From d7274dbf82001ae52e5c9a514129b49152498d40 Mon Sep 17 00:00:00 2001 From: Michael Meissner Date: Tue, 9 Jun 2020 15:35:43 -0500 Subject: [PATCH] PowerPC: Add future hwcap2 bits This patch adds support for the two new HWCAP2 fields used by the __builtin_cpu_supports function. It adds support in the target_clones attribute for -mcpu=future. The two new __builtin_cpu_supports tests are: __builtin_cpu_supports ("isa_3_1") __builtin_cpu_supports ("mma") The bits used are the bits that the Linux kernel engineers will be using for these new features. gcc/ 2020-06-09 Michael Meissner * config/rs6000/ppc-auxv.h (PPC_PLATFORM_FUTURE): Allocate 'future' PowerPC platform.
