From: "andi-gcc at firstfloor dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/50824] New: memset or memcpy on structure prevents SRA Date: Fri, 21 Oct 2011 15:26:00 -0000 [thread overview] Message-ID: <bug-50824-4@http.gcc.gnu.org/bugzilla/> (raw) http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50824 Bug #: 50824 Summary: memset or memcpy on structure prevents SRA Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: tree-optimization AssignedTo: unassigned@gcc.gnu.org ReportedBy: andi-gcc@firstfloor.org Clearing a structure using memset or copying it using memcpy currently disables SRA for the structure because it counts as escaping. Since this is common it would be better if it was handled. Clearing it using an initializer or copying it with = already works, so those could be handled the same way.
