Why is LinearAlgebra.pinv not type stable? Can it be implemented in a type stable way? Example (thanks to @albheim ) using LinearAlgebra using JET function test(M) A = rand(M, M + 2) pinv(A) end test(10) report = @report_opt test(10) println(report) … ││┌ pinv(A::Matrix{Float64}; atol:…

Methods with keyword arguments are implemented to call hidden helper methods that have the written body, so @code_warntype is really difficult to use with them. Well, I dug out the underlying call and am including the part where things get a little unstable, even though the internal arrays and the …
