rL347828: [PowerPC] [NFC] Add test cases to the ISD::BR_CC node in the instruction…
Summary

Add the following test case for the ISD::BR_CC node in the instruction selection

define i64 @testi64slt(i64 %c1, i64 %c2, i64 %c3, i64 %c4, i64 %a1, i64 %a2) #0 {
entry:
  %cmp1 = icmp eq i64 %c3, %c4
  %cmp3tmp = icmp eq i64 %c1, %c2
  %cmp3 = icmp slt i1 %cmp3tmp, %cmp1
  br i1 %cmp3, label %iftrue, label %iffalse
iftrue:
  ret i64 %a1
iffalse:
  ret i64 %a2
}

The data type i64 can be replaced by i32, i64, float, double
And condition codes can be replaced by: SETEQ, SETEN, SELT, SETLE, SETGT, SETGE,SETULT, SETULE, SSETGT, and SETUGE

You don't need create a review for the new added NFC test case. LGTM.

Personally, I don't like writing the test case using such script. Because, it will check all the instructions and make your test point unclear. And it hard code the register name, which make this test fragile。

@steven.zhang Thanks for pointing this out, i will consider it.

This makes maintenance of tests easier since anyone can re-run the script. Of course, the test case is very strictly specified which will make it sensitive to changes in codegen/regalloc/scheduling. However, it is arguably easier for someone to re-run the script and for reviewers to carefully review every aspect of the change than it would be if only specific instructions are checked. There is some value in tests being sensitive to changes not necessarily related to what they are testing - we may discover unintended changes that are actually detrimental.

As to the point about what the test case is actually testing, I think that is a valid concern and a comment should explain that.

Thank you for the detail explanation. So, there are Pro & Cons for both and they are targeting for different purpose. For this case, we shouldn't use this script as we have clear testing point.
