Bug ID: 34395
Summary: llvm-nm yields no useful information for files
compiled with lto
Product: tools
Version: 5.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: llvm-nm
Assignee: [email protected]

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?
