Previously, it could happen that regular symbols referenced
only as part of a template instance (e.g. a lambda passed as
an alias parameter) were not even emitted in the wrong module,
but not at all because mustDefineSymbol would return false to
them when being analyzed during codegen of the wrong module.
This issue might affect incremental compilation with DMD as
well, and the fix should be discussed with the upstream devs.
GitHub: Fixes#249.
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
- Moved main() into its own file gen/main.cpp
- Fixed basic cross compilation
- removed the option for setting OS
- added support for llc's mattr, mcpu and mtriple switches
- added basic ABI abstraction for return value rewrites, it's not perfect and will probably be completely rewritten once I get to handling parameter rewrites as well.
- x86-64 extern(C) abi for cfloat returns now match (llvm-)gcc.
