This is the part that discouraged me since every time I format the SD card I have to reinstall a LOT of files, especially with fighting characters. Now it's automatic :shocked: :joia:

* GPC Compiler: Updated xb1.gph header file to include XB1_SYNC define (BUTTON_21)

Is it possible to discard local variables from discarded functions? Freeing up the static memory.

Example
Code: Select all
main {
 
}
void func() {
  fix32 a[64];
  static fix32 b[64];
  return;
}
Code: Select all
GPC: Variables: Global: 0, Local: 2, Parameters: 0, Pointers: 0, Constants: 0, Labels: 0, Functions: 1, Combos: 0
GPC: Memory usage: Static: 256 bytes (25.00%), Dynamic: 256 bytes (25.00%)
GPC: Second-pass started.
GPC: Unreferenced: func, a, b
GPC: Garbage collection started.
GPC: Discarded: func, a*, b* (* static memory still allocated)
I understand why static variables should be allocated, however, I don't see the purpose of still allocating them from discarded functions. Seeing as they would never be used.

I know by utilizing the preprocessor you can choose to include or to omit the function completely by doing something like this
Code: Select all
#define func
#include "my_header.gph"
main {
  func();
}
my_header.gph
Code: Select all
#pragma once
 
#ifdef func
#undef func
#define func func
void func() {
  fix32 a[64];
  static fix32 b[64];
  return;
}
#endif
But it would be nice to simply include the header, and not worry about defining any functions that I plan to use.

I downloaded the Gtuner IV 1.8 beta to solve share/touch button on paddles issue for Xbox Elite 2 controller.

Installed the direct download application, but my Titan Two seems to be stuck on 1.73 firmware. The problem is that I couldn't locate the "Gtuner.cfg" file on my iMac. Went to my Gtuner IV.app to show package content, found the Gtuner.exe but not the .cfg. Also could not find Gtuner under Application Support with hidden files shown either. Could someone help me out?

I"m assuming adding the [Advanced] beta_tester=true code will solve the issue.

Thanks

Yes, you are correct. On Mac the Gtuner.cfg is here:

Macintosh HD⁩ ▸ ⁨Users⁩ ▸ ⁨(UserName)⁩ ▸ ⁨Library⁩ ▸ ⁨Application Support⁩ ▸ ⁨Gtuner⁩

You have to show hidden files first Shift + Command + >

Thank you DontAtMe for your suggestions.

The Gtuner 1.08 Beta Rev3 released today has significant improvements on the garbage collection procedures. However, static variables are still allocated. The addressing of static variables are determined when generation the symbol table (first-step), to complicate the addressing is memory aligned depending on the data type, as such a simple offsetting to remove the unused variable will not work. To proper get hid of unused static variables would be need re-run all compiler procedures from beginning. I did not discarded this option yet, however, would prefer find a more elegant/optimized way.
