@asyync1024 I don't have a computer that resource constrained in usable state. I'll consider switching back after I get a chance to test.

In the meantime, you can set _use_clang=true.

  • _use_clang=true makepkg -sri
  • extra-x86_64-build -- -- _use_clang=true

@xiota Any leads on the performance gap? Have you tried it yourself?

Q9550 @ 3.33GHz, GT 740 GDDR3 4GB, 4GB Dual Channel 800 MT/s RAM.

It's pretty bad but seems decent for emulating a DS. It handles Azahar (3DS emulator) easily at 5x native, 25 fps or so.

Here are the results of comparing the melonDS binary produced by both compilers: GCC vs Clang (fps) 1x native: 45 vs 60 6x native: 35 vs 60

Almost a 2x slowdown. Performed on "MegaMan Zero Collection", which has no 3D elements.

@asyync1024 GCC is known to be slower than Clang in some cases. What hardware are you running on?

Hey! I had compiled with GCC yesterday as you know, but I am experiencing slow-down in OpenGL (Classic) and OpenGL (Compute Shader) renderers. Software "seems" to work fine.

Can you confirm if the significant slowdown appears on your end too? Clang seems to produce a working, non-slow binary. Sorry for not testing before.

Hey! GCC 16 now successfully builds melonDS! So there is no need to keep Clang anymore, thanks.

Per the discussion here using clang to link will solve the problem. i've tested. Please add these to the build options array:

-DCMAKE_CXX_COMPILER=clang++
    -DCMAKE_C_COMPILER=clang

the executable fails to link at the end. ...
