Don't use dlopen() for libebl modules

2019-08-29T11:30:30+00:00

Currently, architecture-specific code for libebl exists in separate
libebl_$ARCH.so libraries which libebl loads with dlopen() at runtime.
This makes it impossible to have standalone, statically-linked binaries
which use libdwfl if they depend on any architecture-specific
functionality. Additionally, when these libraries cannot be found, the
failure modes are non-obvious. So, let's get rid of libebl_$arch.so and
move it all into libdw.so/libdw.a, which simplifies things considerably.

Add PIC and non-PIC variants of libcpu and libebl

2019-08-28T19:45:26+00:00

Currently, libcpu and libebl are always compiled as PIC. An upcoming
change will add the objects from libcpu.a and libebl.a to libdw.a, which
should not be PIC unless configured that way. So, make libcpu.a and
libebl.a non-PIC and add libcpu_pic.a and libebl_pic.a.

libcpu: merge libcpu_{i386,x86_64,bpf} into one library

2019-08-28T19:29:18+00:00

In preparation for combining the libebl backend modules, combine all of
the libcpu backends into libcpu.a.

libdwelf: Add dwelf_elf_e_machine_string and use it in readelf.

2019-07-10T12:08:33+00:00

To print eh human readable description of the ELF e_machine header field
we used the ebl name. But this is not set for most EM constants. Introduce
a new function dwelf_elf_e_machine_string that does work for all known
EM values. Use that in eu-readelf to print a string representation of the
e_machine value.

Since this was the only usage of ebl->name, remove that from struct ebl.

Also add a testcase that makes sure dwelf_elf_e_machine_string works for
all EM values in the libelf/elf.h header so we will immediately notice
when a new value appears.

backends: riscv_cfi.c had a bad BACKEND define.

2019-04-14T20:40:53+00:00

BACKEND should have been defined as riscv_ (not aarch64_).

s390: elflint should check if _GLOBAL_OFFSET_TABLE_ points to .got.

2019-02-15T13:39:57+00:00

The _GLOBAL_OFFSET_TABLE_ symbol might point to the DT_PLTGOT,
which is in the .got section, even if the symbol itself is
associated with the .got.plt section.

RISC-V: Add untested 32-bit core file support.

2019-01-13T10:08:42+00:00

Adds 32-bit support exactly the same way that the sparc backend handles
32- and 64-bit core file support.  The 64-bit core file support was tested
and still works same as before.

RISC-V: Add initial return value location support.

2019-01-10T12:25:33+00:00

Started with the aarch64 support and modified it for RISC-V.  The
flattened structure support hasn't been written yet, but the rest of
it should be correct for the LP64D ABI.  We have potentially 6 different
ABIs to support, so this requires checking elf header flags in riscv_init
when setting the hook.
