973e48744b Removed guard on memcpy_s call to memcpy. All the Undefined Behavior has been removed. The CRYPTOPP_ASSERT remains to guard the use of the functions, as does Clang/GCC Undefined Behavior sanitizer 2015-08-03 19:20:27 -04:00

b44546be11 Revert "Hid inline assembly behind a macro". The MEMORY_BARRIER code is OK, and the use of inline assembly code is OK to tame the optimizer is OK; but its confusing because the interactions are not readily apparent. 2015-08-01 19:00:31 -04:00

264018e8ec Suppressed "sign comparison" warning under GCC and Clang 2015-07-30 09:14:43 -04:00
Jeffrey Walton
33e6a62c5e Reverted to previous SafeConvert code. Its not as efficient as it could be, but it is darn sure correct. Self-tests for the verification to follow 2015-07-30 08:38:28 -04:00
Jeffrey Walton
414b673706 Added test for T1 is signed 2015-07-29 22:37:36 -04:00
Jeffrey Walton
2936447d05 Updated IntToString and SafeConvert to squash the "signed/unsigned" warnings once and for all. Removed the specializations that caused more trouble than they were worth. (If all platforms offered size_t and ssizeT the same way, specializations would have been the preferred solution 2015-07-29 06:33:41 -04:00

ef318d5423 Fixed compiler errors on Apple due to cross product of {C++03,C++11} x {libc++, libstdc++}. It included bringing in the correct <memory> in <stdcpp.h>, and then only including <stdcpp.h> when <memory> was needed. 2015-07-27 16:01:55 -04:00

c42947e19b Rearranged includes for consistency after testing 2015-07-27 13:03:18 -04:00

30b706316b Cleared "signed/unsigned" warning introduced by 1997c21b37 under GCC. The ultimate fix is to guard the std::streamsize specialization to ensure Microsoft compilers don't see it 2015-07-26 13:56:45 -04:00
Jeffrey Walton
1997c21b37 Cleared "explicit specialization has already been defined" under MSVC and Visual Studio 2015 2015-07-26 11:27:36 -04:00

Jeffrey Walton
b2d9be1b80 Cleared "unused variable" warning when using CRYPTOPP_STATIC_ASSERT under GCC. The "__attribute__ ((unused)" was present in GCC 2.95, so it will be available for the GCC's we support. Non-GCC's will get the non-decorated assert 2015-07-23 12:30:13 -04:00

ac0f94c23a Removed branch from rotlVariable. The mask ensures it stays well defined 2015-07-23 04:06:10 -04:00
Jeffrey Walton
1303f4bdcc Cutover to CRYPTOPP_ASSERT in misc.h. Posix's behavior of "let's crash the program by raising SIGABRT" in Debug builds has got to be one of the most questionable decisions in the history of computing. The new behavior: if there's a SIGTRAP handler somewhere, then the handler will be invoked. Some platforms, like Apple and Microsoft, provide a default SIGTRAP handler. If there's no SIGTRAP handler, then the program will crash just like it raised a SIGABRT. In this case, there's no effective change in behavior 2015-07-23 03:39:13 -04:00

e6300f52e2 Removed template specializations for Clang using preprocessor for rotFixed due to LLVM Bug 24226. Removed asserts from __rlwinm because the mask ensures the operation is well defined (see the comments in ppc_intrinsics.h) 2015-07-23 01:53:45 -04:00

8cef820ac8 Cleared UBsan error based on undefined shift. Tightened behaviors based on offline conversation with Wei and Denis. One shift error remains due to use of rotVariable by Cast. The UB will be cleared shortly, when specializations using GCC assembler is checked in 2015-07-17 22:21:01 -04:00
Jeffrey Walton
5f299d76a0 Cleared UBsan error on non-null pointers being used with memcpy and memmove from library functions memcpy_s and memmove_s 2015-07-17 21:09:42 -04:00

8386b3f139 Guarded COUNTOF macro. Thanks to Graham Bull for the suggestion 2015-07-05 17:53:42 -04:00
Jeffrey Walton
f2379159f8 Added COUNTOF to misc.h to count elements in an array (fails on pointers). Moved CRYPTOPP_UNUSED to misc.h 2015-07-03 15:40:44 -04:00

457eaeaf23 Static analysis showed the unsigned int y is truncated to an unsigned char via _rotr16. It does not appear to be a problem with the library, but it may be a problem for users. The assert will alert in Debug builds (but not Release builds) 2015-06-29 08:38:38 -04:00
Jeffrey Walton
a14a5696e1 Added GCC_DIAGNOSTIC_AWARE to help suppress some warnings on contemporary compilers. The macro was needed to help with managing old compilers, like GCC 4.2.1, present on OpenBSD 2015-06-29 02:09:02 -04:00
