libelf: Add ELF compression types and defines to libelf.h for older glibc.

2016-01-14T13:26:22+00:00

Older glibc elf.h might not define the new ELF compression defines and
types. If not just define them in libelf.h directly to make the libelf
headers work on older glibc systems.

Also include a testcase to check the libelf headers build against the
system elf.h.

libelf: Make elf_strptr index correctly into compressed section data.

2016-01-06T13:27:10+00:00

elf_strptr indexes into the section data. This is defined as index into
the uncompressed data of the section. If the section is compressed make
sure the uncompressed data is available, but don't really decompress the
section header (elf_getdata will still return compressed data).

libelf: Add elf32_getchdr, elf64_getchdr and gelf_getchdr.

2016-01-06T13:27:10+00:00

Elf_Data of a compressed section has type ELF_T_CHDR. This type can be
xlated to the file or memory representation. This will make sure the Chdr
is in the correct endianess. The compressed data following the Chdr isn't
translated.

Disable clang for arm64 where local __thread is used.

2015-11-20T21:52:13+00:00

clang/llvm for aarch64 generates relocation references
to local symbols and that is not supported by Android
dynamic linker.

Enable clang compiler for some modules.

2015-11-16T22:07:12+00:00

* libdwelf, libebl, libelf can compile cleanly with clang now.
* libdw and libdwfl still have some nested functions only compiled by gcc.
