we need to handle sdb meson.build file with subprojects. For now I'm
extracting most of its current content here, so that it will be easier
to update sdb later.
* r2pm/meson.build: install r2pm
* meson.build: use system libraries when available
* travis: add fedora-sys to the list of things to test
* bin_nso.c: still include lz4.c when not on meson
* Dockerfile.travis: add required system dependencies to dockerfile
* meson.build: split zip_dep in libzip and zlib dependencies
* shlr/meson.build: zip needs zlib
* meson.build: fix meson build when not on git
* meson.build: make capstone a dependency
* meson.build: make r_magic library optional
* meson.build: capstone include is already in the dependency
* meson.build: use dependencies instead of manual linking + includes
* meson.build: add travis
* flag/meson.build: include sdb dependency
* travis-script: print messages based on install system
* io/meson.build: add sdb as dependency
* syscall/meson.build: missing sdb dependency
* {parse,config}/meson.build: add sdb dependency
* travis.yml: pass INSTALL_SYSTEM var to docker
* {bin/shlr}/meson.build: add sdb_dep to r2java and bin
* install meson and ninja-build in r2-travis docker
* travis.yml: allow meson build to fail for now
* anal/meson.build: add sdb and java dependencies
* egg/meson.build: add sdb dependency
* travis.yml: meson build env should be also in the includes list
* core/meson.build: add java dep
* meson.build: use dependencies also to create main r2 dependency
* rasm2/meson.build: replace link_with with dependencies
* rasm2/meson.build: add sdb as dependency
* meson.builds: convert link_with to dependencies and fix tabs
* travis-script: change meson install prefix and set PKG_CONFIG_PATH
* travis-script: add lib64 to LD_LIBRARY_PATH
* format/elf: extract function to avoid duplicated code
* format/elf: use ut64 to avoid errors in ELF32
Otherwise, while analyzing ELF32, -1 will be interpreted as the unsigned
value 0xffffffff, which is very different from -1 (0xffffffffffffffff).
* format/elf: fix symbols with shndx == SHT_NULL
Symbols with shndx == SHT_NULL should not be listed as symbols but they
should be available when other ELF structures (imports, relocs, etc.)
reference them.
This patch adds those symbols in the symbols_by_ord table but not to the
list of available symbols. Imports/relocs/etc. work by indexing symbols
by symbol index, so they are going to use the symbols_by_ord table and
make everything work.
Moreover, it refactors a bit the relocs function to avoid duplicated
code.
* bin: setimportd/setsymbold should clone the import/symbol
* bin/bin.c: free fields only when sym is not NULL
* format/elf: do not filter out symbols with size == 0 and consider sht_null symbols in shdr too.
* bin/bin.c: create R_STR_DUP macro and use it in _clone functions
* format/elf: when parsing symbols from phdr, stop at first UNK type/bind
* create some R_BIN defines to handle strings related to TYPE and BIND
in RBinSymbols
* format/elf: add a doc
