As we'll hopefully move away from using intrinsics for debug-info shortly, this commit stabilizes a few tests to avoid spurious changes in the process. Briefly, there are differences in output when we don't use intrinsics that we're going to suppress in case we have to revert, these are: * The attributor test gets different attributes for the dbg.value intrinsic because it's not present during optimisation. This has no functional effect and there's no need to test for it. * The Scalarizer test exposes a "debug-info affects codegen" problem, but fixing it is fiddly (updating 20 IRBuilder object calls). Pin this test to not change with RemoveDIs, we can relax it later and get the correct behaviour. * DIDefaultTemplateParam.ll tests for explicit metadata node numbers which is generally bad. Add explicit node-number capturing CHECK lines.

; FIXME: the test output here changes if we use the RemoveDIs non-intrinsic
|
|
; debug-info format for the test. Specifically, the intrinsics no longer
|
|
; interfere with the scalarizer, and we get the same code with/without
|
|
; debug-info.
|
|
; That's the behaviour we want; but fix this test to only use intrinsics as
|
|
; we introduce the non-intrinsic format, to reduce the amount of spurious test
|
|
; changes it comes with. We can turn that off once we're committed to using
|
|
; the non-intrinsic format.
