Subject: [dpdk-dev] RTM instruction compile failure for XABORT when AVX is active
Date: Sun, 28 Jun 2015 10:16:24 -0700	[thread overview]
Message-ID: <1A87AD2E-38CD-4C61-A9FD-C52608FF9DAC@mhcomputing.net> (raw)

Hi all,

I am getting a strange error compiling some RTM instructions when I upgraded my VM environment from VirtualBox 4 to VirtualBox 5 and AVX instructions from the host CPU became available. However when I am reading the opcode description for XABORT it supposedly allows an immediate operand for the argument so I can't understand why this code would not compile. Any advice?

        asm volatile(".byte 0xc6,0xf8,%P0" :: "i" (status) : "memory");
