Bug ID: 109245
Summary: aarch64 gcc defaults to -moutline-atomics but symbol
‘__aarch64_swp4_sync’ is hidden in libgcc.a
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: songmz1999 at foxmail dot com
Target Milestone: ---
I found an issue when compiling the connection process using the toolchain
aarch64_gcc12.2.0_glibc2.31.0_fp with the error message:
~/aarch64_gcc12.2.0_glibc2.31.0_fp/aarch64-unknown-linux-gnueabi/bin/.ld:
../../../deploy/oms/bin/omsservice: hidden symbol `__aarch64_swp4_sync' in
~/aarch64_gcc12.2.0_glibc2.31.0_fp/bin/../lib/gcc/aarch64-unknown-linux-gnueabi/12.2.0/libgcc.a(swp_4_5.o)
is referenced by DSO
~/aarch64_gcc12.2.0_glibc2.31.0_fp/aarch64-unknown-linux-gnueabi/bin/.ld: final
link failed: bad value
The solution I've found so far is to enable the -mno-outline-atomics parameter
at compile time. But why does gcc have -moutline-atomics enabled by default,
but when calling the function '__aarch64_swp4_sync', it is hidden in libgcc.a?
Is there a better solution?

That means one or more of your shared libraries has been linked incorrectly,
e.g. by using ld -shared by hand instead of gcc -shared, or with -nostdlib or
something similar.

Can you show how you are doing the link? If you are linking in shared
libraries, show how you are linking those too?

No feedback in almost 11 months on the command line which is failing and about
how the shared libraries were linked so closing as invalid.
