Subject: [PATCH]: Fix static-pie on Hurd target
Date: Sun, 23 Oct 2022 11:34:54 +0200 [thread overview]
Message-ID: <20221023093454.7et6anfgzksfssxg@begin> (raw)
In-Reply-To: <20220829003040.kfgr7epzzyavbsjm@begin>
When linking with -static-pie, we need to use rcrt0.o (and grcrt0.o for
-pg). Also, set static:crt0.o before pie:Scrt1.o, otherwise -static -pie
fails to link with Scrt1.o due to missing _DYNAMIC symbol.
Also, -static-pie needs crtbeginS.o (otherwise it contains a relocation
in read-only .text).
And eventually, when HAVE_LD_PIE is not defined, there is no reason to
include the pie case
gcc/ChangeLog
* gcc/config/i386/gnu.h (STARTFILE_SPEC): Add static-pie cases
and fix -static -pie case.
