help
Userspace implementation of the Read-Copy-Update (RCU)
synchronization mechanism. This library is mainly used by
the LTTng tracing infrastructure, but can be used for other
purposes as well.
liburcu: disable build with gcc-4.8.x on ARM Because of a gcc bug [1], liburcu checks for compiler version [2] and stops the build prematurely if gcc-4.8.[0-2] is detected for ARM. However a bug fix exists [3] and may be backported by ARM toolchain providers; that's what is done in Buildroot [4] or Linaro [5]. So, this change: - add a patch in liburcu to allow build with ARM gcc-4.8.2; - adds a new hidden symbol to reflect the toolchain status with regard to this bug [1]; - and controls liburcu visibility. However, a limitation of this is when the user is using a custom toolchain; that's why the bug details have been added in the liburcu help message.
