Conditional analysis before inliner
Thanks for the answer Eli.
I think I was a little too vague in my question. The program has the
following structure:
void foo() {
bar();
}
void bar() {
for (..) {
__builtin_compute()
}
}
We would like to use scalar evolution + loopinfowrapperpass inside
instcombine only if __builtin_compute is present. instcombine can convert
the loop into a single builtin ie.
void bar() {
__builtin_wide_compute();
}
When the inliner runs on foo(), we want bar() to already have the
tra...

Conditional analysis before inliner
Hi,
I have pass phase ordering question.
I am interested in performing a transformation that matches several LLVM IR
instructions and converts them to a single builtin. This sort of
transformation must occur prior to inlining because inlining needs to
analyze cost of the builtin. However, the LLVM IR -> builtin transformation
requires scalar evolution which typically doesn't run until
