| name | split-asm |
| description | Split BenchmarkDotNet assembly markdown files into individual files per benchmark method using splitasm. Use to break one big assembly code file per benchmark into one file per benchmark method. |
Usage
/split-asm [<ResultsPath>]
Arguments
$ARGUMENTS - Optional path to the BenchmarkDotNet results directory. Defaults to BenchmarkDotNet.Artifacts/results in the current repository.
Instructions
Run splitasm to break down BenchmarkDotNet assembly markdown files into a single file per benchmark method. This enables using file diffs to compare how code changes affect disassembler output.
Parse the arguments: the optional first argument is the path to the results directory.
If a path is specified, execute:
dotnet run --project C:/repo/splitasm/splitasm -- <ResultsPath>
If no path is specified, default to the standard BenchmarkDotNet output location:
dotnet run --project C:/repo/splitasm/splitasm -- BenchmarkDotNet.Artifacts/results
The tool produces:
- Individual assembly files - one markdown file per benchmarked method containing its assembly code
- A summary file listing disassembled code size in bytes for each benchmarked method
Output is organized hierarchically by target benchmark, then by target framework.
Prerequisites
The splitasm repository should be cloned to C:/repo/splitasm. If not available, clone from https://github.com/bitfaster/splitasm:
cd C:/repo && git clone https://github.com/bitfaster/splitasm.git
