The current version of GDB doesn't correctly support displaying the
SSE registers for debugging multi-threaded programs. This is due to
the fact that the current version of libthread_db doesn't provide the
means to track these registers. Browsing through the code it seems
that td_thr_getxregs(), td_thr_getxregsize() and td_thr_setxregs() are
intended to be used for supporting extra register sets. It seems that
these calls are unused on Solaris x86. Would it be OK to provide an
implementation of these calls for Linux x86 that manages the SSE
registers?
