Currently unimplemented: * cast fp to bool * signed right shift of long by reg Current bugs: * conditional branches assume target is within 32k bytes * large fixed-size allocas not correct, although should be closer to working. Added code in PPCRegisterInfo.cpp to do >16bit subtractions to the stack pointer. Codegen improvements needed: * no alias analysis causes us to generate slow code for Shootout/matrix * setCondInst needs to know branchless versions of seteq/setne/etc * cast elimination pass (uint -> sbyte -> short, kill the byte -> short) Current hacks: * lazy insert of GlobalBaseReg definition at front of first MBB A prime candidate for sabre's "slightly above ISel" passes. * cast code is huge, unwieldy. Should probably be broken up into smaller pieces. * visitLoadInst is getting awfully cluttered as well. Currently failing tests: * Regression * SingleSource `- Benchmarks | `- Shootout-C++ : most programs fail, miscompilations `- UnitTests | `- 2003-05-26-Shorts | `- 2003-07-09-LoadShorts | `- 2004-06-20-StaticBitfieldInt `- C++Catch `- SimpleC++Test `- ConditionalExpr `- casts `- sumarray2d: large alloca miscompiled `- test_indvars * MultiSource |- Applications | `- burg: miscompilation | `- siod: llc bus error | `- hbd: miscompilation | `- d (make_dparser): miscompilation `- Benchmarks `- MallocBench/make: branch target too far
