@rem Script to build LuaJIT with the PS5 SDK.
@rem Donated to the public domain.
@rem
@rem Open a "Visual Studio .NET Command Prompt" (64 bit host compiler)
@rem or "VS20xx x64 Native Tools Command Prompt".
@rem
@rem Then cd to this directory and run this script.
@rem
@rem Recommended invocation:
@rem
@rem ps5build        release build, amalgamated, 64-bit GC
@rem ps5build debug    debug build, amalgamated, 64-bit GC
@rem
@rem Additional command-line options (not generally recommended):
@rem
@rem gc32 (before debug)    32-bit GC
@rem noamalg (after debug)  non-amalgamated build
