Introduce `jl_image_buf_t` to represent the in-memory details of an unparsed system image and clean-up several global variables and split loading logic in staticdata.c so that we get (almost) everything we need from the sysimage handle at once. This allows sysimage loading to be separated into three phases: 1. Lookup the raw sysimage buffer as a `jl_image_buf_t` 2. For .so sysimages, parse the sysimage and initialize JIT targets, etc. 3. Finally load the sysimage into a `jl_image_t` Care was taken to preserve the existing behavior of calling `jl_set_sysimg_so` to configure the sysimage before initializing Julia, although this is likely to be next on the chopping block in a follow-up. Dependent on #57523.
This adds `jl_pgcstack_default_func` to allow an uninitialized runtime to make it into `jl_autoinit_and_adopt_thread` The init changes themselves are left to #57498 --------- Co-authored-by: Cody Tapscott <[email protected]>
…lier (#58231) This changes the order of initialization slightly. The goal is to be able to initialize executables and share libraries without having to explicitly call init functions. This still doesn't address the thread safety
This accidentally diverged when #58141 was merged without adjusting the test to match (these tests shouldn't be re-implementing the `juliac` link step anyway, but they currently do) Unfortunately, this hid a bug where `jl_pathname_for_handle` does not understand the main executable.

The Pkg failure seems to be the same on the backport branch: https://buildkite.com/julialang/julia-release-1-dot-12/builds/109#0196a1f6-bbf9-418b-ad5a-9e9fa118e4a0/885-929 |
