Hi,
I am trying to understand internals of
autovectorization.
It is given that autovectorization sarts with
vectorize_loops(struct loops *loops) function in
tree-vectoriztion.c. I tried to understand the
definitions of 'struct loops' and 'struct loop'.
But much information is not given.
Where can I find more information????
For example struct loops is defined as:
struct loops
{
/* Number of natural loops in the function. */
unsigned num;
.
.
.
.
/* Headers shared by multiple loops that should be
merged. */
sbitmap shared_headers;
};
But I want to understand what exactly is sbitmap and
to what it is pointing . How can I know that?
Thanks in advance.
