This new mode will allow for the simultaneous activation of a set of options to enhance protection, similar to the flag \"-fhardened\" introduced in GCC 14, which enables options like \"-D_FORTIFY_SOURCE=3 -D_GLIBCXX_ASSERTIONS -ftrivial-auto-var-init=zero -fPIE -pie -Wl,-z,relro,-z,now -fstack-protector-strong -fstack-clash-protection -fcf-protection=full\".     <\/p>\n<p>It is noted that work is currently underway to add security enhancement capabilities to the C and C++ standards, but this process is not quick. Meanwhile, specific options with additional protection mechanisms are already available in Clang. The implemented protection methods often lead to individual incompatibilities with existing code or ABI violations, making it impossible to activate them by default. Additionally, such options are fragmented (flags for controlling compilation, machine instruction generation flags tied to hardware architectures, warnings, diagnostic modes, macros), poorly documented, and tend to fall off the radar of many developers.       <\/p>\n<p>The unified configuration standardizes the inclusion of security-related options and simplifies their application. Several activation methods for the enhanced security mode are being considered, such as activation via the flag \"-fhardened\", a configuration set \"--config=hardened\", a separate driver (clang --driver-mode), or individual options \"-fhardened, -mhardened, and -Whardened\" linked to compilation, code generation, and warning outputs. The mode may encompass:  <\/p>\n<ul>\n<li class=\"l\"> Compiler capabilities: -ftrivial-auto-var-init, -fPIE, -fcf-protection, etc.\n<li class=\"l\"> Features related to code generation for target platforms: -mspeculative-load-hardening, -mlvi-hardening, etc.\n<li class=\"l\"> Warnings: -Wall, -Wextra, -Werror=return-type, etc.\n<li class=\"l\"> Security enhancement modes in the standard function library.\n<li class=\"l\"> Macros: _FORTIFY_SOURCE, _GLIBCXX_ASSERTIONS, etc.\n<li class=\"l\"> Requirement for an explicit choice of the language standard used.\n<li class=\"l\"> Refusal to compile code using deprecated C89 and C++98 standards.\n<li class=\"l\"> Passing additional flags to the linker, for example, to enable address randomization.  <\/ul>\n<p>Source: <a
