If so how It's weird, because it seems that vsyscalls are only done by x86_64, all others archs have only vdso... so they seem to forget about statically linked apps... > > are statically programs going to be handled ? > > Unfortunately the vsyscalls cannot ever go completely away. > Statically linked apps, the bane of progress, will need them. Actually if we could easily retrieve the vdso in a process memory mapping (through a new syscall or /proc/self/maps), it should be easy for gcc/ld to statically links vdso functions into a statically linked app, shouldn't it ? -- Francis
