The rationale seems to be based on the assumption that __tls_get_addr is exported for every architecture and hence an internal non-plt alias is needed. This is not true for s390 though, since it exports __tls_get_offset and not __tls_get_addr. This results in tst-audit9 being stuck in an infinite loop. This patch fixes this by defining a __tls_get_addr macro to itself so as to not use the conflicting declaration. --- diff --git a/ChangeLog b/ChangeLog index 2b65e02..33e232c 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2015-01-14 Siddhesh Poyarekar + + * sysdeps/s390/dl-tls.h [IS_IN (rtld)]: Define __tls_get_addr + macro. + 2015-01-13 Adhemerval Zanella * sysdeps/powerpc/powerpc64/power7/memcmp.S (memcmp): Fix performance diff --git a/sysdeps/s390/dl-tls.h b/sysdeps/s390/dl-tls.h index 0fa8045..8132b10 100644 --- a/sysdeps/s390/dl-tls.h +++ b/sysdeps/s390/dl-tls.h @@ -33,6 +33,13 @@ extern unsigned long __tls_get_offset (unsigned long got_offset); # include +/* dl-tls.c declares __tls_get_addr as an exported symbol if it is not defined + as a macro.
