; REQUIRES: pollyacc
; When we have `-polly-ignore-parameter-bounds`, `Scop::Context` does not contain
; all the parameters present in the program.
;
; The construction of the `isl_multi_pw_aff` requires all the indivisual `pw_aff`
; to have the same parameter dimensions. To achieve this, we used to realign
; every `pw_aff` with `Scop::Context`. However, in conjunction with
; `-polly-ignore-parameter-bounds`, this is now incorrect, since `Scop::Context`
; does not contain all parameters.
;
; We check that Polly does the right thing in this case and sets up the parameter
; dimensions correctly.
; Check that kernel launch is generated in host IR.
; the declare would not be generated unless a call to a kernel exists.
