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