Defects

• ctors/dtors (or initializers specified by attributes) do not work.
• C++ exceptions do not work. The patch disables generation of CFI (Call Frame Information), because the assembler (of FX10) does not accept pseudo-instructions of CFI.
• Floating-point comparisons by FCMP (generating a result in registers) do not properly generate results on orderedness.

TODO

• Make all LNT tests pass (except for ctors/dtors and exceptions).
• Code cost model.
• Code reciprocals.
• Code 4-SIMD instructions.
• Code masked stores (STFR, STDFR).
• Code element swap of SIMD FMA.
• Code integer SIMD instructions.
• Make the original SPARC V9 work by removing conflicts with the modifications.
