Bug #: 53017
Summary: Integer constant not constant enough for vector_size
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: marc.glisse@normalesup.org
In the following code, s is apparently not an acceptable parameter for the
vector_size attribute, but s+0 is.
constexpr int s=32;
typedef double VEC __attribute__ ((__vector_size__ (s
#ifndef BUG
+ 0
#endif
)));
VEC a={2.,3.,4.};
$ g++ -std=c++0x v.cc -Wall -W -c -O3
$ g++ -std=c++0x v.cc -Wall -W -c -O3 -DBUG
v.cc:6:4: warning: '__vector_size__' attribute ignored [-Wattributes]
v.cc:8:16: error: scalar object 'a' requires one element in initializer
