How to build highly-debuggable C++ binaries

Assuming spatulas are absent, I've never had a problem with the build system on Linux. Nonetheless, for GCC the equivalent is:

  #pragma GCC optimize ("O0")

(see also target, push_options, and pop_options)

This is also available as a per-function attribute, using both gnu and standard syntaxes:

  __attribute__((optimize("O0")))
  [[gnu::optimize("O0")]]

For completeness, in Clang `[[clang::optnone]]` as a per-function attribute also works fine. I'm using it for debugging quite frequently lately.
