2 Using -opt-bisect-limit to debug optimization errors
11 The -opt-bisect-limit option provides a way to disable all optimization passes
19 check the opt-bisect limit before performing optimizations.  Passes which
25 The -opt-bisect-limit option can be used with any tool, including front ends
39 The -opt-bisect-limit command line option can be passed directly to tools such
44   <tool name> [other options] -opt-bisect-limit=<limit>
50 opt-bisect-limit.  All optimizations with a higher index value will be skipped.
52 In order to use the -opt-bisect-limit option with a driver that provides a

62 The -opt-bisect-limit option may also be applied to link-time optimizations by
64 following syntax will set a bisect limit for LTO transformations:

71   clang -flto -Wl,-plugin-opt,-opt-bisect-limit=256 my_file.o my_other_file.o
