julia 运行时的初始化——以 `println("hello world!")` 为例

综合讨论区 心得体会

这个是对 julia devdoc Julia 运行时的初始化 的补充笔记。
较为详细的给出了文档中涉及到的函数调用点、被调用函数源代码所在的位置。

（主要是整理了一堆链接，不保存一下浪费了

代码基于 julia 1.6.3，以 cygwin+mingw64+x86_64 环境的调试版编译产物为例

main()

到下一节的调用链：mainCRTStartup → jl_load_repl → repl_entrypoint → julia_init

mainCRTStartup @ cli/loader_exe.c:26

jl_load_repl @ cli/loader_lib.c:183

repl_entrypoint @ src/jlapi.c:668

julia_init()

到下一节的调用链：julia_init → return → true_main

julia_init @ src/task.c:309 →
_julia_init @ src/init.c:631

true_main()

到下一节的调用链：true_main → jl_apply → Base._start

true_main @ src/jlapi.c:549

Base._start

Base._start @ base/client.jl:477

Core.eval

到下一节的调用链：Core.eval → return to repl_entrypoint → jl_atexit_hook

Core.eval @ base/boot.jl:360
