c++ - Generating function pointers in LLVM -

-

I am writing my first LLVM sample. I am trying to create a small LLMV module that takes the name of the function and gives an indicator for it. The problem is that I do not know how to generate Function Points in LLVM. I got a function object by calling getDeclaration (...) . Is there any way that I can get an indication for it?

The function is a globalValue, so this is the pointer by itself, in the meantime, you can use the LVVM's C ++ Use backend to generate C + + API calls, which will reconstruct the IR, which you are feeding in LL. For example, feed the following code in the following: 

  zero foo (int (* times) (int)); Int factor (int x); Int main (int argc, char ** argv) {foo (factorial); }   
 Ensure that you have the "Show LLVM C + API code" checkbox selected and you will see related LLVM IR and C + + API calls, which will redo it.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

I'm trying to create a predefined key after checking the manual and I wrote it: Db.execute ("create table" Table 2 (id, integer primary key, somedata integer) "db.execute" (table creation table 2 does not exist (name text, maintain reference (id) ") and found this: sqlite 3.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
