https://bugs.llvm.org/show_bug.cgi?id=40853
Bug ID: 40853
Summary: Enable overflow intrinsic vectorization support
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P

Now that vector versions of the *.overflow intrinsics are supported we need to
add vectorization support.
For instance, in SLP BoUpSLP::canMapToVector can't handle the return struct
type:
{i32, i1} @llvm.sadd.with.overflow.i32(i32 %a, i32 %b)
to
{<4 x i32>, <4 x i1>} @llvm.sadd.with.overflow.v4i32(<4 x i32> %a, <4 x i32>
%b)
The LV has similar issues.

Priority: P
Component: Interprocedural Optimizations
Assignee: unassignedb...@nondot.org

int square(int x) {

int add(int x) {
return x + x;
}
typedef int (*p) (int);
p arr[4] = {square, add};
int test(int x) {
int res = arr[1](x);
return res;
}
Expected:
test(int):
lea eax, [rdi+rdi]
ret
Currently:
test(int):
jmp [QWORD PTR arr[rip+8]]
If the index to the jump table isn't a constant, should not be better to expand
"if else" chain like:
if (x==1) arr[1](x);
else if (x==2) arr[2](x);
..and then take an opportunity to inline functions?
