Georgii Rymar 19edd675c6 [LLD][ELF] - Make compression level be dependent on -On. ... Currently LLD always use zlib compression level 6. This patch changes it to use 1 for -O0, -O1 and 6 for -O2. It fixes https://bugs.llvm.org/show_bug.cgi?id=44089. There was also a thread in llvm-dev on this topic: https://lists.llvm.org/pipermail/llvm-dev/2018-August/125020.html Here is a table with results of building clang mentioned there: ``` Level Time Size 0 0m17.128s 2045081496 Z_NO_COMPRESSION 1 0m31.471s 922618584 Z_BEST_SPEED 2 0m32.659s 903642376 3 0m36.749s 890805856 4 0m41.532s 876697184 5 0m48.383s 862778576 6 1m3.176s 855251640 Z_DEFAULT_COMPRESSION 7 1m15.335s 853755920 8 2m0.561s 852497560 9 2m33.972s 852397408 Z_BEST_COMPRESSION ``` It shows that it is probably not reasonable to use values greater than 6.
