- Subject: RTL alias annotation
Hello,
I'd like to know the meaning of alias annotations occuring in RTL. For
example, in
(mem/f:SI
(plus:SI (reg/f:SI 6 ebp)
(const_int -4 [0xfffffffc])) [0 name+0 S4 A32])
what do 0, S4, and A32 in [0 name+0 S4 A32] mean?
Another question is does gcc perform inter-procedural alias-analysis? If
it does, does it emit some information of it in the RTL?
Rgds,
Iman Narasamdya
