Bug #: 51700
Summary: Cannot subscript packed vector type in g++ (works in
C)
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: nicholasbishop@gmail.com
Example code (full program):
typedef int v4si __attribute__ ((vector_size (16)));
int main() {
v4si x;
x[0] = 33;
return 0;
}
Compiling with gcc produces a working program and no console output, but g++
complains:
$ gcc -Wall -Wextra vecbug.c
$ g++ -Wall -Wextra vecbug.c
vecbug.c: In function ‘int main()’:
vecbug.c:4:5: error: invalid types ‘v4si {aka __vector(4) int}[int]’ for array
subscript
Verbose output:
$ g++ -v -Wall -Wextra vecbug.c
Using built-in specs.
