|
+Requirements
|
|
+------------
|
|
+- You need GCC 3.1 or later to compile the s390 port.
|
|
+- A working combination of autotools is required. The following
|
|
+ combination is known to work: automake 1.9.6 and autoconf 2.59
|
|
+- To run valgrind a z900 machine or any later model is needed.
|
|
+- The long displacement facility must be installed on the host machine.
|
|
+
|
|
+
|
|
+Limitations
|
|
+-----------
|
|
+- 31-bit client programs are not supported.
|
|
+- Hexadecimal floating point is not supported.
|
|
+- Decimal floating point is not supported yet.
|
|
+- Currently, only memcheck, massif, lackey, and none are supported
|
|
+- helgrind and drd seem to work but are not yet supported.
|
|
+- exp-ptrcheck and callgrind are not supported.
|
|
+
|
|
+
|
|
+Recommendations
|
|
+---------------
|
|
+Applications should be compiled with -fno-builtin to avoid
|
|
+false positives due to builtin string operations when running memcheck.
|
|
+

|
|
+ - A mapping from IRTemp to IRType, giving the type of any IRTemp we
|
|
+ might encounter. This is computed before insn selection starts,
|
|
+ and does not change.
|
|
+
|
|
+ - A mapping from IRTemp to HReg. This tells the insn selector
|
|
+ which virtual register(s) are associated with each IRTemp
|
|
+ temporary. This is computed before insn selection starts, and
|
|
+ does not change. We expect this mapping to map precisely the
|
|
+ same set of IRTemps as the type mapping does.
|
|
+
|
|
+ - vregmap holds the primary register for the IRTemp.
|
|
+ - vregmapHI holds the secondary register for the IRTemp,
|
|
+ if any is needed. That's only for Ity_I64 temps
|
|
+ in 32 bit mode or Ity_I128 temps in 64-bit mode.
|
|
+
|
|
+ - The name of the vreg in which we stash a copy of the link reg,
|
|
+ so helper functions don't kill it.
|
|
+
|
|
+ - The code array, that is, the insns selected so far.
|
|
+
|
|
+ - A counter, for generating new virtual registers.
|
|
+
|
|
+ - The host subarchitecture we are selecting insns for.
|
|
+ This is set at the start and does not change.
|
|

|
|
+ Perform a syscall for the client. This will run a syscall
|
|
+ with the client's specific per-thread signal mask.
|
|
+
|
|
+ The structure of this function is such that, if the syscall is
|
|
+ interrupted by a signal, we can determine exactly what
|
|
+ execution state we were in with respect to the execution of
|
|
+ the syscall by examining the value of NIP in the signal
|
|
+ handler. This means that we can always do the appropriate
|
|
+ thing to precisely emulate the kernel's signal/syscall
|
|
+ interactions.
|
|
+
|
|
+ The syscall number is taken from the argument, since the syscall
|
|
+ number can be encoded in the svc instruction itself.
|
|
+ The syscall result is written back to guest register r2.
|
|
+
|
|
+ Returns 0 if the syscall was successfully called (even if the
|
|
+ syscall itself failed), or a nonzero error code in the lowest
|
|
+ 8 bits if one of the sigprocmasks failed (there's no way to
|
|
+ determine which one failed). And there's no obvious way to
|
|
+ recover from that either, but nevertheless we want to know.
