Clang on Windows
LLVM-MinGW
- Get packages from https://github.com/mstorsjo/llvm-mingw
The best port of LLVM/Clang on Windows I tried.
- No dependency on Visual Studio.
- Support 32-bit and 64-bit targets.
- Support sanitizers (ASAN, UBSAN).
MSYS2
MSYS2 now provides clang 9.0 packages.
- No dependency on Visual Studio.
- Support 32-bit and 64-bit targets.
- But does not support sanitizers (ASAN, UBSAN).
Official LLVM
Packages from the official LLVM at http://releases.llvm.org/download.html.
- DEPEND on Visual Studio for linking
- Support 32-bit and 64-bit targets.
- (Maybe) support sanitizers (ASAN, UBSAN).
Tips
Get Stack Pointer
Use this macro [1]:
#define current_stack_pointer ({ \
register unsigned long esp asm("esp"); \
asm("" : "=r"(esp)); \
esp; \
})
Turn errors into warning
-Wno-error=foo Turn warning “foo” into an warning even if -Werror is specified.
Enable all warnings: -Weverything
-Weverything means enable all current and future warnings. See Better Apps with Clang's Weverything or Wall is a Lie!
