main.c: In function 'vgCallgrind_post_syscalltime':
main.c:1779:25: warning: '*((void *)&ts_now+8)'
may be used uninitialized in this function [-Wmaybe-uninitialized]
struct vki_timespec ts_now;
main.c:1779:25: warning: 'ts_now'
may be used uninitialized in this function [-Wmaybe-uninitialized]
In function collect_time the conditional expression in the switch
statement has type int (after integral promotions). GCC assumes that
it may have values other than the ones listed in the enumerated type
it was promoted from. In that case the memory pointed to by its 1st
argument remains unintialised. Later on vki_timespec_diff will read
the contents of ts_now undoditionally. Hence the warning.
Using the default case for the tl_assert () removes the warning and
makes the code more robust should another enumerator ever be added to
Collect_Systime.
