Hi Richard, Here is a discussion we did some time ago https://gcc.gnu.org/pipermail/gcc/2019-January/227834.html please see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88877 for more info regarding the bug.
We incorporated below Jakub's suggestion in this patch. Jakub wrote: "" Yeah, all the callers of emit_library_call* would need to be changed to pass triplets rtx, machine_mode, int/bool /*unsignedp*/, instead of just rtx_mode_t pair.
