Mixed source / Assembly listing

Altera_Forum · ‎06-23-2005

Is this possible, so I can get a fair idea on how the code for this is distributed?

Hi Jason,

Use the objdump -S option.

Hi Scott.

It looks as though the -S option is already used:

"OBJDUMP = nios2-elf-objdump -D -S -x"

in the file C:\altera\kits\nios2_v5\components\altera_nios2\HAL\src\component.mk

I suspect I need to turn on a "debug info" option, or to specify the "source dirs"

By adding the -l option (line numbers), i.e.

"OBJDUMP = nios2-elf-objdump -D -S -x -l"

...I was able to produce a list of line numbers in a few code sections only:

e.g. C:\altera\kits\nios2_v5\bin\nios2-gnutools\src\gcc\gcc\config\nios2\lib2-divmod.c

- not the HAL nor project source files.

So there must be something really simple I've overlooked......

Ahaa!

The mixed source appears in the DEBUG configuration, but not in the RELEASE.

Hi Jason,

Yep, you need to make sure the -g option is passed to the compiler.

And don't strip the elf ;-)

Hey,Scott!

I have a question maybe seems silly to you.You said mixed listing can be seen by using the objdump -s option,

but where can I set this option in NiosII IDE?

Thx

Hi yancharles,

> where can I set this option in NiosII IDE?

I don't think I can help you with this one since I'm an old command-line fogey ;-)

and I always run objdump from the shell.

You should however enable debugging information using the '-g' option. You can do this

in your project properties under C/C++ Build, Debug level.
