TODO:
* Create a machine pass for performing dual-pipeline scheduling specifically
- for CellSPU, handle inserting branch prediction instructions.
+ for CellSPU, and insert branch prediction instructions as needed.
* i32 instructions:
* sign and zero extension: done
* addition: done
* subtraction: needed
- * multiplication: work-in-progress
+ * multiplication: done
* i128 support:
- * zero extension: done
+ * zero extension, any extension: done
* sign extension: needed
* arithmetic operators (add, sub, mul, div): needed
+ * logical operations (and, or, shl, srl, sra, xor, nor, nand): needed
-* Double floating point support
+ * or: done
- This was started. "What's missing?" to be filled in.
+* f64 support
+
+ * Comparison operators:
+ SETOEQ unimplemented
+ SETOGT unimplemented
+ SETOGE unimplemented
+ SETOLT unimplemented
+ SETOLE unimplemented
+ SETONE unimplemented
+ SETO done (lowered)
+ SETUO done (lowered)
+ SETUEQ unimplemented
+ SETUGT unimplemented
+ SETUGE unimplemented
+ SETULT unimplemented
+ SETULE unimplemented
+ SETUNE unimplemented
+
+* LLVM vector suport
+
+ * VSETCC needs to be implemented. It's pretty straightforward to code, but
+ needs implementation.
* Intrinsics
- Lots of progress. "What's missing/incomplete?" to be filled in.
+ * spu.h instrinsics added but not tested. Need to have an operational
+ llvm-spu-gcc in order to write a unit test harness.
