Passing by reference means that the memory address of the variable (a pointer to the memory location) is passed to the function. This is unlike passing by value, where the value of a variable is passed on. In the examples, the memory address ofmyAgeis 106. When passingmyAgeto the funct...
Thanks also for the example with the pointer, just a couple of clarifications: 1. what c_loc stands for? We want the C address of the string s, right? 2. why lens must enter in getS with the lenght of 128? to reserve the memory space? (sorry, maybe this is c...
For reference types, only the pointer to the data is copied (four bytes on 32-bit platforms, eight bytes on 64-bit platforms). Therefore, you can pass arguments of type String or Object by value without harming performance. Determination of the Passing Mechanism ...

The C/C++ technique for passing parameters is always the same, regardless of calling convention: All parameters are passed by value, except for arrays, which are translated into the address of the first member. To pass data by reference, pass a pointer to it. ...
C-style arrays (including multidimensional arrays) are passed by reference (EDIT: technically by pointer). Don't worry, I made the same mistake of assuming otherwise once. -Albatross Last edited onAug 18, 2019 at 5:53am Aug 18, 2019 at 6:15am ...

Historically it was documented as being TableGen-only, but that was lost in631bfdb's conversion to using the generated defines. Let's preserve that intent by not allowing it to originate through accidental calls to get(E)VT with a PointerType. If you need to support that, be sure to use...
