1. Main include corresponding to .cpp file, if any.
2. DMD and LDC includes.
3. LLVM includes.
4. System includes.
Also updated a few include guards to match the default format.
The previous solution was problematic because the change was language-
visble via the isUnsigned trait. Now, pointers are simply explicitly
checked for in the relevant places. (Note that there might be cases in
the diff where a direct isunsigned() call would have been appropriate –
I only checked for instances where the type clearly cannot be a pointer,
but chose to go the safe route in replicating existing behavior
otherwise).
Fixes DMD testcase 'traits'.
This is based on Item 2 of "More Effective C++". In general, the C++ cast operators are more expressive and easy to find,
e.g. by grep. Using const_cast also shuts up some compiler warnings.
On OS X, there is an actual significance to the distinction, which before lead e.g. to exception throwing in the below example being broken:
---
import core.exception;
void main() {
asm {
jmp Lfoo;
Lfoo:
;
}
throw cast(OutOfMemoryError)cast(void*)OutOfMemoryError.classinfo.init;
assert(0);
}
---
1) The last parameter of getGetElementPtr() has type bool. In some instances, a 2 is used as parameter. This is converted to true.
2) Several loops use int instead of unsigned. This causes warning about signed/unsigned mismatch.
Curiously, only Visual C++ complains about this. Nevertheless I think that the warnings should be fixed.
Before, _d_arraycatT was used to concatenate multiple arrays. That caused an issue when postblit
was called on a struct multiple times. The next code asserted due to the issue:
void main()
{
static struct S
{
int x;
int pad;
this(this)
{
++x;
}
}
auto sarr = new S[1];
auto sarr2 = sarr ~ sarr ~ sarr;
assert(sarr2[0].x == 1);
assert(sarr2[1].x == 1);
assert(sarr2[2].x == 1);
assert(sarr[0].x == 0);
}
Removed use of dyn_cast, llvm no compiles
without exceptions and rtti by
default. We do need exceptions for the libconfig stuff, but rtti isn't
necessary (anymore).
Debug info needs to be rewritten, as in LLVM 2.7 the format has
completely changed. To have something to look at while rewriting, the
old code has been wrapped inside #ifndef DISABLE_DEBUG_INFO , this means
that you have to define this to compile at the moment.
Updated tango 0.99.9 patch to include updated EH runtime code, which is
needed for LLVM 2.7 as well.
