The following routines in libgcc on hppa are provided by glibc:
dave@mx3210:~/gnu/gcc/objdir/hppa-linux-gnu/libgcc$ nm libgcc_s.so.4|grep " U "
U abort@GLIBC_2.2
U calloc@GLIBC_2.2
U _dl_find_object@GLIBC_2.35
U free@GLIBC_2.2
U malloc@GLIBC_2.2
U memcpy@GLIBC_2.2
U memmove@GLIBC_2.2
U memset@GLIBC_2.2
U pthread_cond_broadcast@GLIBC_2.3.2
U pthread_cond_wait@GLIBC_2.3.2
U pthread_getspecific@GLIBC_2.34
U pthread_key_create@GLIBC_2.34
U pthread_mutex_lock@GLIBC_2.2
U pthread_mutex_unlock@GLIBC_2.2
U pthread_once@GLIBC_2.34
U pthread_setspecific@GLIBC_2.34
U realloc@GLIBC_2.2
U strlen@GLIBC_2.2
If any of these are implemented in qemu, they also may need the attribute fix.
