* [Bug libgcc/109245] New: aarch64 gcc defaults to -moutline-atomics but symbol ‘__aarch64_swp4_sync’ is hidden in libgcc.a @ 2023-03-22 9:53 songmz1999 at foxmail dot com 2023-03-22 9:58 ` [Bug libgcc/109245] " jakub at gcc dot gnu.org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: songmz1999 at foxmail dot com @ 2023-03-22 9:53 UTC (permalink / raw) To: gcc-bugs https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109245 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? ^ permalink raw reply [flat|nested] 5+ messages in thread
