| // Notes on the interleaving of creating the image and oat file to |
| // ensure the references between the two are correct. |
| // |
| // Currently we have a memory layout that looks something like this: |
| // |
| // +--------------+ |
| // | image | |
| // +--------------+ |
| // | boot oat | |
| // +--------------+ |
| // | alloc spaces | |
| // +--------------+ |
| // |
| // There are several constraints on the loading of the image and boot.oat. |
| // |
| // 1. The image is expected to be loaded at an absolute address and |
| // contains Objects with absolute pointers within the image. |
| // |
| // 2. There are absolute pointers from Methods in the image to their |
| // code in the oat. |
| // |
| // 3. There are absolute pointers from the code in the oat to Methods |
| // in the image. |
| // |
| // 4. There are absolute pointers from code in the oat to other code |
| // in the oat. |
| // |
| // To get this all correct, we go through several steps. |
| // |
| // 1. We prepare offsets for all data in the oat file 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 image and calculate |
| // the image size. |
| // |
| // 3. We create the oat file. 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 size and oat data size and code size 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 file. It needs to know where the oat file |
| // will be loaded after itself. Originally when oat file was simply |
| // memory mapped so we could predict where its contents were based |
| // on the file size. Now that it is an ELF file, we need to inspect |
| // the ELF file 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. |
| |
| |
| // Write out the generated code part. Calls the OatWriter and ElfBuilder. Also prepares the |
| // ImageWriter, if necessary. |
| // Note: Flushing (and closing) the file is the caller's responsibility, except for the failure |
| // case (when the file will be explicitly erased). |
