Bug ID: 119557
Summary: malloc attribute on function decls and merging
interaction with LTO
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: documentation, lto
Severity: enhancement
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
I am not 100% sure this is just a documentation issue or there needs some
changes to be done with respect to maybe adding noinline when malloc attribute
different between 2 TUs.
An exmple is PR 117315. Even though the malloc attribute is included on the TU
that has the malloc attribute on it but even if we remove it from the TU which
has the definition of the function that might become well defined?
This came up when I was thinking about clang's not_tail_called attribute and
how to handle merging the decl for LTO.
