Usage: ocamloptp <options> <files> options are: -P [afilmt] Profile constructs specified by argument (default fm): a Everything f Function calls and method calls i if ... then ... else l while and for loops m match ... with t try ... with -a Build a library -absname Show absolute filenames in error messages -annot Save information in <filename>.annot -bin-annot Save typedtree in <filename>.cmt -inline-branch-factor <n>|<round>=<n>[,...] Estimate the probability of a branch being cold as 1/(1+n) (used for inlining) (default 0.10) -c Compile only (do not link) -cc <command> Use <command> as the C compiler and linker -cclib <opt> Pass option <opt> to the C linker -ccopt <opt> Pass option <opt> to the C compiler and linker -clambda-checks Instrument clambda code with closure and field access checks (for debugging the compiler) -Oclassic Make inlining decisions at function definition time rather than at the call site (replicates previous behaviour of the compiler) -color {auto|always|never} Enable or disable colors in compiler messages The following settings are supported: auto use heuristics to enable colors only if supported always enable colors never disable colors The default setting is 'auto', and the current heuristic checks that the TERM environment variable exists and is not empty or "dumb", and that isatty(stderr) holds. -compact Optimize code size rather than speed -config Print configuration values and exit -dtypes (deprecated) same as -annot -for-pack <ident> Generate code that can later be `packed' with ocamlopt -pack -o <ident>.cmx -g Record debugging information for exception backtrace -i Print inferred interface -I <dir> Add <dir> to the list of include directories -impl <file> Compile <file> as a .ml file -inline <n>|<round>=<n>[,...] Aggressiveness of inlining (default 1.25, higher numbers mean more aggressive) -inline-toplevel <n>|<round>=<n>[,...] Aggressiveness of inlining at toplevel (higher numbers mean more aggressive) -inline-alloc-cost <n>|<round>=<n>[,...] The cost of not removing an allocation during inlining (default 7, higher numbers more costly) -inline-branch-cost <n>|<round>=<n>[,...] The cost of not removing a conditional during inlining (default 5, higher numbers more costly) -inline-call-cost <n>|<round>=<n>[,...] The cost of not removing a call during inlining (default 5, higher numbers more costly) -inline-prim-cost <n>|<round>=<n>[,...] The cost of not removing a primitive during inlining (default 3, higher numbers more costly) -inline-indirect-cost <n>|<round>=<n>[,...] The cost of not removing an indirect call during inlining (default 4, higher numbers more costly) -inline-lifting-benefit <n>|<round>=<n>[,...] The benefit of lifting definitions to toplevel during inlining (default 1300, higher numbers more beneficial) -inlining-report Emit `.<round>.inlining' file(s) (one per round) showing the inliner's decisions -intf <file> Compile <file> as a .mli file -intf-suffix <string> Suffix for interface files (default: .mli) -keep-docs Keep documentation strings in .cmi files -no-keep-docs Do not keep documentation strings in .cmi files (default) -keep-locs Keep locations in .cmi files -no-keep-locs Do not keep locations in .cmi files (default) -labels Use commuting label mode -linkall Link all modules, even unused ones -inline-max-depth <n>|<round>=<n>[,...] Maximum depth of search for inlining opportunities inside inlined functions (default 1) -alias-deps Do record dependencies for module aliases -no-alias-deps Do not record dependencies for module aliases -app-funct Activate applicative functors -no-app-funct Deactivate applicative functors -no-float-const-prop Deactivate constant propagation for floating-point operations -noassert Do not compile assertion checks -noautolink Do not automatically link C libraries specified in .cmxa files -nodynlink Enable optimizations for code that will not be dynlinked -nolabels Ignore non-optional labels in types -nostdlib Do not add default directory to the list of include directories -no-unbox-free-vars-of-closures Do not unbox variables that will appear inside function closures -no-unbox-specialised-args Do not unbox arguments to which functions have been specialised -o <file> Set output file name to <file> -O2 Apply increased optimization for speed -O3 Apply aggressive optimization for speed (may significantly increase code size and compilation time) -opaque Does not generate cross-module optimization information (reduces necessary recompilation on module change) -open <module> Opens the module <module> before typing -output-obj Output an object file instead of an executable -output-complete-obj Output an object file, including runtime, instead of an executable -p Compile and link with profiling support for "gprof" (not supported on all platforms) -pack Package the given .cmx files into one .cmx -plugin <plugin> Load dynamic plugin <plugin> -pp <command> Pipe sources through preprocessor <command> -ppx <command> Pipe abstract syntax trees through preprocessor <command> -principal Check principality of type inference -no-principal Do not check principality of type inference (default) -rectypes Allow arbitrary recursive types -no-rectypes Do not allow arbitrary recursive types (default) -remove-unused-arguments Remove unused function arguments -rounds <n> Repeat tree optimization and inlining phases this many times (default 1). Rounds are numbered starting from zero. -runtime-variant <str> Use the <str> variant of the run-time system -S Keep intermediate assembly file -safe-string Make strings immutable -shared Produce a dynlinkable plugin -short-paths Shorten paths in types -strict-sequence Left-hand part of a sequence must have type unit -no-strict-sequence Left-hand part of a sequence need not have type unit (default) -strict-formats Reject invalid formats accepted by legacy implementations (Warning: Invalid formats may behave differently from previous OCaml versions, and will become always-rejected in future OCaml versions. You should always use this flag to detect invalid formats so you can fix them.) -no-strict-formats Accept invalid formats accepted by legacy implementations (default) (Warning: Invalid formats may behave differently from previous OCaml versions, and will become always-rejected in future OCaml versions. You should never use this flag and instead fix invalid formats.) -thread Generate code that supports the system threads library -unbox-closures Pass free variables via specialised arguments rather than closures -unbox-closures-factor <n > 0> Scale the size threshold above which unbox-closures will slow down indirect calls rather than duplicating a function (default 10) -inline-max-unroll <n>|<round>=<n>[,...] Unroll recursive functions at most this many times (default 0) -unboxed-types unannotated unboxable types will be unboxed -no-unboxed-types unannotated unboxable types will not be unboxed (default) -unsafe Do not compile bounds checking on array and string access -unsafe-string Make strings mutable (default) -v Print compiler version and location of standard library and exit -verbose Print calls to external commands -version Print version and exit --version Print version and exit -vnum Print version number and exit -w <list> Enable or disable warnings according to <list>: +<spec> enable warnings in <spec> -<spec> disable warnings in <spec> @<spec> enable warnings in <spec> and treat them as errors <spec> can be: <num> a single warning number <num1>..<num2> a range of consecutive warning numbers <letter> a predefined set default setting is "+a-4-6-7-9-27-29-32..39-41..42-44-45-48-50-60" -warn-error <list> Enable or disable error status for warnings according to <list>.
