2 + New executable formats
3 + Read list of libraries needed
4 + Read list of undefined symbols in executables
5 + Read list of exported symbols in libraries
6 + Read debugging info from executables/libraries
7 * Automatically update list of syscalls?
8 * Improve documentation
9 * Improve -e/-x options (regexp?)
11 * Improve C++ name demangling
12 * Display different argument types
13 * Update /etc/ltrace.conf
14 * More architectures, cleaner way to port
15 * More operating systems (solaris?)
16 * Option -I (inter-library calls)
17 * Modify ARGTYPE_STRING[0-5] types so that they don't stop displaying chars when '\0' is seen
18 * Get rid of EVENT_ARCH_SYSCALL and EVENT_ARCH_SYSRET
19 * Cleaner way to use breakpoints:
20 + BP is placed in the PLT
21 + When control hits there:
22 - write down return address
23 - change return address with another one (handled by ltrace)
25 - change the process' PC to be in the correct place,
26 without removing breakpoint
27 + When control hits one of our return addresses:
29 - change PC to the right place
30 * To be able to work with processes sharing memory, we must:
31 + ptrace() every single thread
32 + place breakpoints only in places where the process control can continue
33 without having to remove it
34 * List source dependencies in Makefile
35 * Create different ltrace processes to trace different children
36 * After a clone(), syscalls may be seen as sysrets in s390 (see trace.c:syscall_p())
