* powerpc: Enforce compiler barriers on hardware transactionsTulio Magno Quites Machado Filho2016-01-081-1/+1
| | | | | | | Work around a GCC behavior with hardware transactional memory built-ins. GCC doesn't treat the PowerPC transactional built-ins as compiler barriers, moving instructions past the transaction boundaries and altering their atomicity.

* powerpc: abort transaction in syscallsAdhemerval Zanella2015-01-121-0/+22
| | | | | | | | | | | Linux kernel powerpc documentation states issuing a syscall inside a transaction is not recommended and may lead to undefined behavior. It also states syscalls does not abort transactoin neither they run in transactional state. To avoid side-effects being visible outside transactions, GLIBC with lock elision enabled will issue a transaction abort instruction just before all syscalls if hardware supports hardware transactions.

* Allow sys/auxv.h to be used from the testsuite on powerpc and sparc.Adam Conrad2014-02-211-1/+1
| | | | | | | | | | | | | | | | elf/tst-auxv.c includes misc/sys/auxv.h, which ends up not actually being included due to the guard overlap, and getauxval becomes an implicit declaration and implicit pointer conversion which means, at best, the test isn't actually testing what it thinks it is and, at worst, it'll crash and burn on platforms where implict pointer conversion is a Very Bad Thing. * sysdeps/powerpc/bits/hwcap.h: Allow _SYSDEPS_SYSDEP_H guard as a synonym for _SYS_AUXV_H to allow direct inclusion. * sysdeps/sparc/bits/hwcap.h: Likewise. * sysdeps/powerpc/sysdep.h: Define _SYSDEPS_SYSDEP_H instead of _SYS_AUXV_H so we can include sysdep.h and sys/auxv.h together. * sysdeps/sparc/sysdep.h: Likewise.
