Subject: [PATCH v2 9/9] gcc: Fix specs generation for ARC
Date: Thu, 20 Sep 2018 23:42:32 +0300 [thread overview]
Message-ID: <20180920204232.10583-10-abrodkin@synopsys.com> (raw)
In-Reply-To: <20180920204232.10583-1-abrodkin@synopsys.com>
GCC's built-in spec for LD is missing a space after
"--eh-frame-hdr" thus with the next option merged together they
are not understood by LD and so LD fails.
Back-port from upstream GCC, see:
https://github.com/gcc-mirror/gcc/commit/892142379c6b99fe8c3ebdfe0b79e2a435228c1d

+Subject: [PATCH] [ARC] Update LINK_EH_SPEC linker spec.
+
+With no trailing space in LINK_EH_SPEC linker spec gets generated as:
+------------------------>8---------------------
+%{!r:--build-id} --eh-frame-hdr%{h*} ...
+------------------------>8---------------------
+
+or even worse if hash style is added:
+------------------------>8---------------------
+%{!r:--build-id} --eh-frame-hdr--hash-style=sysv %{h*} ...
+------------------------>8---------------------
+
+Now if that spec is really used by LD then it fails inevitably
+saying that it doesn't know option "--eh-frame-hdr--hash-style=sysv".
