can I profile on basic block level for nios

Hi, kerri,

I have read the document mnl_niossft.pdf, and the following are excerpted from the pdf file. There are no option for basic block profiling.

I use: man nios-elf-gcc and it shows that -a option is availble for nios-elf-gcc. But I failed in using this option when compiling applications.

Yes, I am using cygwin version. can I install the software in linux operationg system? I just installed all the software and the gnu tools are installed automatically. There are some functionality constrains when installing the gnu tools in cygwin?

We bought the developement board from altera company. However, for research purpose, We need to manipulate nios softcore which niosii is not very suitable.

do you work in altera company? I have may questions about nios system.

nios-elf-gprof nios-elf-gprof produces an execution profile of a C program.

Usage

nios-elf-gprof [option(s)] [objfile] gmon.out

Options

f For more information about gprof, see

http://sources.redhat.com/binutils/docs-2....info/index.html (http://sources.redhat.com/binutils/docs-2.12/gprof.info/index.html)

Table 16. nios-elf-gprof Options

Option Description

-C This option causes gprof to print a tally of functions

and the number of times each function was called.

-q The call graph shows for each function; a tally of which

function called nios-elf-gprof and which other

functions nios-elf-gpof called. The call graph also

gives an estimate of how much time was spent in the

subroutines of each function.

This data suggests places where functions can be

eliminated because of the amount of time they take.

-p The flat profile shows the amount of time a program

spent in each function and the number of times each

function was called. The flat profile provides concise

data about which functions burn most of the cycles.

-A The annotated source listing is a copy of the program¡¯s

source code labeled with the number of times each

line of the program was executed.
