} Subject: Add support for new Pentium Pro instructions to GAS } Date: 10 Jan 1996 19:26:20 -0500 } Organization: GNUs Not Usenet } Lines: 232 } Sender: daemon@cis.ohio-state.edu } Approved: bug-gnu-utils@prep.ai.mit.edu } Distribution: gnu } Message-ID: <199601102305.PAA09618@ichips.intel.com> } } } Below is a patch relative to Binutils 2.6 that adds new Pentium Pro } instructions to the i386 instruction set. Both the assembler and } disassembler were updated. This is very welcome news indeed. } } If I get time, I plan on updating GCC to do minimal P6 optimizations. } (It really doesn't need much, but some things do help.) Well, it needs something, so that it is not 40% slower than the Intel reference compiler on the fastest P5s and P6s. Maybe it isn't very complicated to put in the logic to do the proper scheduling of fadd/fmul and fxch. Still, great news. } } Enjoy, } Wayne } } Wayne Scott P6 Architecture } wscott@ichips.intel.com Work #: (503) 264-4165 } Disclaimer: All views expressed are my own opinions, and not necessarily } those of Intel Corporation. } Russell
