From 952b7630c72ae245f370f1a2bcaade82bb1f7361 Mon Sep 17 00:00:00 2001 From: Xi Ruoyao Date: Sun, 26 Mar 2023 19:13:34 +0800 Subject: [PATCH] LoongArch: ldconfig: Ignore EF_LARCH_OBJABI_V1 in shared objects Binutils 2.40 sets EF_LARCH_OBJABI_V1 for shared objects: $ ld --version | head -n1 GNU ld (GNU Binutils) 2.40 $ echo 'int dummy;' > dummy.c $ cc dummy.c -shared $ readelf -h a.out | grep Flags Flags: 0x43, DOUBLE-FLOAT, OBJ-v1 We need to ignore it in ldconfig or ldconfig will consider all shared objects linked by Binutils 2.40 "unsupported". Maybe we should stop setting EF_LARCH_OBJABI_V1 for shared objects, but Binutils 2.40 is already released and we cannot change it. --- sysdeps/unix/sysv/linux/loongarch/readelflib.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sysdeps/unix/sysv/linux/loongarch/readelflib.c b/sysdeps/unix/sysv/linux/loongarch/readelflib.c index bcaff86b36..ceba355959 100644 --- a/sysdeps/unix/sysv/linux/loongarch/readelflib.c +++ b/sysdeps/unix/sysv/linux/loongarch/readelflib.c @@ -40,7 +40,7 @@ process_elf_file (const char *file_name, const char *lib, int *flag, ret = process_elf64_file (file_name, lib, flag, isa_level, soname, file_contents, file_length); - flags = elf64_header->e_flags; + flags = elf64_header->e_flags & ~EF_LARCH_OBJABI_V1; /* LoongArch linkers encode the floating point ABI as part of the ELF headers. */ switch (flags & SUPPORTED_ELF_FLAGS) -- 2.11.4.GIT
