Subject: [PATCH] Fix inline functions to use 'static inline'
|
|
|
|
With just 'inline', if the compiler decides not to inline them, it isn't
|
|
required to emit them at all. For some targets with -Os that is causing
|
|
build failures, see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86360.
|
|
|
|
Perhaps we might consider using '__attribute__((always_inline))' for
|
|
GCC builds, but 'static inline' is a good start.
