C++ (Cpp) LLVMPrintModuleToString Examples

Example #1

File: ac_llvm_util.c Project: chemecse/mesa

void
ac_dump_module(LLVMModuleRef module)
{
	char *str = LLVMPrintModuleToString(module);
	fprintf(stderr, "%s", str);
	LLVMDisposeMessage(str);
}

Example #2

File: calc.c Project: AnachroNia/llvm

static void handle_line(char **tokens, int ntokens) {
  char *name = tokens[0];
  LLVMValueRef param;
  LLVMValueRef res;

  LLVMModuleRef M = LLVMModuleCreateWithName(name);

  LLVMTypeRef I64ty = LLVMInt64Type();
  LLVMTypeRef I64Ptrty = LLVMPointerType(I64ty, 0);
  LLVMTypeRef Fty = LLVMFunctionType(I64ty, &I64Ptrty, 1, 0);

  LLVMValueRef F = LLVMAddFunction(M, name, Fty);
  LLVMBuilderRef builder = LLVMCreateBuilder();
  LLVMPositionBuilderAtEnd(builder, LLVMAppendBasicBlock(F, "entry"));

  LLVMGetParams(F, &param);
  LLVMSetValueName(param, "in");

  res = build_from_tokens(tokens + 1, ntokens - 1, builder, param);
  if (res) {
    char *irstr = LLVMPrintModuleToString(M);
    puts(irstr);
    LLVMDisposeMessage(irstr);
  }

  LLVMDisposeBuilder(builder);

  LLVMDisposeModule(M);
}

Example #3

File: module.c Project: BlueRiverInteractive/llvm

int module_dump(bool Lazy, bool New) {
  LLVMModuleRef M = load_module(Lazy, New);

  char *irstr = LLVMPrintModuleToString(M);
  puts(irstr);
  LLVMDisposeMessage(irstr);

  LLVMDisposeModule(M);

  return 0;
}

Example #4

File: llvm-fib.c Project: qeedquan/misc_utilities

	int n = argc > 1 ? atol(argv[1]) : 24;

	LLVMInitializeNativeTarget();

	LLVMModuleRef M = LLVMModuleCreateWithNameInContext("test", Context);

	// We are about to create the "fib" function:
	LLVMValueRef FibF = CreateFibFunction(M, Context);

	// Now we going to create JIT
	LLVMExecutionEngineRef EE;
