static library unresolved symbols compiled using gcc

0 votes

I'm inspecting a static library with nm, and I see that the tool provides me with the unresolved symbols of a file foo.o even though those symbols are defined in file zoo.o and both are included in the static library (ar rcs libmy.a zoo.o foo.o).

How can I ask nm to resolve these symbols if they can be found within the files of the archive and just report me about the other not resolved?

As far as I know there is no way to do that directly.

You can do it indirectly by doing

ld -r -o foo.o --whole-archive foo.a
nm -u foo.o

When I was building GCC, I found out that stage1-gcc is not compiled with optimization (such as -O2). So the compilation of stage2 is very slow. Is this intended or not? If not, did I made some mistakes in configure options and caused this?

I wonder how one could get the compiler to generate the "movdqu" instruction, since the vector extensions always seem to assume that everything will be aligned to 16 byte.
I tried using a packed struct and this dint help much. Of course one can always resort to inline assembly but this should not be necessary

Compile with:

gcc -O2 -S -msse2 testvecs.c

Using built-in specs.
