configure: Add new --enable-install-elfh option.

2019-01-31T22:51:17+00:00

We explicitly test (with system-elf-libelf) that our include headers
work with the system elf.h header. But it might be helpful to install
the elf.h file for a private install. Our elf.h header really is just
a copy of the latest glibc elf.h. But it might be newer and include
more constants than the system installed elf.h.

Add a new configure option --enable-install-elfh to install elf.h.
But warn when it is enabled for the default /usr or /usr/local prefix
because it might clash with the glibc/system elf.h header in that case.

Require gawk in maintainer mode

2018-07-05T18:09:30+00:00

gawk is required to build known_dwarf.h, so check for it in configure.ac.

Prepare for 0.172.

2018-06-11T17:02:20+00:00

It has been only 10 days since the previous release and there are
no functional changes compared to 0.171. The speedup of eu-readelf -N
is pretty nice. And ~25 patches fix various bugs (hangs and crashes)
in dealing with bad DWARF5 data. Most have been found by running the
afl fuzzer on eu-readelf and various testcases.

libdwfl: Use process_vm_readv when available.

2018-03-28T14:30:27+00:00

If possible use process_vm_readv to read 4K blocks instead of fetching
each word individually with ptrace. For unwinding this often means we
only have to do one process_vm_readv of the stack instead of dozens of
ptrace calls. There is one 4K cache per process, cleared whenever a
thread is detached.

Use fallthrough attribute.

2018-02-10T02:19:26+00:00

Use __attribute__ ((fallthrough)) to indicate switch case fall through
instead of a comment. This ensures that the fallthrough warning is not
triggered even if the file is pre-processed (hence stripping the
comments) before it is compiled.

The actual fallback implementation is hidden behind a FALLBACK macro in
case the compiler doesn't support it.

Finally, the -Wimplict-fallthrough warning was upgraded to only allow
the attribute to satisfy it; a comment alone is no longer sufficient.

lib: Remove md5 and sha1 implementations.

2017-10-20T11:51:02+00:00

Only the testcase md5-sha1-test used them. So also remove that testcase.

Make sure packed structs follow the gcc memory layout

2017-09-20T19:40:31+00:00

gcc defaults to using struct layouts that follow the native conventions,
even if __attribute__((packed)) is given. In order to get the layout we
expect, we need to tell gcc to always use the gcc struct layout, at
least for packed structs. To do this, we can use the gcc_struct
attribute.

This is important, not only for porting to windows, but also potentially
for other platforms, as the bugs resulting from struct layout
differences are rather subtle and hard to find.
