Bug ID: 40007
Summary: Cannot run strip-all on a relocatable object
Product: tools
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: llvm-objcopy

I'm not really sure why you would do this, but GNU objcopy allows it, and I
think it's "just" a temporal dependency issue in llvm-objcopy (there's no
fundamental reason why you shouldn't be able to). If you try to run strip-all
on an object file with at least one relocation in it target a symbol, you get
an error when it tries to strip the symbol, despite us also planning to strip
the relocations.
Example:
extern int bar;
int main(){
return bar;
}
$ llvm-objcopy -S bar.o foo.o
error: not stripping symbol 'bar' because it is named in a relocation.
