Re: [ydl-gen] String instructions emulation on PPC970MP

2009-12-09 Thread Patrice Bouchand
Hello, Actually, when I run the code with dlmzb on the 970 cpu, I get a SIGILL and what I would love to do is actually to add a hook on it to be able to run the code compiled with mcpu=440fp directly on the power-station. I do not think it's already done and as you said, it seems quite

[ydl-gen] String instructions emulation on PPC970MP

2009-12-08 Thread Patrice B
Hello, I'm using a Power Station as a build machine to generate code for amcc440 cpu using gcc 4.4 with option -mcpu=440fp. Since this release of gcc, I notice that code is generated with string instructions which are not supported by Power Station cpu, and then, it makes build failed if a

Hi Patrice: I did a little digging and came across the following explanation from IBM which explains that the CPU you are coding for (amcc440) requires a specific Linux capable of the following: In versions 2.6.26 and earlier of the Linux kernel, the code did not properly clear reserved bits 11
