- Update to 1.15.0
* Big news
- Frontend, druntime and Phobos are at version 2.085.1, incl. new
command-line options -preview, -revert, -checkaction=context,
-verrors-context and -extern-std. (#3003, #3039, #3053) (new)
+ The Objective-C improvements from DMD 2.085 are not implemented
(#3007)
- Support for LLVM 8.0. The prebuilt packages have been upgraded to
LLVM 8.0.0 and include the Khronos SPIRV-LLVM-Translator, so that
dcompute can now emit OpenCL too. (#3005)
- Compiler memory requirements can now be reduced via the new -lowmem
switch, which enables the garbage collector for the front-end and
sacrifices compile times for less required memory. In some cases, the
overall max process memory can be reduced by more than 60%; see #2916
(comment) for some numbers. (#2916)
+ Note for package maintainers: this feature requires a recent D host
compiler (most notably, it doesn't work with ltsmaster), ideally
LDC 1.15 itself due to important GC memory overhead improvements in
2.085 druntime.
- Support for generic @llvmAttr("name") parameter UDAs, incl. new
@restrict with C-like semantics. (#3043) (new)
- macOS: 32-bit support was dropped in the sense of not being CI-tested
anymore and the prebuilt macOS package now containing x86_64 libraries
only. MACOSX_DEPLOYMENT_TARGET for the prebuilt package has been raised
from 10.8 to 10.9.
- Prebuilt packages don't depend on libtinfo and libedit anymore.
(#1827, #3019)
- x86: SSSE3 isn't required for the prebuilt packages and generated
optimized binaries anymore. (#3045) (new)
* Platform support
- Supports LLVM 3.9 - 8.0.
* Bug fixes
- Implicit cross-module-inlining of functions annotated with
pragma(inline, true) without explicit -enable-cross-module-inlining has
been restored. (#2552, #3014)
- Propagate well-known length of newly allocated dynamic arrays for
better optimizability. (#3041, #3042) (new)
- JIT: Support implicit __chkstk calls for Windows targets, e.g., for
large stack allocations. (#3051) (new)
- Update so_version to 85
