; Assemble/link:
;   ../utils/mcpu-as -o argc-argv.o argc-argv.s
;   ../utils/mcpu-ld -o argc-argv --stack-size=4K argc-argv.o

; Run:
;   ../utils/mcpu-run \

;     -- \
;     argc-argv --help -x
;
; Guest argv is:
;   argv[0] = "argc-argv"
;   argv[1] = "--help"
;   argv[2] = "-x"
;
; The example prints argc, argv[1][2] ('h') and argv[2][1] ('x') as integers.
; Expected output:
