Bug ID: 17082
Summary: The variable declaration in a catch() does not appear
in -ast-dump
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: [email protected]

Classification: Unclassified
$ cat /tmp/a.cc
void f() {
try {
}
catch(int x) {
}
}
$ clang -Xclang -ast-dump /tmp/a.cc -c
TranslationUnitDecl 0x47ccf00 <<invalid sloc>>
|-TypedefDecl 0x47cd440 <<invalid sloc>> __int128_t '__int128'
|-TypedefDecl 0x47cd4a0 <<invalid sloc>> __uint128_t 'unsigned __int128'
|-TypedefDecl 0x47cd860 <<invalid sloc>> __builtin_va_list '__va_list_tag [1]'
`-FunctionDecl 0x47cd900 </tmp/a.cc:1:1, line:6:1> f 'void (void)'
`-CompoundStmt 0x47cda80 <line:1:10, line:6:1>
`-CXXTryStmt 0x47cda60 <line:2:3, line:5:3>
|-CompoundStmt 0x47cd9a0 <line:2:7, line:3:3>
`-CXXCatchStmt 0x47cda40 <line:4:3, line:5:3>
`-CompoundStmt 0x47cda28 <line:4:16, line:5:3>
The variable x is not visible anywhere in the above dump. This is because it is
stored as a VarDecl in the CXXCatchStmt. I guess it should be wrapped in a
DeclStmt so that we can easily iterate over it.
