...ementptr into casts and pointer > arithmetic. This is something else I would not recommend. The X86 "simple" instruction selector is not really simple anymore, so it's not a good model to follow for how to emit GEP instructions in a straight-forward way. Try taking a look at the emitGEPOperation method (line 3211) of revision 175 of X86/InstSelectSimple.cpp though. This version is from before the various address optimizations were implemented.

Hello, I'm having problems with the following LLVM instruction %tmp.0.i = call int (sbyte*, ...)* %printf( sbyte* getelementptr ([11 x sbyte]* %.str_1, long 0, ...... The first argument in function call, sbyte* getelementptr ([11 x sbyte]* %.str_1..... appears to be ConstantExpression*, and my backend does not support ConstantExpression yet. I probable can implement
