* Remove default label in switch which covers all enumeration values.
This fixes the warning "default label in switch which covers all enumeration values". We will already get a warning when _not_ all enumeration values are covered.
This is the last warning left on OSX/Clang, so with this change, we can build with -Werror.
* Fix warning: enumeral and non-enumeral type in conditional expression
* Fix warning: '%d' directive output may be truncated writing between 1 and 10 bytes into a region of size 5
* "fallthrough" is recognized by the compiler warning system
Invoke nothrow callees only in try-blocks with at least 1 catch-block,
otherwise call them directly.
Errors thrown by nothrow callees can thus still be caught inside a
try-catch-statement (and this is apparently required for release builds
too).
Most calls will be direct calls though, and this small change will lead
to substantially less IR as we then skip the clean-ups after an Error.
Proper clean-up when unwinding after an Error seems not to be guaranteed
anyway. There are apparent RAII front-end optimizations for structs with
nothrow dtor - see PR #1656.
Previously, the transitory state only needed and valid during
generation of the LLVM IR for the function body was conflated
with the general codegen metadata for the function declaration
in IrFunction.
There is further potential for cleanup regarding the use of
gIR->func() and so on all over the code base, but this is out
of scope of this commit, which is only concerned with those
IrFunction members moved to FuncGenState.
GitHub: Fixes#1661.
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).
Allow ABIRewrites to return the D parameter's LL value directly.
Most rewrites store to memory anyway, so let the D parameter point
directly to that memory instead of a dedicated alloca bitcopy.
Also adds the CMake infrastructure to compile and link the D source files.
The build is partially broken:
- A few files in Phobos and druntime do not build
- MSVC build is broken because of unresolved symbols involving reals
And for sret args too, except for MSVC targets.
At least on Win64, the sret align attributes lead to ICEs for std.bitmanip
and std.uni (release only), when computing the known alignment in the LLVM
inliner pass:

Q.CxtI->getParent()->getParent() && "Got assumption for the wrong function!",
