Are SCEV normal form?
Hello,
I assumed SCEV purpose was to be a normal form, but then I wondered which
one of those is the normal form:
(zext i16 (trunc i32 %a to i16) to i32)
vs
(-((%a /u 65536) *u 65536) + %a)
The first one is nice for interval analysis, and known bit analysis.
The second one is nice when plugged into gep of 2d arrays.
