A post by Daniel Lemire questions whether C++ constructors should be defined as = default, citing notable performance effects in recent GCC versions.
A post by Daniel Lemire questions whether C++ constructors should be defined with = default, stating that this may have notable negative performance effects in recent GCC versions. According to the source, choosing = default or explicit constructor bodies may affect compile time or the generated code. The author points to his articles for more details, which should be consulted at the original page.
For developers working with the GCC compiler, the point is practical: measure compile time and performance on the version you use before adopting a pattern.
