Nice!
Here's the testset:
@testset "inconsistency, possible bug" begin
@testset "T: $T" for T ∈ (Float16, Float32, Float64, BigFloat)
@testset "literal `-1`" begin
@test -0.0 === Float64(T(-Inf)^-1)
end
@testset "`Int(-1)`" begin
@test -0.0 === Float64(T(-Inf)^Int(-1))
end
end
endTrying it locally shows that the inconsistency is gone with the PR.

Looks sane to me. I've resolved a conflict and hope this will now pass CI

fixes #55831
Turns out all we needed was to change the xnlo initialization. @nsajko mind if I steal your testset?
