Hi All,
For a while now I have been wondering if the gcc linker frontend cares knowing
about -g or -O flags. Let's say I have an object file a.o and I want to link it
into an executable a.out using gcc I can just say:
gcc a.o
But I can also use debug or optimization flags:
gcc -g a.o
gcc -O2 a.o
....
Does the gcc linker frontend care about these flags or are they simply ignored?
Is it generally advisable to use some consistent set of -g/-O flags during
linkage compared to what was used during compilation of the objects (what if the
objects where compiled with different options)?
Thanks for any advice!
-Gerhard
