Program compiled with -ggdb3 switch run slow

[riteshtaksali]

Hi

I am using the g++ compiler to compile the program on centos 5.

I would like to know
Whether the program compiled with -gdb3 or -g option run slows?
like g++ -ggdb3 SampleProgram.cpp run slow in compare to compiled without -g option

Thanks
Ritesh

Any comments on this?

Well, I googled:

ggdb3 slow

and discovered that, yes, folks expect the compiler to produce slower code when the -ggdb3 option is used.

Exactly why, I don't know. Perhaps there are certain optimizations which are ordinarily compiled into the code but which are omitted if you're going to use gdb, because if they were included, then the debugging experience would be misleading and confusing.

Just a guess.
