From: Cédric Le Goater Date: Wed, 12 Jan 2022 10:28:26 +0000 (+0100) Subject: target/ppc: Add extra float instructions to POWER5P processors X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=91137619c6555a3c7cdd829f3b91b6da2bf67475;p=qemu.git target/ppc: Add extra float instructions to POWER5P processors ISA v2.03 introduced Floating Round to Integer instructions : frin, friz, frip, and frim. Add them to POWER5+. The PPC_FLOAT_EXT flag also includes the fre (Floating Reciprocal Estimate) instruction which was introduced in ISA v2.0x. The architecture document says its optional and that might be the reason why it has been kept under the PPC_FLOAT_EXT flag. This means 970 CPUs can not use it under QEMU, which doesn't seem to be a problem.
