Subject: [PATCH 4/9] ia64: Don't add crtfastmath.o for -shared
Date: Fri, 13 Jan 2023 09:00:59 +0100 (CET) [thread overview]
Message-ID: <20230113080100.2837913913@imap2.suse-dmz.suse.de> (raw)
Don't add crtfastmath.o for -shared to avoid altering the FP
environment when loading a shared library.
There's no maintainer listed for ia64, I'll push this myself as
obvious as last part of the series.
PR target/55522
* config/ia64/linux.h (ENDFILE_SPEC): Don't add crtfastmath.o
for -shared.
