The c55x_plus decoder shipped with two private string helpers in
utils.c:
strcat_dup(s1, s2, n_free) - allocate s1+s2 and optionally free
inputs, with a bitmask controlling
which of s1/s2 are released
get_hex_str(n) - format the low 8 bits of n as a
two-character lowercase hex string
Both have direct equivalents in rz_util:
strcat_dup(s, lit, 1) -> rz_str_append(s, lit)
strcat_dup(lit, s, 2) -> rz_str_prepend(s, lit)
strcat_dup(s1, s2, 3) -> rz_str_append_owned(s1, s2)
strcat_dup(s1, s2, 1) where
s2 is also owned and freed
manually right afterwards -> rz_str_append_owned(s1, s2)
get_hex_str(n) -> rz_str_newf("%02x", n & 0xff)
This commit converts all 56 strcat_dup call sites in
c55plus_decode.c and decode_funcs.c plus the single get_hex_str
site, then deletes utils.c and utils.h entirely.
While here, replace several local sprintf-into-stack-buffer +
rz_str_dup patterns with direct rz_str_newf calls:
- get_AR_regs_class1: was malloc(50) + sprintf per case, now a
single rz_str_newf per case returning the result directly.
The function is reduced from 34 lines to 14.
- get_AR_regs_class2: same pattern, reduced from 130 lines to
79 with no allocation needed at the top.
- get_token_decoded case 40/48, 70/72/80, 41/73: sprintf into
a 512-byte stack buffer then rz_str_dup -> single rz_str_newf.
- decode_funcs.c case 2 of get_status_regs_and_bits: was
calloc(50) + sprintf, now rz_str_newf.
The 512-byte stack buffer 'buff_aux' in get_token_decoded becomes
unused and is removed.
C55PLUS_DEBUG, the only useful symbol that used to live in utils.h,
moves to ins.h (which all c55x_plus translation units transitively
include). ins.h gains a direct <rz_util.h> include so the rest of
the headers don't need to pull it in indirectly.
No behavioural change. Full c55x_plus test regression passes:
asm/tms320_c55x+_32 104/104, analysis/tms320.c55x+_32 45/45,
parity against TI dis55.exe v4.3.6 on the 13-source testbins corpus
remains 140/140.

Rizin
Rizin is a reverse engineering framework, born as a fork of the radare2, with a focus on usability, features and cleanliness.
Rizin is portable and it can be used to analyze binaries, disassemble code, debug programs, as a forensic tool, as a scriptable command-line hexadecimal editor able to open disk files, and much more!
To learn more on Rizin you may want to read the official Rizin book.
How to install
Look at install instructions on our web page.
How to build
Use meson to compile and install Rizin. Please make sure to get an updated
meson (e.g. get it with pip install meson if your system does not provide
one that is at least version 0.55.0).
Clone this repository:
$ git clone https://github.com/rizinorg/rizin
Then compile and install with:
$ meson setup build
$ meson compile -C build
$ sudo meson install -C build
Now you can use rizin:
$ rizin
-- Thank you for using rizin. Have a nice night!
[0x00000000]>
To uninstall rizin, execute sudo ninja -C build uninstall.
Please have a look at BUILDING.md for more information about building Rizin.
Contributing
We very much welcome any kind of contributions, from typos, to documentation, to refactoring, up to completely new features you may think of. Before contributing, we would like you to read the file CONTRIBUTING.md, so that we can all be on the same page.
Tests
Look at test/README.md.

Tools
Apart from the main tool rizin, there are also other tools tailored for specific purposes and
useful for shell scripting or as separate standalone tools:
rz-bin- provides all kind of information about binary formatsrz-ar- list and extract members from static archives (.a and .lib)rz-asm- a command-line assembler and disassemblersrz-diff- a tool to compare two binaries as raw data or analyzed executablesrz-hash- allows to calculate different hashes or even encrypt datarz-gg- a small "eggs" code generator useful for exploitation purposesrz-find- binary analog offindtool, allowing to search patterns and bit masksrz-sign- tool to create, convert and parse FLIRT signaturesrz-ax- a calculator and number format converterrz-run- a tool that allows to specify running environment and arguments for debugged file
Scripting
We provide a way to interact with Rizin from Python, Haskell, OCaml, Ruby, Rust, and Go languages through rzpipe. Other languages although not currently supported could be easily added.
