libstdc++: Mark non-exported function always_inline [PR105671]
|
|
|
|
This new function was added for gcc 11.1 but is not exported from the
|
|
shared library. Depending on inlining decisions, its callers might get
|
|
inlined but an external definition be needed for this function. That
|
|
then fails to link.
|
|
|
|
Since we can't add the export to the gcc-11 release branch now, mark it
|
|
always_inline. We can consider exporting it for gcc-13 if/when we bump
|
|
the shared library version (and maybe also for gcc-12 which is currently
|
|
at the same version as trunk). For now, the attribute will solve the
|
|
problem on all affected branches. The function is small enough that
|
|
force-inlining it shouldn't cause problems.
