Fix building glibc master with NDEBUG and --with-cpu.
|
|
|
c6d234 |
|
|
|
c6d234 |
When building on i686, x86_64, and arm, and with NDEBUG, or --with-cpu
|
|
|
c6d234 |
there are various variables and functions which are unused based on
|
|
|
c6d234 |
these settings.
|
|
|
c6d234 |
|
|
|
c6d234 |
This patch marks all such variables with __attribute__((unused)) to
|
|
|
c6d234 |
avoid the compiler warnings when building with the aformentioned
|
|
|
c6d234 |
options.
