I hope I have untangled the checks for "native" Windows (Triple::Win32)
vs. Windows/MinGW/Cygwin (Triple::isOSWindows) correctly.
MinGW needs some default libraries as well, has to be fixed later.
DMD has the obscure functionality to install functions starting with
_STI_ as global ctors and funtions starting with _STD_ as global
dtors. IMHO a pragma is a better way to specify the behaviour.
This commit adds pragma(LDC_global_crt_ctor) and
pragma(LDC_global_crt_dtor). If the pragma is specified on a function
or static method then an entry is made in the corresponding list. E.g.
in monitor_.d:
extern (C) {
#pragma(LDC_global_crt_ctor)
void _STI_monitor_staticctor()
{
// ...
}
}
This works on Linux without problems. On Windows with MS C Runtime
ctors work always but dtors are invoked only if linked against the
static C runtime. Dtors on Windows require at least LLVM 3.2.
I removed the copyright notice. I don't think we are obliged to
display it for DMD; on the other hand, if we do, we might also
have to display the libconfig one (LGPL). Thus, this seemed like
the better choice.
The indentation is to align with the registered target output,
which we cannot control.
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.
A lot of system specific knowledge is already present in LLVM. This is used to populate several fields in global.params instead of hard coded values in main(). Ensures that the frontend and LLVM have always the same values.
The string representation of the data layout is retrieved from the TargetData class (in main) and passed via global.params.dataLayout to the module. Since the gTargetData is also a global variable it makes no sense to pass this information using another global variable.
- New functions codeGenOptLevel() and verifyModule() to remove code duplication
- Hidden option no-verify renamed to disable-verify and moved to optimizer (like opt tool)
- Removed global.params.noVerify
- Wraps some LDC specific code in 'IN_LLVM' section
- Adds some MSVC specific code to 'IN_LLVM' section
- Removes an unused include file
Net result is much less errors with MSVC.
