Author: rnk Date: Thu May 11 17:43:02 2017 New Revision: 302835 URL: http://llvm.org/viewvc/llvm-project?rev=302835&view=rev Log: Issue diagnostics when returning FP values on x86_64 without SSE1/2
Avoid using report_fatal_error, because it will ask the user to file a bug. If the user attempts to disable SSE on x86_64 and them use floating point, that's a bug in their code, not a bug in the compiler. This is just a start. There are other ways to crash the backend in this configuration, but they should be updated to follow this pattern.
