Subject: add array access function in the right order
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ce6a2c929e629df9e40cc99001c3fadeb0c687cd;p=gcc.git

add array access function in the right order

we used to add the access functions in the wrong order, Fortran style, leading to unprofitable interchanges.

	* graphite-sese-to-poly.c (pdr_add_memory_accesses): Iterate in
	the same order as adding data reference access functions.
