Bug ID: 98121
Summary: __attribute__ ((used)) should not imply
SHF_RETAIN_SECTION
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: fw at gcc dot gnu.org
Target Milestone: ---
The used attribute has already a defined meaning. I think it's wrong to cause
it to change section attributes because people use it to interface with
assembler code, so section flags conflicts are rather likely.
Using a separate attribute would also avoid the need for the configure check in
GCC.
This is related to this commit (note the date is off, it's actually GCC 11
only):
