Bug ID: 81498
Summary: Support build static PIE
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Target Milestone: ---
Glibc hjl/pie/static branch at
https://sourceware.org/git/?p=glibc.git;a=shortlog;h=refs/heads/hjl/pie/static
supports static PIE, which is similar to static executable, but can be loaded
at any address without a dynamic linker:
