Bug #: 53254
Summary: Missed opportunity to aggregate consecutive stores
into single larger store
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: law@redhat.com
struct X {
X();
char a,b,c,d,e,f,g,h;
long long l;
};
X::X() : a(0), b(0), c(0), d(0), e(0), f(0), g(0), h(0), l(0)
{}
Compile with -O2. Ideally we'd issue quadword stores. I'm told VC++ manages
to get this right.

An obvious dup of bug 19726.
