Version 0.8.5

0.8.5 Change list

Changes / improvements

• Fetching MSVC also optionally fetches C/C++ headers for cross-compilation
• Experimental C backend.
• Allow the @section attribute on local static variables.
• Make $feat accept the same syntax as @feat.
• Added @asmname, which is similar to @cname but does not add any normal name-prefixing on targets where that is normal (such as MachO).
• Add --function-sections and --data-sections (function-sections / data-sections in project.json) to place each function or global variable in its own section, so the linker can discard unused ones #3051.
• Removed experimental support for cenum, faultset and distinct alternative names.
• Docs now use the constset, attrmacro and excuse.
• The static Linux binary now uses mimalloc for faster codegen and is aliased to c3-linux.tar.gz.

Fixes

• Regression for vec.pow(x).
• Macros with "const" declarations were compile time folded despite needing the declaration.
• Vectors created through casts in globals would miscompile, e.g. Foo global = { .v = (int[<3>])8 }.
• Support $$bswap for all power of two integers, including single bytes (in which case it is a no-op).
• Fix source locations for byte literal values continued on a new line.
• Faulty selection of subscript operator overload when calling method #3499
• Retain @nostrip on optimized code even if no use is found, static variables may now also have nostrip. #3500
• != overloads on structs behaved as == #3547.
• Multi-dimensional array comparisons on types with == overloaded would not compare.
• Lazy resolution of function pointer types could cause a segfault when unifying ternary types. #3552
• @swap now works with non-pure arguments.
• Incorrect lowering of vectors when created from designated initializers with zeroes at the end.

Stdlib changes

• Added std::gfx module.
• Added IntRect, IntVec2, IntVec3 and IntVec4 types.
• Updated organization of the MacOS / Darwin bindings, reorganized by framework, added many functions and split into std::os::darwin and std::os::macos, with among other things easy ObjC dispatch.
• Updated win32 bindings with many functions, reorganized by header.
• Cross-platform dylib handling with DylibHandle, os::dlopen, os::dlsym and related functions in std::os.
• Added Duration.to_sec
• Updated posix libc with shm_open, shm_unlink, truncate and ftruncate.
• Add NonNull and Nullable types for members with mandatory null checks.
• Cap durations and time to long::max/long::min with saturating maths.
• Added time::FOREVER_PAST, Time::diff_years, Time::diff_months, time::day, time::week, time::month, time::year.
• Added double.is_inf, float.is_inf.
