There were two aspects of this behavior that were considered undesirable: - Although the safe inlining is in general desirable it should only be enabled if asked for it - like any other optimization. - The option name -Os implies that it is a safe option, the potentially unsafe inlining should have a more explicit name. So now: - The option -Os enables the safe inlining. - The new option --eagerly-inline-funcs enables the potentially unsafe inlining (including the safe inlining). Additionally was added: - The option --inline-stdfuncs that does like -Os enable the safe inlining but doesn't enable optimizations. - The pragma inline-stdfuncs that works identical to --inline-stdfuncs. - The pragma allow-eager-inline that enables the potentially unsafe inlining but doesn't include the safe inlining. That means that by itself it only marks code as safe for potentially unsafe inlining but doesn't actually enable any inlining.
