- Subject: config.guess change for solaris
The intent here is to be able to distinguish a machine
that can execute 64-bit binaries from one that cannot.
This is hindered by the fact that one can install a
32-bit only kernel on a machine otherwise capable of
64-bit operation.
We're using the following designations in gcc 3.1:
sparc-solaris 32-bit only
sparcv9-solaris 32-bit default, 64-bit capable
sparc64-solaris 64-bit default
Note that config.guess never chooses sparc64-solaris.
With the sparcv9 configury, one can use -m64 if you
want to generate 64-bit code.
r~
* config.guess (sun4u:SunOS:5.*:*): Guess sparcv9 if 64-bit isa
is supported.
