From 93a739d4a1c34c9dbb96ced4fbeaa18e02000b6a Mon Sep 17 00:00:00 2001 From: Manjunath Matti Date: Tue, 5 Dec 2023 06:38:47 -0600 Subject: powerpc: Add space for HWCAP3/HWCAP4 in the TCB for future Power. This patch reserves space for HWCAP3/HWCAP4 in the TCB of powerpc. These hardware capabilities bits will be used by future Power architectures. Versioned symbol '__parse_hwcap_3_4_and_convert_at_platform' advertises the availability of the new HWCAP3/HWCAP4 data in the TCB. This is an ABI change for GLIBC 2.39.
