m68k is a non-PI_STATIC_AND_HIDDEN arch which uses a GOT relocation when loading the address of a jump table. The GOT load may be reordered before processing R_68K_RELATIVE relocations, leading to an unrelocated/incorrect jump table, which will cause a crash. The foolproof approach is to add an optimization barrier (e.g. calling an non-inlinable function after relative relocations are resolved). That is non-trivial given the current code structure, so just use the simple approach to avoid the jump table: handle only the essential reloctions for RTLD_BOOTSTRAP code. This is based on Andreas Schwab's patch and fixed ld.so crash on m68k. Reviewed-by: Adheemrval Zanella <adhemerval.zanella@linaro.org> |
