5- If you write a test for matching a single DAG opcode or intrinsic, it should
6  go in a file called {opcode_name,intrinsic_name}.ll (e.g. fadd.ll)
7
8- If you write a test that matches several DAG opcodes and checks for a single
9  ISA instruction, then that test should go in a file called {ISA_name}.ll (e.g.
10  bfi_int.ll
11
12- For all other tests, use your best judgement for organizing tests and naming
13  the files.

19- Use dash '-' and not underscore '_' to separate words in file names, unless
20  the file is named after a DAG opcode or ISA instruction that has an
21  underscore '_' in its name.
