Yep. That sounds like llmvpipe. See http://mesa3d.org/llvmpipe.html for details. But note that have "source lines" for jit code is hard: - Some of the LLVM IR we generate comes from TGSI which has no source line info. We could have the info from the GLSL, but that has no source files. . - Some of TGSI doesn't come from GLSL, but rather fixed function. - Some of the LLVM IR doesn't even come from TGSI or any shaders, but its bound state like depth-stencil test, or format conversion. None of that IR has source files. We could use the debug info from the C code that generates the LLVM IR that generates the . In short, we could try to improve things a bit, but JIT code will always be quite different from static C code.

This issue isn't totally just that. LIBGL_ALWAYS_SOFTWARE=true mode does use LLVM doesn't it? And I find profiling information trailing from a perf-foo.map file that seems to correspond to JITted code. So, I think this is still valid for LIBGL_ALWAYS_SOFTWARE=true mode. I was mistaken for unset LIBGL_ALWAYS_SOFTWARE though I think. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://urldefense.proofpoint.com/v2/url?u=http-3A__lists.freedesktop.org_mailman_listinfo_mesa-2Ddev&d=AAIGaQ&c=Sqcl0Ez6M0X8aeM67LKIiDJAXVeAw-YihVMNtXt-uEs&r=zfmBZnnVGHeYde45pMKNnVyzeaZbdIqVLprmZCM2zzE&m=IVw7I-5WEvdqar1LGKpNSi56XoZMlsmzcc5IKTLmvYA&s=iCS5PuoCjw1nnf0AgSWX0cNGwCa1NET5erjzE8lrX8U&e= _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
