2016-01-27compiler: Don't crash on erroneous array return types.Ian Lance Taylor2-1/+3
Another issue with erroneous array types. When an erroneous array type is in a function's signature, particularly the return type, we must guarantee that type is changed into an error type. Otherwise, any operations that work on arrays and slices will crash when applied to the erroneous array return type. Fixes golang/go#12939.

2016-01-26compiler: Avoid knock-on errors with impossibly large types.Ian Lance Taylor2-3/+5
The gofrontend asks the backend compiler for the architecture appropriate size of a given type. For array types, it is possible to construct a type too large to fit on the machine. This patch does two things: 1. When an impossibly large type is encountered, we mark the type as erroneous and later calls to discover the size of that type are short-circuited. 2. When generating the GC symbol data for an impossibly large array of arrays, we avoid generating symbol data as soon as we find an array that is too large to be expressed. Fixes golang/go#12938.
