Subject: [PATCH] Use Pcrt1.o%s/gPcrt1.o%s for -static-pie
Date: Sun, 15 Oct 2017 18:09:00 -0000 [thread overview]
Message-ID: <20171015131657.GA24340@gmail.com> (raw)
crt1.o is used to create dynamic and non-PIE static executables. Static
PIE needs to link with Pcrt1.o, instead of crt1.o, to relocate static PIE
at run-time. When -pg is used with -static-pie, gPcrt1.o should be used.
Tested on x86-64. OK for master?
Thanks.
H.J.
