Subject: Add AArch64 HWCAPs from Linux 5.0.
X-Git-Tag: upstream/2.30~276
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a2e57f89a35e6056c9488428e68c4889e114ef71;p=platform%2Fupstream%2Fglibc.git

Add AArch64 HWCAPs from Linux 5.0.

This patch adds new AArch64 HWCAPs from Linux 5.0 to the AArch64
bits/hwcap.h and dl-procinfo.c.

Tested (compilation only) with build-many-glibcs.py for
aarch64-linux-gnu.

	* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SB): New
	macro.
	(HWCAP_PACA): Likewise.
	(HWCAP_PACG): Likewise.
	* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
	Increase to 32.
	(_dl_aarch64_cap_flags): Add new entries for new HWCAPs.
