this came up before IIRC, but I don't remember the details - buggy system
compiler? Try searching the archives. Also, if you

[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:

...er 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() that are failing:
/// isInteger - Return true if this is an integer, or a vector integer
type.
bool isInteger() const {...
