question about attribute aligned for functions

2018-11-23 Thread Martin Sebor
GCC currently accepts the declaration of f0 below but ignores the attribute. On aarch64 (and I presume on other targets with a default function alignment greater than 1), GCC rejects f1 with an error, even though it accepts -falign-functions=1 without as much as a warning. Clang, on the other ha

ICEs in print_operand() of the rs6000 backend with invalid input assembly

2018-11-23 Thread Arseny Solokha
Hi, I've found recently that rs6000 and powerpcspe backends can easily trip over various gcc_unreachable()'s and gcc_assert()'s in their respective copies of print_operand() when provided with some invalid assembly (i.e. assembly written for other architectures). For example, when feeding gcc/te
