--- Comment #6 from anlauf at gcc dot gnu.org --- (In reply to martin from comment #5) > Just a question: Was this a pure diagnostic problem or did the contiguous > flag got lost also in the real code generation. The temporary associate variable p_ did miss the contiguous flag. > The output line with 3x "T" > suggests that code generation was fine Well, if you try the committed testcase and use -fdump-tree-original, you can see a runtime version of is_contiguous being inlined, which determines that p_ is actually contiguous. > (like in a call to a subroutine which > requires a contiguous array as argument and as a consequence a temporary > array is created due to the missing contiguous flag)? Depends. It could happen that argument packing is called, creating a temporary array. There are options to check this, e.g. -Warray-temporaries (at compile-time) and -fcheck=array-temps (runtime). Do not expect them to be too reliable.
