**Best reviewed with "Hide whitespace" When looking into https://github.com/JuliaLang/julia/pull/61292, I tried to use `versioninfo` to get the JIT’s cpu target. I found out that even though it shares parentheses with “ORCJIT”, the displayed cpu is always just the host CPU. Then I fell into the confusing and undocumented output of `versioninfo` rabbit hole trying to improve it and this is the result of that. Once I have a better idea about which changes are/aren't welcome, I’ll edit the docstring to be more explicit about what each item is. May be worth reviewing per-commit as I've tried to separate each change This PR: * Changes “GB” and “MB” to “GiB” and “MiB” when reporting memory information. * Moves the detected host cpu llvm target to be with the CPU instead of in the LLVM section. I changed this because the previous way implied it was the JIT target cpu. They usually match, but they may not if julia was launched with the `-C` flag * The build commit has been moved down into “Build Information” * Refactors the “Build Information” section. It will now always be shown, and the GC julia was built with was moved from the “Platform Information” section. * Adds the target cpu and triple that the base system image was built with when `verbose=true`. ~This adds a new Sys.BASE_SYSIMG_TARGET constant variable because calling `sysimage_target` from InteractiveUtils returns “sysimage”. Hidden behind `verbose` flag~ Edit: `sysimage_target` behaviour seems to have been fixed so the implementation now uses it. * LLVM section now reports the JIT target CPU where the host CPU use to be. ~This expands/uses API that was added by @gbaraldi for GPUCompiler in #49858.~ (edit: I found a way to do it using existing code) * The triple on the OS line is now the JIT target triple (same implementations worries as above), and the build machine triple (MACHINE) is now reported in the verbose-only sysimage line in “Build Information”. This is probably more relevant on macOS, where the triple includes the kernel version, but I find it [confusing](https://github.com/JuliaGPU/Metal.jl/issues/179#issuecomment-1555068273) to show the build kernel version when reporting the current OS.
