Bug ID: 16560
Summary: getSourceRange() for InitListExpr does not return full
range for vector initliazation
Product: clang
Version: 3.2
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P

I'm getting some strange behaviour, when I'm trying to get source range for
vector initalizations.
I have declaration (in global scope):
__constant float4 base_factor = (float4)(1.0f,2.0f,3.0f,4.0f);
Which is parsed to following AST:
(InitListExpr 0x7f8a9bcd3cf0 'float4':'float
__attribute__((ext_vector_type(4)))'
(FloatingLiteral 0x7f8a9bcd3c18 'float' 1.000000e+00)
(FloatingLiteral 0x7f8a9bcd3c38 'float' 2.000000e+00)
(FloatingLiteral 0x7f8a9bcd3c58 'float' 3.000000e+00)
(FloatingLiteral 0x7f8a9bcd3c78 'float' 4.000000e+00))
However when I'm trying to get them as string from rewriter with
getRewrittenText(init->getSourceRange())
I get only the first parenthesis:
(float4)
As a comparison, when I test normal table initialization everything seems fine:
__constant float base_table[] = { 1.0f,2.0f,3.0f,4.0f };
(InitListExpr 0x7fb470cd3fe8 '__constant float [4]'
(FloatingLiteral 0x7fb470cd3f08 'float' 1.000000e+00)
(FloatingLiteral 0x7fb470cd3f28 'float' 2.000000e+00)
(FloatingLiteral 0x7fb470cd3f48 'float' 3.000000e+00)
(FloatingLiteral 0x7fb470cd3f68 'float' 4.000000e+00))
Source location returns: { 1,2,3,4 }
Sounds like a similar problem to http://llvm.org/bugs/show_bug.cgi?id=3365 ,
which was fixed few years ago.
Thanks, Mikael
