[PATCH] introduce effective-target fold_memcpy

2019-01-18 Thread Martin Sebor
Some of the -Warray-bounds and -Wrestrict tests are prone to failing on targets like arm-eabi and others that use different parameters to decide which memcpy calls should be folded to MEM_REF (those that do are copies of small power-of-two sizes where the power tends to vary from target to target
