Nettetcode for later link-time optimization is stripped. When multiple object files are linked together the resulting code is better optimized than with link-time optimizations disabled (for example, cross-module inlining happens), but most of benefits of whole program optimizations are lost. Nettet1. mai 2024 · Whole program optimization includes (practically, at least for C or C++ and similar languages) inlining across translation units, so is sometimes (improperly) called link-time optimization (LTO), but still is done by the compiler also running during the linking step. BTW, LTO existed at least since the 1990s (and probably even in the …

Nettet20. aug. 2024 · Unfortunately, linkers do not perform optimizations by default. To enable dead code optimization on GCC, you need two things: the compiler needs to split each function into its own linker section so the linker knows where each function is, and the linker needs to add an optimization pass to remove sections that are not called by … Nettet2. jun. 2024 · June 2012: Port to clang. In addition to quicker compilation, this also enabled better tooling (e.g. sanitizers that weren’t on par in gcc at that time). Developers can use either gcc or clang.
