Tcl: 8.5.12
OS: Solaris 5.10 on AMD64

Doing a

$ sh .../tcl8.5/unix/configure --enable-64bit --prefix=`pwd`/..
$ make test

gives one failing test case:

==== platform-3.1 CPU ID on Windows/UNIX FAILED
==== Contents of test case:

set cpudata [testcpuid 0]
binary format iii [lindex $cpudata 1] [lindex $cpudata 3] [lindex $cpudata 2]

---- Result was:
�� )D
---- Result should have been (regexp matching):
^(?:AuthenticAMD|CentaurHauls|CyrixInstead|GenuineIntel)$
==== platform-3.1 FAILED

    Interesting. Exactly what processor does this machine have?

    Forgot to mention that the expected result should have been "AuthenticAMD" (according to kstat)!

    kstat -m cpu_info

    Is the attached kstat-output enough, or do you want something else?

    According to what I can find, I would expect "AuthenticAMD" as well.
    See:

    That page is about the cpuid device, not about the cpuid assembler instruction.
    Part of this page:
    >The device is useful to enable low-level configuration information to

    > to invoke the cpuid instruction directly.
    Well, Tcl now contains the assembler code which invokes the cpuid
    instruction directly, so it should simply work..

    It will need some debugging. The assembler code is
    borrowed from: <http://en.wikipedia.org/wiki/CPUID>
    and can be found in unix/tclUnixCompat.c:990-995.

    After some further searching in the net and talking with a fellow developer, I used a different compiler. And see ... it works there. So Studio 12 isn't a good choice to use here, Studio 12.1 works, however. So it can be closed.

    Sorry for any inconvenience.
