Matching Decompilation

The goal is not merely to understand a function. The goal is to reproduce the target machine code under the project's exact compiler, flags, linker and translation-unit conditions.

Success criterion: the project's authoritative comparison reports an exact match.

1. Inspect before editing

Identify:

• architecture, endianness and ABI;
• compiler/toolchain and exact flags;
• build system and authoritative compare command;
• target source/translation unit;
• objdiff/decomp.me configuration;
• existing typedefs, structs and macros;
• nearby already-matching functions.

Do not assume ELF, x86_64, Ninja, or a particular compare command.
