-InitListExpr <col:22, line:6:1> 'const char *[3]'
|-ImplicitCastExpr <line:3:5> 'const char *' <NoOp>
| `-ImplicitCastExpr <col:5> 'char *' <ArrayToPointerDecay>
| `-StringLiteral <col:5> 'char[6]' lvalue "hello"
|-ImplicitCastExpr <line:4:5> 'const char *' <NoOp>
| `-ImplicitCastExpr <col:5> 'char *' <ArrayToPointerDecay>
| `-StringLiteral <col:5> 'char[8]' lvalue "goodbye"
`-ImplicitCastExpr <line:5:5> 'const char *' <LValueToRValue>
`-DeclRefExpr <col:5> 'const char *' lvalue Var 0x55b64410c270 'bar'
'const char *'
so if you were concerned with arrays <https://reviews.llvm.org/D76096#4523828>
of string literals <https://reviews.llvm.org/D76096#4524003>, we need this
patch.
