Since libgcj.so isn't on the linker command line, gold resolves _Jv_RegisterClasses to 0 and ld silently resolves it to _Jv_RegisterClasses in libgcj.so: [hjl@gnu-13 testsuite]$ readelf -sWr /tmp/PR16923.gold | grep _Jv_RegisterClasses 8: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _Jv_RegisterClasses 37: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _Jv_RegisterClasses [hjl@gnu-13 testsuite]$ readelf -sWr /tmp/PR16923.bfd | grep _Jv_RegisterClasses 0000000000600cd0 0000000900000007 R_X86_64_JUMP_SLOT 00000000004005e0 _Jv_RegisterClasses + 0 9: 00000000004005e0 0 FUNC WEAK DEFAULT UND _Jv_RegisterClasses 59: 00000000004005e0 0 FUNC WEAK DEFAULT UND _Jv_RegisterClasses [hjl@gnu-13 testsuite]$ ^ permalink raw reply [flat|nested] 3+ messages in thread
