Hi!Based on c#15, we should probably consider this a bit of a band-aid, right? Thus we'll install the band-aid, but keep the PR open pending a better solution for handling of input_location, correct?
As discussed in the PR, this is a safer variant of a fix for 4.8, where input_location during most optimization passes is set to DECL_SOURCE_LOCATION (current_function_decl) and various parts of the gimplifier e.g. during force_gimple_operand* may end up setting gimple_location to that. For 4.9, we should revert this and set input_location to UNKNOWN_LOCATION for the optimizers.
Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk.
