Also change some options that have different semantics (cause confusion) in llvm-readelf mode:
-s => -S
-t => --symbols
-sd => --section-data
llvm-svn: 359651
The ELF spec says
Symbols with section index SHN_COMMON may appear only in relocatable
objects.
Currently lld can produce file that break that requirement.
llvm-svn: 319473
Common symbols are now represented with a DefinedRegular that points
to a BssSection, even during symbol resolution.
Differential Revision: https://reviews.llvm.org/D39666
llvm-svn: 317447
Currently ld.lld -r allocates space for common symbols, whereas ld.bfd
-r doesn't. As a result the OpenBSD makefile bits for creating libraries
fail as they use ld -X -r to strip local symbols, which results in
duplicate symbol errors because space for the common symbols has been
allocated.
The diff also implements the --define-commons option such that allocation
of commons can be forced even if -r is used.
