Szabolcs Nagy f2435263d7 make relocation time symbol lookup and dlsym consistent ... Using common code path for all symbol lookups fixes three dlsym issues: - st_shndx of STT_TLS symbols were not checked and thus an undefined tls symbol reference could be incorrectly treated as a definition (the sysv hash lookup returns undefined symbols, gnu does not, so should be rare in practice). - symbol binding was not checked so a hidden symbol may be returned (in principle STB_LOCAL symbols may appear in the dynamic symbol table for hidden symbols, but linkers most likely don't produce it). - mips specific behaviour was not applied (ARCH_SYM_REJECT_UND) so undefined symbols may be returned on mips. always_inline is used to avoid relocation performance regression, the code generation for find_sym should not be affected.		2019-08-12 18:25:38 -04:00
