Remove miscellaneous GCC >= 4.7 version conditionals.
This patch removes miscellaneous __GNUC_PREREQ (4, 7) conditionals
that are now dead.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
* sysdeps/arm/atomic-machine.h
[__GNUC_PREREQ (4, 7) && __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4]:
Change conditional to [__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4].
[__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 && !__GNUC_PREREQ (4, 7)]:
Remove conditional code.
[!__GNUC_PREREQ (4, 7) || !__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4]:
Change conditional to [!__GCC_HAVE_SYNC_COMPARE_AND_SWAP_4].
* sysdeps/i386/sysdep.h [__ASSEMBLER__ && __GNUC_PREREQ (4, 7)]:
Change conditional to [__ASSEMBLER__].
[__ASSEMBLER__ && !__GNUC_PREREQ (4, 7)]: Remove conditional code.
[!__ASSEMBLER__ && __GNUC_PREREQ (4, 7)]: Change conditional to
[!__ASSEMBLER__].
[!__ASSEMBLER__ && !__GNUC_PREREQ (4, 7)]: Remove conditional
code.
* sysdeps/unix/sysv/linux/sh/atomic-machine.h (rNOSP): Remove
conditional macro definitions.
(__arch_compare_and_exchange_val_8_acq): Use "u" instead of rNOSP.
(__arch_compare_and_exchange_val_16_acq): Likewise.
(__arch_compare_and_exchange_val_32_acq): Likewise.
(atomic_exchange_and_add): Likewise.
(atomic_add): Likewise.
(atomic_add_negative): Likewise.
(atomic_add_zero): Likewise.
(atomic_bit_set): Likewise.
(atomic_bit_test_set): Likewise.
* sysdeps/x86_64/atomic-machine.h [__GNUC_PREREQ (4, 7)]: Make
code unconditional.
[!__GNUC_PREREQ (4, 7)]: Remove conditional code.
