<div>
<pre>llvm-nm doesn't returns nothing useful from files compiled with LTO.
If we have the file test.c containing
'''
char a[10];
char b[20];
char c[30];
'''
and run `$CC -flto -c test.c -o test.o` the result of `llvm-nm -P test.o`
turns out to be the following
'''
a C ---------------- 0
b C ---------------- 0
c C ---------------- 0
'''
I do understand address/offset information being unavailable, but shouldn't
this output encode at least something concerning each symbol's value/size?</pre>
