21 Non-comprehensive list of changes in this release
22 =================================================
27 * ld.lld now has typo suggestions for flags:
28 ``$ ld.lld --call-shared`` now prints
29 ``unknown argument '--call-shared', did you mean '--call_shared'``.
36 * Like the ELF driver, lld-link now has typo suggestions for flags.
38 * lld-link now correctly reports duplicate symbol errors for obj files
39 that were compiled with /Gy.
41 * lld-link now correctly reports duplicate symbol errors when several res
42 input files define resources with the same type, name, and language.
43 This can be demoted to a warning using ``/force:multipleres``.
45 * Having more than two ``/natvis:`` now works correctly; it used to not
46 work for larger binaries before.
48 * Undefined symbols are now printed only in demangled form. Pass
49 ``/demangle:no`` to see raw symbol names instead.
51 * The following flags have been added: ``/functionpadmin``, ``/swaprun:``,
54 * Several speed and memory usage improvements.
61 * lld now correctly links crtend.o as the last object file, handling
62 terminators for the sections such as .eh_frame properly, fixing
63 DWARF exception handling with libgcc and gcc's crtend.o.
