513403d420 Revert team and thread changes for COMPAT_MODE (hrev52010 & hrev52011).
This reverts commit c558f9c8fe.
This reverts commit 44f24718b1.
This reverts commit a69cb33030.
This reverts commit 951182620e.

There have been multiple reports that these changes break mounting NTFS partitions
(on all systems, see #14204), and shutting down (on certain systems, see #12405.)
Until they can be fixed, they are being backed out.

44f24718b1 kernel/x86_64: add compatibility source files to the build.
* add x86 versions of fnsave frstor.
* add missing declaration for elf32_resolve_symbol().

How-to build a x86_64/x86 bootstrap build:
mkdir generated_bootstrap; cd generated_bootstrap
../configure --bootstrap /dir/to/haikuporter/haikuporter /dir/to/haikuports.cross \
  /dir/to/haikuports --build-cross-tools x86_64 /dir/to/buildtools --build-cross-tools x86 -j8 --use-gcc-pipe
jam -q -sHAIKU_PORTER_EXTRA_OPTIONS="-j8 --sourceforge-mirror=freefr --no-source-packages" @bootstrap-raw

a553e95d85 kernel: support elf32 on x86_64.
* define ELF32_COMPAT to enable ELF32 macros.
* add a flag ELF_LOAD_USER_IMAGE_TEST_EXECUTABLE to only check the format.
It will be used by load_image_internal() to check which mode to use when
loading an image.
* in arch_elf_relocate_rel(), switch to elf_addr instead of addr_t, which
would be the wrong size for elf32 on x86_64.
* the ELF compat loader reuses the relevant parts of elf.cpp and arch_elf.cpp,
excluding for instance load_kernel_add_on() or dump functions.

75c31ae28d system: Build using public elf.h header
Reduce duplication of code by

* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
  together

3b802628b8 Support ELF64 in the kernel.
This has been done by adding typedefs in elf_common.h to the correct ELF
structures for the architecture, and changing all Elf32_* uses to those
types. I don't know whether image loading works as I cannot test it yet,
there may be some 64-bit safety issues around. However, symbol lookup for
the kernel is working correctly.

f6a3444449 Added x86_64 ELF64 relocation functions for the bootloader. All that's left to do now is handle the 64-bit load address properly. 2012-06-24 19:22:33 +01:00

f124497815 Added an ELF64 version of preloaded_image.
* There is now 2 structures, preloaded_elf32_image and preloaded_elf64_image,
  which both inherit from preloaded_image.
* For now I've just hardcoded in use of preloaded_elf32_image, but the
  bootloader ELF code will shortly be converted to use templates which use
  the appropriate structure. The kernel will be changed later when I add
  ELF64 support to it.
* All kernel_args data is now compatible between 32-bit and 64-bit kernels.

c07db2ec3f * elf_find_symbol(): Skip undefined symbols and symbols with the wrong binding.
* Implemented missing handling of symbolically linked images and of weak
  symbols.

9bf61a0ecc * Added GNU style ELF symbol versioning support in the kernel, too.
* Fixed memory leak in insert_preloaded_image() in error case.

6a1e04b121 Symbol resolution functions in the kernel: Removed the unused parameter
allowing optional prepending of a string to the symbol names.

80f5469291 * struct vnode is an opaque type now, removed void* where it was used incorrectly.
* Minor cleanup.

c14a34a65f * Improved kernel ELF loader (and made it more similar to the one from the boot
loader): it now supports holes between segments, and accepts any segment order.
* Renamed elf.c to elf.cpp and fixed warnings.
* Renamed elf_image_info::dynamic_ptr and eheader to dynamic_section and elf_header.
* Some cleanup.
