|
|
//
|
|
// +--------------+
|
|
// | images |
|
|
// +--------------+
|
|
// | oat files |
|
|
// +--------------+
|
|
// | alloc spaces |
|
|
// +--------------+
|
|
//
|
|
// There are several constraints on the loading of the images and oat files.
|
|
//
|
|
// 1. The images are expected to be loaded at an absolute address and
|
|
// contain Objects with absolute pointers within the images.
|
|
//
|
|
// 2. There are absolute pointers from Methods in the images to their
|
|
// code in the oat files.
|
|
//
|
|
// 3. There are absolute pointers from the code in the oat files to Methods
|
|
// in the images.
|
|
//
|
|
// 4. There are absolute pointers from code in the oat files to other code
|
|
// in the oat files.
|
|
//
|
|
// To get this all correct, we go through several steps.
|
|
//
|
|
// 1. We prepare offsets for all data in the oat files and calculate
|
|
// the oat data size and code size. During this stage, we also set
|
|
// oat code offsets in methods for use by the image writer.
|
|
//
|
|
// 2. We prepare offsets for the objects in the images and calculate
|
|
// the image sizes.
|
|
//
|
|
// 3. We create the oat files. Originally this was just our own proprietary
|
|
// file but now it is contained within an ELF dynamic object (aka an .so
|
|
// file). Since we know the image sizes and oat data sizes and code sizes we
|
|
// can prepare the ELF headers and we then know the ELF memory segment
|
|
// layout and we can now resolve all references. The compiler provides
|
|
// LinkerPatch information in each CompiledMethod and we resolve these,
|
|
// using the layout information and image object locations provided by
|
|
// image writer, as we're writing the method code.
|
|
//
|
|
// 4. We create the image files. They need to know where the oat files
|
|
// will be loaded after itself. Originally oat files were simply
|
|
// memory mapped so we could predict where their contents were based
|
|
// on the file size. Now that they are ELF files, we need to inspect
|
|
// the ELF files to understand the in memory segment layout including
|
|
// where the oat header is located within.
|
|
// TODO: We could just remember this information from step 3.
|
|
//
|
|
// 5. We fixup the ELF program headers so that dlopen will try to
|
|
// load the .so at the desired location at runtime by offsetting the
|
|
// Elf32_Phdr.p_vaddr values by the desired base address.
|
|
// TODO: Do this in step 3. We already know the layout there.
|
|
//
|
|
// Steps 1.-3. are done by the CreateOatFile() above, steps 4.-5.
|

// are done by the CreateImageFile() below.
