 STATISTIC (NumLowered, "Number of instructions lowered")
 
Pass * createLowerMissingInstructionsPass (const TTAMachine::Machine &mach)
 
const std::vector< std::string > & llvmFootprints (std::string tceOp)
 

Detailed Description

Convert instruction which are not supported by the machine to function calls.

NOTE: Right now system is limited to replace only those operations, which use only one bitwidth integers for example i1.icmp.i32.i32 cannot be lowered to function call. However i16.mul.i16.i16 works.

Maybe better way would be to take llvm footprints which must be emulated and create function prototype directly for them.
