<#
.SYNOPSIS
Build script for the perfaware project (8086 simulator + tooling).
.DESCRIPTION
Compiles the canonical source tree into a Win32 console executable
using clang and lld-link. No CRT (/ENTRY:main, /NODEFAULTLIB).
Prerequisites:
- clang on PATH (LLVM install)
- lld-link.exe on PATH (LLVM install)
- Windows SDK (for kernel32.lib, user32.lib, gdi32.lib)
Build artifacts land in <root>/build/. The script is not
incremental -- every invocation recompiles every source file.
