--- Comment #5 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Author: rsandifo Date: Thu Sep 5 07:50:07 2019 New Revision: 275399 URL: https://gcc.gnu.org/viewcvs?rev=275399&root=gcc&view=rev Log: Force IFN_LOAD/STORE_LANES operands to be memory (PR91577) This patch uses the workaround Richi suggested in the PR: make discover_nonconstant_array_refs mark the source of an IFN_LOAD_LANES call and the destination of an IFN_STORE_LANES call as addressable, so that they don't end up being REG rtxes during expansion. I had to move the discover_nonconstant_array_refs call outside the currently_expanding_to_rtl block since otherwise mark_addressable just queues the decision for later. 2019-09-05 Richard Sandiford <richard.sandif...@arm.com> gcc/ PR middle-end/91577 * cfgexpand.c (discover_nonconstant_array_refs): Force the source of an IFN_LOAD_LANES call and the destination of an IFN_STORE_LANES call to be in memory. (pass_expand::execute): Call discover_nonconstant_array_refs before setting currently_expanding_to_rtl. gcc/testsuite/ PR middle-end/91577 * gfortran.dg/pr91577.f90: New test, taken from temporary_1.f90.
