Things to improve in r2
=======================
* focus in single arch (rock allover) mips, ppc64 or arm? imho iphone-arm
* Enhace code analysis
- calculate multiple execution paths to give branch prediction results
- get/set register status of the vm
- analyze from various parent functions and resolve ranged values
- a ranged value can be:
- ut64 from, to
- restrict : %2 (module)
- ...
To think
--------
* Ranged value:
- ut64 from, to
- restrict : %2 (module)
* Add support for aout binaries?
* eprintf should be modified to log into a file
- eprintf_open() -- start log to file
- eprintf_close() -- stop log to file
Questions
=========
* Only use uppercase KMG for Kilo,Mega,Giga in r_num? - 'g' is for double
* radare2.c:217 . find name for maxfilesize to hash
* r_list_foreach_prev is buggy, review and remove..

Refactoring
===========
-----------
* move r_th into r_util
* Merge javasm code (asm, bin -> shlr)
* Rename r_hashtable -> r_ht
* Remove/deprecate libr/vm
- Make ht64.c include ht.c
* Review the r_flags api
* Add pipe_to_buffer..not only file descriptors
@ -290,29 +279,30 @@ Refactoring
- find/use more common cases for char* or &int maps
- automatic callbacks for most common usecases
* Merge r_socket inside r_util ?
* Is RCore->block and blocksize a RBuf ? refactor!11
* Discuss missing r_core_sysenv_update in core/file.c:33
* Add RLog API.. pipeable to disk and stderr..also hookable ..cool for ui (partially done)
* Move disasm loop into r_print (r_print should depend on r_asm)
- thats hard :)
* Redesign core/disasm.c to provide a pluggable api
* Move 'r_syscall_t' stuff into r_debug (sync r_core)
* Implement r_bind api to link multiple pointers
core->asm = r_bind_set (core->asm->bind, r_asm_new ());
* Find a better name for r_buf_fread (really?)
* Review r_io and r_reg API
* semi-ok state (R_TRUFAE), implement r_errno and r_errstr in r_util?
- useful in r_sys_mkdir ?
* Finish and import the spp's getopt owns implementation in r_util (like in p9)
To wipe:
========
To wipe
-------
- Move manpages from man/ to binr/*/? (harder to maintain?)
- Move the content of libr/*/TODO here
- linestyle?? for disassembly lines
- remove libr/vm and libr/db
- imho we should not implement this:
- Implement BLOCK in r_core_sysenv_begin|end ()
* Deprecate CiU (remove) those APIs and dependencies!
- big-ssl.c big-gmp.c ...
- implement GMP in util/big.c
