> Uli Weigand discovered that the gcc.target/powerpc/swaps-p8-21.c test case fails when large and small code models are used, rather than the default medium code model. This is because analyze_swaps is determining whether the mask used for a vperm insn is loaded from the constant pool, and there is an extra indirection for such loads when the large or small code model is used. This patch changes analyze_swaps to handle the extra indirection correctly. A new test case variant is added to check for it.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no regressions. Ok for trunk? Thanks, Bill [gcc] 2015-12-01 Bill Schmidt <wschm...@linux.vnet.ibm.com> * config/rs6000/rs6000.c (const_load_sequence_p): Handle extra indirection for large and small code models. (adjust_vperm): Likewise. [gcc/testsuite] 2015-12-01 Bill Schmidt <wschm...@linux.vnet.ibm.com> * gcc.target/powerpc/swaps-p8-22.c: New. Okay. Thanks, David
