commit 872820898d7d3cb237b130efe33f3dc1768499d4
3+
4+
Removed lots of debug message() commands
5+
that were just for debugging meson.build.

commit f4219c32811ac50e61c478ccf3d89061843bfac6
10+
11+
Added note about zstd (in common use
12+
in Linux before 2020) and libsztd-dev

commit 778be0d1075eb133dc177483197786ea9314c02d
23+
24+
We delete
25+
four message() meson commands
26+
that were for debugging our use
27+
of meson. These four are no longer needed.

commit 7eb45d468c05282be8ef7495136a62834df0e9e9
32+
33+
If e_shoff is zero we immediately declare there
34+
is nothing here for DWARF and DW_DLV_NO_ENTRY
35+
is returned. Consistent with the generic Elf ABI
36+
documentation.
37+
No further checking for Elf corruption
38+
or anything else is done.

commit c0cfba34ec80996426b5be2523f6447a2c9b7b39
43+
44+
Revized the new logic on segments/sections
45+
for clarity and to catch corrupted object files
46+
earlier.

commit f83ca35f17336f8723aebacc167793d71c0f723e
51+
52+
We now recognize a Mach-o object file (as opposed
53+
to a DSYM) and just treating that slighly differently
54+
lets libdwarf show the DWARF content.
55+
(Because, unlike DSYM, an object file has both
56+
executable code and DWARF data and a slight difference
57+
in how certain names appear)

commit 3f2098ff28255c186a84899b2cc10678b65a02a9
64+
65+
Reversed the order of two lines to preserve
66+
a test result. I don't have any TI binaries
67+
and don't expect to, so the TI extension
68+
overlapping DW_TAG_lo_user is a beter choice
69+
than DW_TAG_TI_far_type to show.

commit 4f4e51dfb234bad27d9adb9338555e578ca4f340
91+
92+
Documenting the new command to turn off access
93+
to decompression libraries for a build of libdwarf.
94+
95+
meson
96+
To build a libdwarf that does not refer to or link with
97+
decompression libraries zstd or zlib, add the meson
98+
option "-Ddecompression=false"
99+
100+
configure
101+
As of version 0.9.1 the configure option
102+
"--disable-decompression" tells the build to compile
103+
libdwarf and dwarfdump with no reference to the zlib or
104+
zstd libraries.
105+
106+
cmake
107+
To turn off linking with or using zlib or zstd libraries
108+
or headers there is an option to cmake add the cmake
109+
option DENABLE_DECOMPRESSION=NO.

commit dafb9bc45af0b918ff80ab668617f73c9f5778d7
116+
117+
With cmake option -DENABLE_DECOMPRESSION=NO
118+
libdwarf will build without any reference
119+
to zlib.h or zstd.h or the respective libraries.

commit 82214ba96ba9c6a02c5584fd1dd8803f71760bed
125+
126+
Now passing --disable-decompression to configure
127+
turns off access to libz and zstd,
128+
which is of use to some not expecting
129+
to see compressed sections and missing
130+
libz or zstd.

commit 89604291e005b1b81efee9a11742edb6443cbedb
135+
136+
Now we define -Ddecompression=YES
137+
as the default and library builders can
138+
pass -Ddecompression=NO to the meson
139+
command to turn off decompression and
140+
avoid any dependency on libz or zstd.
141+
142+
Fixed a bug which would result in
143+
a compile failure referencing includes
144+
for libz.h and zstd.h if one had neither.
145+
Doing set10('LIBZ_H',false) in meson
146+
has the wrong effect, as LIBZ_H gets defined 0
147+
so #ifdef LIBZ_H
148+
finds LIBZ_H is defined.

commit 20e6efcbde6ba8fd964cde62c0e4c5b3ee3088b9
156+
157+
ifdefs for zstd.h and zlib.h were written in a
158+
non-obvious way. Now in standard libdwarf form for clarity.
