Edited lld/ELF/Options.td to cdsort as well CDSort function reordering outperforms the existing default heuristic ( hfsort/C^3) in terms of the performance of generated binaries while being (almost) as fast. Thus, the suggestion is to change the default. The speedup is up to 1.5% perf for large front-end binaries, and can be moderate/neutral for "small" benchmarks. High-level **perf impact** on two selected binaries: clang-10 binary (built with LTO+AutoFDO/CSSPGO): wins on top of C^3 in [0.3%..0.8%] rocksDB-8 binary (built with LTO+CSSPGO): wins on top of C^3 in [0.8%..1.5%] More detailed measurements on the clang binary is at [here](https://reviews.llvm.org/D152834#4445042)
lld Documentation ================= The lld documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. We currently use the 'nature' theme and a Beaker inspired structure. See sphinx_intro.rst for more details.
