Bug ID: 110320
Summary: ELFv2 pc-rel ABI extension allows using r2 as a
volatile register
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: bergner at gcc dot gnu.org
Target Milestone: ---
The PC-Relative ABI extension to the ELFv2 ABI defines register r2 (normally
the TOC register in ELFv1 & ELFv2) as a volatile register available for use in
the register allocator. Currently GCC doesn't make use of that fact, so this
is a missed-optimization opportunity.
