説明

The 1.0 (or 1.1) compiler emitted the compilation flags into the source map. We added this for hypothetical tooling scenarios, where browser tools could trigger a simple recompilation of a file discovered by a source map, in the case where it was live edited.

This is not a high priority as those scenarios aren't currently planned, but perhaps it would be a simple port of work already done.

調査方針
This issue involves porting an old feature from TypeScript 1.0/1.1 that emitted compilation flags into source maps. The contributor should search the git history for the original implementation, likely in the compiler source files such as src/compiler/. The current source map generation code is in src/compiler/emitter.ts or similar. The maintainer's comment says it might be a simple port, but details are sparse. The contributor should first understand how compilation flags are stored and then modify the source map emitter to include them, ensuring backward compatibility.
