Regarding compiling a program with different options
 

I am suing RHEL.I have a small C/Cpp program and I am trying the possible combinations during compilations that I can use.I want to see the output of all the options I am trying to redirect this output in a file but I dont get to see the output in the file.This is what I am trying to do

My c program is named as prog4.cpp

now I am compiling this program with multiple options of g++ such as -Wall,-fno-inline etc etc I want to see the individual output for these options but I cannot see it in the file that I am redirecting the output to.Can someone help?

Thanks Regards,
Ajit

Sorry the word is using and not suing

It's not possible to see the effects of those options in something other than the compiled file. You can direct GCC to compile the C file and stop at the assembly. By comparing the assembly files, you might see the effects of the options.

If that's what you're after, try this command

Hi Modprob.I tried your suggestion but I dont see much difference in the two asm files that I run with with the options.

Thanks for letting me know the -S option though:)

The fno-inline option is a hint to GCC. It can choose to ignore it.
