From 126adc89d8a32193df075ce665e76ad95ebd0557 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 19 Dec 2017 13:51:01 -0800 Subject: [PATCH] Document that --enable-static-pie implies PIE To build static PIE, all .o files are compiled with -fPIE. Since --enable-static-pie is designed to provide additional security hardening benefits, it also implies that glibc programs and tests are created as dynamic position independent executables (PIE) by default for better security hardening.
