Grand Day,
To those grand people running SLE11 on zLinux. I'm showing gcc
at 4.3.2, which means no support for the new z10 instructions and the
decimal goodies. I'm being told, SLE 11.0 was shipped with gcc 4.3.3
which does have all the goodies...
Is it just me missing an update / APAR or a typo I have made ???
Comments very welcome....

S/390, zSeries and System z9
* Support for the IBM System z9 EC/BC processor (z9 GA3) has been
added. When using the -march=z9-ec option, the compiler will generate
code making use of instructions provided by the decimal floating point
facility and the floating point conversion facility (pfpo). Besides the
instructions used to implement decimal floating point operations these
facilities also contain instructions to move between general purpose and
floating point registers and to modify and copy the sign-bit of floating
point values.
* When the -march=z9-ec option is used the new
-mhard-dfp/-mno-hard-dfp options can be used to specify whether the
decimal floating point hardware instructions will be used or not. If
none of them is given the hardware support is enabled by default.
* The -mstack-guard option can now be omitted when using stack
checking via -mstack-size in order to let GCC choose a sensible stack
guard value according to the frame size of each function.
* Various changes to improve performance of generated code have been
implemented, including:
o The condition code set by an add logical with carry
instruction is now available for overflow checks like: a + b + carry <
b.
o The test data class instruction is now used to implement
sign-bit and infinity checks of binary and decimal floating point
numbers.
