* Introduce a DRValue base class to be able to discriminate between
DLValues and DRValues (e.g., function parameters).
* Let DValue::getRVal() return each DValue's value as DRValue.
This allows to convert a DLValue to a DRValue, a snapshot of the
lvalue's current state, while retaining the D type, something we've
previously lost when returning the low-level rvalue directly.
* Let the DtoR/LVal() helpers be the only way to convert a DValue to a
low-level value.
All DValues are now required to have a (main) LL value, which allows
to conveniently refactor the DValue hierarchy.
DSliceValue now represents a LL struct instead of separate values for
length and pointer.
Use the existing public field directly instead.
It's shorter and different than LLValue's getType() (making it easier
to discriminate DValues and LLValues for experienced LDC devs imho).
DSliceValue is still a special case and contains pointer and length
separately, which are packed to a LL struct in getRVal().
It'd probably pay off to do it the other way around and store the LL
struct as single value and allowing for access to the components.
This should put an end to the "instruction does not dominate all uses"
ICEs triggered by the new cleanup code, such as GitHub #1294 and other
reports before that.
The root cause was that the code assumed that DVarValues were always
either globals or pointed to allocas in the function entry basic block,
whereas DVarValue is really just a generic lvalue.
The relationship between them is at best tenuous; DVarValue should
probably be renamed to DLValue and is used right now to describe
a general lvalue, of which variables are just one example.
This is in preparation of removing it entirely. In the contexts
where it was used, the information about the variable declaration
was directly available anyway. Instead, we now use the AST directly
like the DMD glue code does.
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.
Changed runtime functions taking opaque[] to void[].
Implemented proper type painting, to avoid "resizing" array casts in runtime calls that previously took opaque[].
Implemented dynamic arrays as first class types, this implements proper ABI for these types on x86.
Added dwarf region end after call to assert function, fixes some problems with llvm not allowing this to be missing.
Reverted change to WithStatement from rev [704] it breaks MiniD, mini/with2.d needs to be fixed some other way...
Fixed tango bug 1339 in runtime, problem with _adReverseChar on invalid UTF-8.
Disabled .bc generation in the compiler runtime part, genobj.d triggers some llvm bug when using debug info. the .o seems to work fine.
Reimplemented support for nested functions/class using a new approach.
Added error on taking address of intrinsic.
Fixed problems with the ->syntaxCopy of TypeFunction delegate exp.
Removed DtoDType and replaced all uses with ->toBasetype() instead.
Removed unused inplace stuff.
Fixed a bunch of issues in the runtime unittests, not complete yet.
Added mini tests.
Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array.
Applied patch to tango/text/convert/Layout.d by fvbommel, closes#47 .
Cleaned up some type code.
Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant.
Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/
