[cfe-dev] A question on initListExpr() matcher

[Farzad Sadeghi via cfe-dev]

Given the code provided below, why do i match each inner InitListExpr twice?
Here's the sample code:
void test14 (void)
{
	int arr[3][2] = {{2, 3}, {4, 5}, {6, 7}};
}
This is the AST:
`-FunctionDecl 0x59c09b0 <line:792:1, line:806:1> line:792:6 test14
'void (void)'
  `-CompoundStmt 0x59c2768 <line:793:1, line:806:1>
    |-DeclStmt 0x59c2330 <line:794:2, col:42>
    | `-VarDecl 0x59c1f80 <col:2, col:41> col:6 arr 'int [3][2]' cinit
    |   `-InitListExpr 0x59c21e8 <col:18, col:41> 'int [3][2]'
    |     |-InitListExpr 0x59c2240 <col:19, col:24> 'int [2]'
    |     | |-IntegerLiteral 0x59c1fe0 <col:20> 'int' 2
    |     | `-IntegerLiteral 0x59c2000 <col:23> 'int' 3
    |     |-InitListExpr 0x59c2290 <col:27, col:32> 'int [2]'
    |     | |-IntegerLiteral 0x59c2070 <col:28> 'int' 4
    |     | `-IntegerLiteral 0x59c2090 <col:31> 'int' 5
    |     `-InitListExpr 0x59c22e0 <col:35, col:40> 'int [2]'
    |       |-IntegerLiteral 0x59c2100 <col:36> 'int' 6
    |       `-IntegerLiteral 0x59c2120 <col:39> 'int' 7
This is the matcher im running on clang-query:
match initListExpr()
And this is the result i get:
