[cfe-dev] can we know if an array definition has an explicit size ??

[Journeyer J. Joh]

Hello Sean Silva, kevinlynx

In my previous study,
- an AST node of an array is composed of clang::TypeSourceInfo and identifier.
- clang::TypeSourceInfo is composed of clang::Type and clang::TypeLoc.
- identifier is the name of the array(variable).

Best regards
Journeyer

PS. This is not a proven info but just one of my study result.
