The previous solution was problematic because the change was language-
visble via the isUnsigned trait. Now, pointers are simply explicitly
checked for in the relevant places. (Note that there might be cases in
the diff where a direct isunsigned() call would have been appropriate –
I only checked for instances where the type clearly cannot be a pointer,
but chose to go the safe route in replicating existing behavior
otherwise).
Fixes DMD testcase 'traits'.
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.
Implementing the recursion in DeclarationExp::apply, which seems more
natural, lead to a "cannot interpret" CTFE error in Phobos.
An upstream bug will be raised about this.
Some files in our copy of the DMD 2 source had CRLF line endings.
This was not only inconsistent, but also made merging DMD patches
(where LF is used throughout) unnecessarily painful.
The Windows linker LINK insists on the .obj extension. The following changes are made:
- CMake uses the same extension as the C compiler
- global.obj_ext_alt (aka .obj) is recognized as objectfile extension
- global.obj_ext_alt is used on Windows
- 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.
