------------
- You need GCC 3.4 or later to compile the s390 port.
- A working combination of autotools is required.
-- To run valgrind a z900 machine or any later model is needed.
+- To run valgrind a z10 machine or any later model is needed.
+ Older machine models down to and including z900 may work but have
+ not been tested extensively.
Limitations
-----------
- 31-bit client programs are not supported.
- Hexadecimal floating point is not supported.
-- memcheck, massif, lackey, and none are supported.
-- cachegrind is supported on z10 and newer models. On older models,
- a z10 cache architecture will be assumed.
+- memcheck, cachegrind, drd, halgrind, massif, lackey, and none are
+ supported.
+- On machine models predating z10, cachegrind will assume a z10 cache
+ architecture. Otherwise, cachegrind will query the hosts cache system
+ and use those parameters.
- callgrind and all experimental tools are currently not supported.
-- helgrind and drd seem to work on SLES10,11 and RHEL5,6 on z9,z10 and z196
- but might fail on other hardware/software combinations.
- Some gcc versions use mvc to copy 4/8 byte values. This will affect some
debug messages. Valgrind will complain about 4 or 8 one-byte reads/writes
instead of just 1 read/write.
