Hi all,
In #gcc, it was suggested to use referenced vars to get all the
referenced vars for a function. I added to my IPA pass props,
PROP_referenced_vars , used push_cfun and then
FOR_EACH_REFERENCED_VAR, however, it just segfaults in
tree-flow-inline.h:34 :
hti->slot = table->entries;
It was said gimple was lowered and referenced vars created before IPA
passes but I guess not due to the segfault. :(
Is there a way to get the referenced vars?
This was all due to the fact that I wished to get a list of
referenced vars in my pass, so I was going through all the basic
blocks and statements, then found out that...
int x;
{
int y;
{
int z;
...
}
...
}
just happens to have three statements, all VAR_DECL,x, y, z, without
any reference to the starting and ending blocks. As a side question,
how can I get hand of where the blocks start and finish? Don't really
know if it's useful but If I need it later, better I know how.
Cheers,
