Studio 12 EA support for AMD Barcelona Processors

I use -xtarget=native when i compile programs for my pc, because it expands in to -xarch, -xchip and -xcache suitable for my system. For optimized compiling i use -fast. This option already contains -xtarget=native. For 64-bit programs -xtarget=native64. If you want to see expanded values just use -dryrun. I dont know if this is best way but it works fine.

Edit:

My cpu:

Status of virtual processor 0 as of: 04/23/2007 11:20:59

on-line since 04/23/2007 10:16:17.

The sparcv9 processor operates at 1503 MHz,

expanded values:

-xtarget=native:

-xarch=v8plusb -xcache=64/32/4:1024/64/4 -xchip=ultra3i

-xtarget=native64:

-xarch=v9b -xcache=64/32/4:1024/64/4 -xchip=ultra3i

For Sun Studio 12, please, use -m64 to get 64bit code.

For this particular case you should use -xtarget=native -m64 combo.

You can ask them to run "fpversion" binary from your EA bits.

For Sparc VI I believe the right target will be -xtarget=sparc64vi though I'm not sure it will work in EA perfectly right.

Chris,

Unfortunately the READMEs / Release Notes in SS12 EA mainly point me to the SS11 documentation, which isn't entirely surprising since it is not GA software yet. I can't find anything else of use in the documentation provided.

If someone from Sun would just answer if the Barcelona processor has a specific -xchip option and if so what they are, then that is all I need.

I will try -xtarget=sparc64vi as you suggest Fedor

Thanks, Rob.
