Subject: [Tinycc-devel] bounds checking
I just committed a large patch that fix a lot of bounds checking
problems.
I tested the bounds checking code now works on x86_64 and i386 on linux
and windows.
The test/tests2 directory can now be tested with -b enabled.
There are a lot of changes (not complete):
- split up bcheck.c from libtcc1.a because I now use dl_sym to redirect
malloc and friends.
This was needed because the malloc_hooks are not thread safe.
When compiling with -b now the pthread and dl library are also
included.
- Rewrote bcheck.c library to fix a lot of small problems.
- Add mmap/munmap support on linux.
- Updated tcc.1
- Added bound_main_arg to record argv on startup.
- Added support for x86_64 on windows.
- Moved tcc_add_bcheck from tccelf to i386/x86_64 code.
- Added 2 new testcases.
- Fixed a lot of bugs:
- conversion problem code with double/long long.
- in gen_bounded_ptr_add move save_regs to top.
- alloca/vla fixes.
- VT_LLOCAL problems when using bounds checking.
- ...
Regards,
Herman
