[LLVMdev] Porting to System z
...llvm::TreePatternNode::hasTypeSet() const':
CodeGenDAGPatterns.h:187: warning: comparison between signed and unsigned
integer expressions
Using gdb to see what may be happening shows that the value is llvm::MVT::i8
that it is having problems with. I assume it must be failing the
MVT(VT).isInteger() test, so I added some logic to break down the test:
144 bool isInt = MVT(VT).isInteger();
(gdb) n
145 bool isSim = MVT(VT).isSimple();
(gdb) p isInt
$1 = false
(gdb) n
146 if (MVT(VT).isInteger()) {
(gdb) p isSim
$2 = true
So you'd assume it's the tests in isInteger()...

[LLVMdev] Assert in SelectionDAGLegalize when using arbitrary size integers
...eplacing the
Int32Ty with another size (let's say 12 bits for the example). While
it compiles ok, I get the following assert at run-time:

[LLVMdev] Porting to System z
Hi,
I am beginning the porting process for Linux on System z (aka IBM
Mainframe). I thought I¹d build LLVM first with the c and cpp backends so
that tools like TableGen would be created that I¹d then use to process the
.td files that I¹ll be creating. So I used svn to grab the code from the
repository and ran configure and make. However, the build breaks at this
point:

Will/Can Exchange Server run with a samba pdc?
Its not for us.
We migrated from our nt4 pdc to samba pdc last night with good outcomes
as far as our clients but our exchange server no longer works.
It failed initially as we did not have the" log on as a service user"
(not strictly true, we had administrator but it didn't work for some reason)
After we got a working service user then got "service specific error
