---|---|---|---|---|
| ||||
Hello, About ASDF ------------- ASDF [3] is a cache oriented string based JSON representation. Besides, it is a convenient Json Library for D that gets out of your way. ASDF is specially geared towards transforming high volumes of JSON dataframes, either to new JSON Objects or to custom data types. Release Notes -------------- v0.1.5-beta0 [2] release comes with the new parser that significantly improves performance. Benchmarks -------------- See also the benchmarks [1] against sajson, one of the fastest C++ JSON parser implementations. Bug fixes ------------- - Recursion failure [stack overflow] #65 [4] Please help to test this pre-release! ASDF is maintained by Tamedia Digital. Best regards, Ilya Yaroshenko [1] https://github.com/tamediadigital/asdf/tree/master/benchmarks/sajson [2] https://github.com/tamediadigital/asdf/releases/tag/v0.1.4-beta0 [3] https://github.com/tamediadigital/asdf [4] https://github.com/tamediadigital/asdf/issues/65 |

AFAIK, ldc translates dmd's -O option to llvm's -O3.

sajson loops are manually unrolled already. Very aggressive optimisation makes no sense and may unroll loops additionally and slowdown the program.

Any reason clang++ is only -O2, not -O{3,s,z}?
