hi, Duncan, thank you for your reply; instruction "i->getOperand(0)->dump()" may print the %4 in the screen, but how can i store it in a variable like char * oprand="%4" ? -- View this message in context: http://llvm.1065342.n5.nabble.com/get-the-identifies-of-the-unnamed-temporaries-from-the-instruction-of-LLVM-IR-tp56572p56588.html Sent from the LLVM - Dev mailing list archive at Nabble.com.

Hello, I am having some trouble matching patterns in targetinstructioninfo.td file with the CodeGen expectation. Could anybody please help? Here is the example: I want to emit instruction for adding 2 different kind of oprands. Basically i want to mix register types when I define the instruction for add,sub etc I define the instruction TargetInstruction.td as follows: class MyInst <opcode op,subopcode subop, dag outs, dag ins, string asmstr,list<dag> pattern> Instruction { let Namespce = "MyNameSp...

...is not the right distribution list. Question: - I am having hard time lowering ADD instructions for different purposes. Basically, I want to have different machine instruction for pointer addition vs scalar addition. I am having hard time mapping LLVM add to my machine add instruction based on the oprand types. Here is the sample code: void myFunction( int* src, int* dst, int i ) { dst[i] = src[i]; i = i + 4; return; } I want to get this translate to my machine code as following: shl R1028, R1026, 2 add_pointer R1029, R1024, R1028 // incrementing the src pointer load R1030, R1029 add_p...

hi, Duncan: thanks for your patience. i have tried it. using instuction: errs()<<i->getOperand(0); but it prints the address: someting like 0x1139700; i checked the defination of getOperand() is Value* getOperand( unsigned int i); so is there someting i missed? -- View this message in context:
