hi all,
does libc.a exclusively uses the traditional 'int $0x80' method
to make a system call or is it using sysenter too ?
when I check the static objects compiled when building glibc,
I see that ENTER_KERNEL is sometimes translated to 'int 0x80'
and sometimes to 'call *0x0' which i think is 'call *_dl_sysinfo'.
thank you
