Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
Here, attempting to use a non-class type in a qualified name (T::foo) results in a deduction failure for f<int> because int has no nested type named foo, but the program is well-formed because a valid function remains in the set of candidate functions.
Visual Studio 2017 15.8 (MSVC 19.15) Standard Library and later supports all C++17 library features except for "Elementary String Conversions" and referring to C99 instead of C11. "Elementary String Conversions" is added in Visual Studio 2019 16.4 [ 54 ]
Clang becomes default compiler for Android [52] (and later only compiler supported by Android NDK [53]). 13 March 2017 Clang 4.0.0 released: 26 July 2017: Clang becomes default compiler in OpenBSD 6.2 on amd64/i386. [54] 7 September 2017 Clang 5.0.0 released: 19 January 2018: Clang becomes default compiler in OpenBSD 6.3 on arm. [55] 5 March 2018
Visual Studio .NET preprocessor reference; Pre-defined C/C++ Compiler Macros project: lists "various pre-defined compiler macros that can be used to identify standards, compilers, operating systems, hardware architectures, and even basic run-time libraries at compile-time"
The Visual Studio and Windows SDK include the program undname which prints the C-style function prototype for a given mangled name. On Microsoft Windows, the Intel compiler [2] and Clang [3] uses the Visual C++ name mangling for compatibility.
.NET Compiler Platform, also known by its codename Roslyn, [2] is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft. [ 3 ] The project notably includes self-hosting versions of the C# and VB.NET compilers – compilers written in the languages themselves.
