This is only failed with C. But not for C++. So I don't think we have problem
for Seam. I may missing something...
The different is in reprehensive of enum type between c vs c++:
For C:
| -EnumDecl 0x1193f838 <line:18:9, line:33:1> line:18:14 omp_allocator_handle_t
|
|
| -EnumConstantDecl 0x1193f940 <line:19:3, col:24> col:3 referenced
omp_null_allocator 'int' |
|
| `-ConstantExpr 0x1193f920 <col:24> 'int'
|
|
|
| -value: Int 0 |
|
| `-IntegerLiteral 0x1193f900 <col:24> 'int' 0
|
|
| -EnumConstantDecl 0x1193f9d0 <line:20:7, col:31> col:7 referenced
omp_default_mem_alloc 'int' |
|
| `-ConstantExpr 0x1193f9b0 <col:31> 'int'
|
|
|
| -value: Int 1 |
|
| `-IntegerLiteral 0x1193f990 <col:31> 'int' 1
|
|
for C++:
| -EnumDecl 0x11b31d88 <line:18:9, line:33:1> line:18:14 omp_allocator_handle_t
|
|
| -EnumConstantDecl 0x11b31e90 <line:19:3, col:24> col:3 referenced
omp_null_allocator 'omp_allocator_handle_t' |
|
| `-ImplicitCastExpr 0x11b4b770 <col:24> 'unsigned long' <IntegralCast>
|
|
| `-ConstantExpr 0x11b31e70 <col:24> 'int'
|
|
|
| -value: Int 0 |
|
| `-IntegerLiteral 0x11b31e50 <col:24> 'int' 0
|
|
| -EnumConstantDecl 0x11b31f20 <line:20:7, col:31> col:7 referenced
omp_default_mem_alloc 'omp_allocator_handle_t' |
|
| `-ImplicitCastExpr 0x11b4b788 <col:31> 'unsigned long' <IntegralCast>
|
|
| `-ConstantExpr 0x11b31f00 <col:31> 'int'
|
|
|
| -value: Int 1 |
|
| `-IntegerLiteral 0x11b31ee0 <col:31> 'int' 1
