Bug ID: 100937
Summary: configure: Add --enable-default-semantic-interposition
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: i at maskray dot me
Target Milestone: ---
Add a configure option --enable-default-semantic-interposition to customize
-f(no-)semantic-interposition default.
The suppression of interprocedural optimizations and inlining for such
default visibility non-vague-linkage function definitions is the biggest
difference between -fPIE/-fPIC.
Distributions may want to enable default -fno-semantic-interposition to
reclaim the lost performance from -fPIC (e.g. CPython is said to be 27% faster;
Clang is 3% faster).
