Move __PTHREAD_SPINS definition to architecture specific header
|
|
|
00db10 |
|
|
|
00db10 |
This patch moves the __PTHREAD_SPINS definition to arch specific header
|
|
|
00db10 |
since pthread_mutex_t layout is also arch specific. This leads to no
|
|
|
00db10 |
need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the
|
|
|
00db10 |
undefined compiler warning.
