Hi cloud,

Extracted from the gprof manual (which was not included in Nios II 1.0, but it is in 1.0 SP1 and beyond).

"In addition to the -pg and -g options, older versions of GCC required you to specify the -a option when compiling in order to instrument it to perform basic-block counting. Newer versions do not require this option and will not accept it; basic-block counting is always enabled when -pg is on."
