Amante -a Generate extra code to write profile information for basic blocks, suitable for the analysis program tcov(1). Eventually GNU gprof(1) should be extended to process this data. This switch is compatible with the -a switch of the SunOS 4.x cc -a switch. Note, that gcc -a is only supported on Sun-2,-3 and -4 systems. As I reported before, it does even not work yet (see article <1027@isaak.UUCP>).
