When writing MachineFunction unit tests, I find it quite tedious to verify correctness in C++. I would like to use FileCheck in UnitTests because FileCheck is extremely convenient/robust to verify correctness. In order to do so, I moved most of FileCheck’s implementation into a header (Support/FileCheck.h) and updated FileCheck.cpp to use this.
I ran into this while writing some target agnostic Legalization code in GISel where it’s not possible or extremely inconvenient to use llc.
What do others think of this? I would think there might be non GISel uses for FileCheck in unit tests, but I’m not sure.
Here’s a quick patch for this (https://reviews.llvm.org/D48850 <https://reviews.llvm.org/D48850>)
