Pull Request Overview

This PR standardizes the SConscript group name to lwProcess, refactors error handling for the vDSO build step, and removes two legacy architecture-specific scripts.

• Refactor vDSO build: consolidate clean logic into one command, wrap subprocess.run in a try/except, and report failures.
• Rename all DefineGroup calls from vDSO/lwP to lwProcess.
• Delete components/lwp/arch/x86/i386/SConscript and components/lwp/arch/risc-v/rv64/SConscript.

• [nitpick] Renaming the vDSO group to lwProcess may conflict with the main LWP group and obscure the vDSO target. Consider using a distinct name like lwProcess-vdso for clarity.

group = DefineGroup('lwProcess', src, depend = ['RT_USING_SMART','RT_USING_VDSO'], CPPPATH = CPPPATH)

Avoid using a bare except: which also catches system-exiting exceptions. Catch specific errors (e.g., except subprocess.CalledProcessError as e:) to prevent unintended behavior.

Suggested change

	# generic error handle
	except :
	print('exec command: "%s" failed.' % ' '.join(command))
	exit(1)
	except subprocess.CalledProcessError as e:
	print(f'Command "{e.cmd}" failed with return code {e.returncode}.')
	exit(1)
	except FileNotFoundError as e:
	print(f'Command not found: {e}. Please ensure "scons" is installed and in your PATH.')
	exit(1)

[Copilot]

When using check=True, subprocess.run will raise on non-zero exits, so this manual returncode check is redundant. Consider removing it or use check=False if you need to handle exit codes explicitly.

Suggested change

	if result.returncode == 0:
	print("Command executed successfully")
	else:
	print("Command failed with exit code:", result.returncode)
	exit(1)
	print("Command executed successfully")
