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

...variable. But be careful, you may need to change also the references to those variables. Have a look to the method GlobalVariable::use_begin and use_end. They give you references to the users of the global variable.

hello guys, recently, i successfully get and modify global variable by execution engine. the functions i used are listed here: int m=1; EE->updateGlobalMapping(p->M->getGlobalVariable("x",true),&m); EE->recompileAndRelinkFunction(EntryFn); x is the global variable in the module. but how to modify the local variable in the module? -- View this message in context:

hello Óscar Fuentes, thanks for your reply, if i use the API provided by parser.h and the program *.ll i parsed contains local variable, i can get a module have local variable without defines it first. i think that module is a structure like AST(i am not sure whether i was right), this must be a traversal method. am i right or do i misunderstand something? -- View this message in context:

hi Óscar Fuentes, i am new to llvm, so i still have several questions. thanks for you help. (1)what is SSA form(static single assignment)? (2)how to traverse the basic blocks? if the module is gained by parser, what will the basic blocks contain? i will be on the line, thank you very much -- View this message in context:

hi Óscar Fuentes , thanks for your reply, but there are still a lot of concepts i don't understand. there seems to be some document to guide you but hard to understand. can you show me some basic and easy to learn document or websites? thank you -- View this message in context:

hi Sam: thank you for your reply. but i have another question about this 'select' instruction. i think that in LLVM IR, i can use a branch and two seperate assignments to replace 'select' instruction(am i right?). so is there any compiling option to aviod generate 'select' instruction? -- View this message in context:

hi Eduardo, thanks for your attention, i checked the iterator, but i didn't see any fucntion can return or modify the main memory address of a global variable inside the module. can you provide some reference code or program can achieve this? thank you very much -- View this message in context:

recently, i use LLVM API to write a program to read *.ll and excute it automatically. Further more, i want to change some global variables inside a module. i tried some functions provided by Module.h and ExecutionEngine.h but none were seemed to match my need. did someone have the experience or some advices? thank you ;) -- View this message in context:

hi Eduardo, i got what you did, but it seemed that you modified the Global Variable list, deleted Global Variable and created new one and added it to the list. I don't know whether i got it right and for more details, can you get the main memory address of the Global Variable? or did the iterator provide method to get this? thank you very much -- View this message in context:

hi guys, i use clang to compile a program with datatype uint, but i get errors saying " use of undeclared identifier 'uint'; did you mean 'int'?
