# Module Benchmark_accumulator

    module Benchmark_accumulator: sig .. end

The point of `Benchmark_accumulator` is to provide a global place where inline benchmarking macros can register themselves. Once registered here, the benchmarks are retrieved and analyzed using `Core_bench`.

This module holds the registered benchmarks in a global hashtable indexed by library name. We care about the registered benchmarks if and only if the library is being used in a `inline_benchmarks_runner.exe`. To avoid building this hashtable in cases where we will not use it, this module peeks into the commandline args of the running program to decide if the benchmarks should be registered or not.

    module Current_libname: sig .. end

    module Entry: sig .. end

    val add_benchmarks_flag : bool

`add_benchmarks_flag` returns true if the benchmarks should be added to the hashtable

    val lookup_lib : libname:string -> Entry.t list

`lookup_lib` returns all the benchmarks from the specified library

    val add_bench : name:string ->
           code:string ->
           filename:string ->
           type_conv_path:string ->
           line:int ->
           startpos:int -> endpos:int -> Entry.test_spec -> unit

`add_bench` registers benchmarks with the global hashtable maintained in `pa_bench_lib`. This is meant to be called by the code generated for the BENCH and BENCH_INDEXED macros

    val add_bench_module : name:string ->
           code:string ->
           type_conv_path:string ->
           filename:string ->
           line:int -> startpos:int -> endpos:int -> (unit -> unit) -> unit

`add_bench_module` adds a bench module name to the benchmarks. This is called by BENCH_MODULE macro
