Brian Carlstrom7940e442013-07-12 13:46:57 -07001785 //
1786 // To get this all correct, we go through several steps.
1787 //
Jeff Hao436183f2016-01-12 16:36:50 -08001788 // 1. We prepare offsets for all data in the oat files and calculate
Vladimir Markof4da6752014-08-01 19:04:18 +01001789 // the oat data size and code size. During this stage, we also set
1790 // oat code offsets in methods for use by the image writer.
Brian Carlstrom7940e442013-07-12 13:46:57 -07001791 //
Jeff Hao436183f2016-01-12 16:36:50 -08001792 // 2. We prepare offsets for the objects in the images and calculate
1793 // the image sizes.
Vladimir Markof4da6752014-08-01 19:04:18 +01001794 //
Jeff Hao436183f2016-01-12 16:36:50 -08001795 // 3. We create the oat files. Originally this was just our own proprietary
Vladimir Markof4da6752014-08-01 19:04:18 +01001796 // file but now it is contained within an ELF dynamic object (aka an .so
Jeff Hao436183f2016-01-12 16:36:50 -08001797 // file). Since we know the image sizes and oat data sizes and code sizes we
Vladimir Markof4da6752014-08-01 19:04:18 +01001798 // can prepare the ELF headers and we then know the ELF memory segment
1799 // layout and we can now resolve all references. The compiler provides
1800 // LinkerPatch information in each CompiledMethod and we resolve these,
1801 // using the layout information and image object locations provided by
1802 // image writer, as we're writing the method code.
1803 //
Jeff Hao436183f2016-01-12 16:36:50 -08001804 // 4. We create the image files. They need to know where the oat files
1805 // will be loaded after itself. Originally oat files were simply
1806 // memory mapped so we could predict where their contents were based
1807 // on the file size. Now that they are ELF files, we need to inspect
1808 // the ELF files to understand the in memory segment layout including
Vladimir Markof4da6752014-08-01 19:04:18 +01001809 // where the oat header is located within.
1810 // TODO: We could just remember this information from step 3.
Brian Carlstrom7940e442013-07-12 13:46:57 -07001811 //
Vladimir Markof4da6752014-08-01 19:04:18 +01001812 // 5. We fixup the ELF program headers so that dlopen will try to
Brian Carlstrom7940e442013-07-12 13:46:57 -07001813 // load the .so at the desired location at runtime by offsetting the
1814 // Elf32_Phdr.p_vaddr values by the desired base address.
Vladimir Markof4da6752014-08-01 19:04:18 +01001815 // TODO: Do this in step 3. We already know the layout there.
