Debug information is based on static lexical blocks. Most calls to
EmitFuncEnd() are done if control flow reaches the end of the
function which is quite different.
This leads to serious problems for values we really should
not be loading from, such as 100k element static arrays.
It was hard to figure out exactly why we need to emit DWARF
info here, so the easiest solution is to just have a look
at assignments during the next big debug info push.
With a single byte (implicit and 0) as initializer, as each void
element occupies 1 byte.
This is required when building T.init for a struct T containing
a void[N] with N > 0 and building literals of T.
This is required for the GC to be able to call their dtors, if need
be (by appending a TypeInfo pointer after the actual struct in case
the struct has a dtor).
_d_newitemT() / _d_newitemiT() also perform the initialization, so
we don't need to take care of that in toir.cpp anymore.
Runtime function _d_delarray_t() expects the TypeInfo_Struct argument
to be null if the struct has no dtor.
This fixes runnable/hospital.d, which deletes a dynamic array of class
handles. But in this case, we only delete the memory allocated for the
handles and don't destruct the actual class instances!
For hospital.d, it doesn't matter as the class has no dtor.
But I doubt that's intended behavior...
Includes all tagged with v2.067.0-b2. Does not includes latest druntime changes from ldc (head) branch.
This is known to be broken. I only merged the frontend stuff but did not try to compile something...
First merge of current development stream. Asm blocks are known to be broken.

This fixes a regression introduced in caa2f15c8a. The IrDsymbol
metadata is obviously reset in between modules, while IrTypes
are not. Thus, we can never set symbol metadata when resolving
types, as the symbol data will be wrong in all modules following
the one where the type was first resolved.
GitHub: Fixes#739.
It seems like the original code contained two issues: First,
the stopOnStatic branch checked the passed symbol over and
over again instead of the current parent. Second, aggregate
declarations are not Declarations, they are ScopeDsymbols.
GitHub: Fixes#696.
It is no longer needed now that we use DMD's model for determining
whether to emit templates. We might also be able to use the more
general tinst/minst machinery from DMD Git master if we ever need
something similar.
