Author: Dave Airlie <airlied@redhat.com> In order to implement indirect sampler loads, we don't want to match on a VGPR load but an SGPR one for constants, as we cannot feed VGPRs to the sampler only SGPRs. this should be applicable for llvm 3.7 as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@243294 91177308-0d34-0410-b5e6-96231b3b80d8

| How to organize the lit tests |
+==============================================================================+
- If you write a test for matching a single DAG opcode or intrinsic, it should
go in a file called {opcode_name,intrinsic_name}.ll (e.g. fadd.ll)
- If you write a test that matches several DAG opcodes and checks for a single
ISA instruction, then that test should go in a file called {ISA_name}.ll (e.g.
bfi_int.ll
- For all other tests, use your best judgement for organizing tests and naming
the files.
+==============================================================================+
| Naming conventions |
+==============================================================================+
- Use dash '-' and not underscore '_' to separate words in file names, unless
the file is named after a DAG opcode or ISA instruction that has an
underscore '_' in its name.
