hi, im creating a music application(image below). At the moment im using tcc compiler but im moving across to clang because of the improved compiler warnings. Can anyone please explain and show code so I can use clang's JIT to call functions in my application? Thanks. http://old.nabble.com/file/p29449300/51709341.jpeg -- View this message in context:

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: http://llvm.1065342.n5.nabble.com/how-to-get-and-modify-a-local-variable-s-value-through-executionEngine-tp52446.html Sent from the LLVM - Dev mailing list archive at Na...

I tried what you said, now I get: LLVM ERROR: Program used external function 'yipee' which could not be resolved! Stack dump: 0. Running pass 'X86 Machine Code Emitter' on function '@main' did not even get as far as a breakpoint. Óscar Fuentes wrote: > > gafferuk <gafferuk at gmail.com> writes: > >> Im confused.

gafferuk <gafferuk at gmail.com> writes: > Im confused. The function i wish to call is a return type of int. > Im calling it with int dd = yipee(1); > > What's wrong? Declare the function: int yipee(int); int main() { int dd = yipee(1); return 0; } If that still crashes, put a breakpoint on `yipee' and see if the execution gets there, if the argument is

A local variable does not exists until the function that defines it is executed, so pretending to get and modify it as you do for the global makes no sense.
