Bug ID: 34669
Summary: Provide -f-no-alias, opposite of -fno-strict-alias
Component: LLVM Codegen
Assignee: unassignedclangbugs at nondot.org
Reporter: ag at arvid.io
CC: llvm-bugs at lists.llvm.org
The '-fno-strict-alias' flag disables all alias semantics, which is useful for
some applications where these would be violated. The opposite of this would be
a useful addition, which would basically provide FORTRAN like aliasing
semantics for C / C++, by adding an implicit 'restrict' to every pointer.
