Adding pragma llvm_inline_ir.
Improved the error messages.
Append "ret void" when the return type is void
Improved the error message
in case when the string passed as llvm inline ir isn't valid llvm
assembly language.
LLVM 3.2 fix.
Add attribute AlwaysInline inside DtoInlineIRFunction.
Always generate a body for llvm_inline_ir
Also, always make llvm_inline_ir functions linkonce_odr. Because
the body is always generated when a module uses a llvm_inline_ir
function, the fact that the linker removes the function shouldn't
cause problems.
Previously, set_param_attrs would overwrite any pre-existing
attributes, which is problematic, as per-function attributes are
also stored in a slot in that attribute list. This for example
lead to "noinline" being dropped for functions with inline asm.
NChybrid was the only one that didn't instantly trigger a "not
implemented" assertion on any code using nested function for a long
time, and removing the cruft greatly improves code readability
(maintainability is a moot point anyway given its current state).
Previously, we just had a hack to make ref foreach statements work.
This commit enables them to work in other cases as well, like the
implicit __result variable for functions with out-contracts (which
is such a magic ref variable for ref-returning functions).
Fixes DMD testcase 'testcontracts'.
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.
Previously, LDC would crash in the backend due to the fact that the IR is typed in such cases (we recently had such an instance with Tango, where an extern( C ) function was declared once with int and once with size_t).
This will disable the usage of the 'red-zone' in ABIs that make use of it (like x86). This mimics the exact flag used by clang. It is comparable to the -mno-red-zone flag in gcc. - thanks to wilkie
