• LLVM 3.7.x is now supported.
• Coverage Analysis à la DMD added. Implemented by Johan Engelen! (#878)
• std.net.curl now loads libcurl at runtime if/when it is actually used. This is the same fix present in post-2.068 DMD, and avoids linking issues.

Platform support:

• Win64 runtime now supports VS2015.
• Varargs fix & ABI refactoring. (#768) Thanks to kinke for the great work!

• ABI transformations are never applied for variadic arguments. (#172)
• stack trace missing on assert failure. (#115, fixed only on OS X, see #863)
• core.stdc.stdarg doesn't work on 64 bits. (#73)

Building LDC:

• CMake fails after git gc. (#874)
• Fix cmake bug when ldc is a submodule. (#860)
• druntime fails compilation with MinGW-x64. (#847)
• Now uses "REGEX REPLACE" for MSVC static libaries option.

Internals:

• The Travis-CI builds now use the docker environment.
• AppVeyor is used to check the Win64 build. Snapshots can be downloaded from https://ci.appveyor.com/project/kinke/ldc.
• Coverage Analysis for the LDC source code is now available at https://coveralls.io/r/ldc-developers/ldc. (#903, #380). Thanks a lot to Dmitri Makarov for implementing this!
• The CPP mangler calls now fatal() instead of assert(0) in many places. (#927, #928, #929)

• Modernize bash completion setup. (#840)
• Updates to Travis-CI: gcc 4.9 and LLVM 3.7 are added. (#838)
• ldc2: valgrind: invalid read of size 4. (#825)

Known issues:

• LDC does not zero the padding area of a real variable. This may lead to wrong results if the padding area is also considered. See #770. Does not apply to real members inside structs etc.
• atomicLoad(), atomicStore() et al. with 128bit data requires an alignment of 16 bytes on x86-64. Add align(16) if you encounter a segfault. If you are using vibe.d then you need to use version ~master because of this.
• Phobos does not compile on MinGW platform.

LDC 0.14.0

(Changes from alpha-1 release are marked with (new) and gone.)

Big news:

• Frontend, druntime and Phobos are at version 2.065.0.
• Building druntime/Phobos as shared libraries on Linux is now supported, but not enabled by default. Use -DBUILD_SHARED_LIBS=ON on the CMake command line to enable shared libraries.
• On Linux, link-time stripping of dead code (--gc-sections) is now usable and enabled by default. Try -disable-linker-strip-dead in case of mysterious linker issues/runtime crashes, as such problems might be caused by related issues (for example in third-party C libraries).
• The deprecated -noruntime switch is now removed. The -nogc switch now also shows a line number in the error message.
• LLVM intrinsics llvm.bswap.i#, llvm.ctpop.i#, llvm.ctlz.i# and llvm.cttz.i# are now builtins and can be used with CTFE. (#648) (new)
• Deprecated version identifiers have been removed.
• Deprecated pragma names have been removed.
• An experimental switch -template-depth to control the maximum number of nested template instantiations has been added.

Platform support:

• The architectures ppc64le, amd64, amd64_be and armbe are available if built with LLVM 3.5.
• Some code for ARM and MIPS64 has been added.
• Support for LLVM 3.5 has been added.

Bug fixes:

• The shared libraries implementation fixes a couple of known issues. (#433, #291, #239, #194, #228)
• Fixed a problem in constructing a char representation of a type which resulted in an ICE. (#642)
• ldmd2: -defaultlib= works now. (#601)
• The -defaultlib/-debuglib was reworked including split between druntime and Phobos. (#416)
• Returning value transitively through assignment now works. (#629)
• A purity issue was fixed. (#575)
• GC spends too much time in marking phase. (#233)
• Avoid invalid *&ex -> ex optimizations. (Backport of a DMD regression) (#649)
• A missed optimization is fixed now. (#338)
• pragma(LDC_no_moduleinfo) now disables generation of module metadata. (#571)
• Fixed the signature of intrinsic llvm.prefetch and added new intrinsic llvm.clear_cache (from LLVM 3.5). (new)

Building LDC:

• The build does not break if variable LLVM_LDFLAGS contains a newline. (#691)
• A missing va_end was added. (#695) (new)
• The Win64 build was improved. It requires at least VS2012 and must be build against LLVM 3.5 with this patch from Twobit applied.

Internals:

• Some rarely used LLVM-internal switches are now hidden from command line -help. Use -help-hidden to display all of them.

Known regressions:

• LDC emits too much code. This leads to spurious failures in the std.stdiobase unit test. Workaround is adding -lcurl to the commandline. (This seems to be related to #662.)

• Avoid invalid *&ex -> ex optimizations. (Backport of a DMD regression) (#649)
• A missed optimization is fixed now. (#338)
• pragma(LDC_no_moduleinfo) now disables generation of module metadata. (#571)

Building LDC:

• The build does not break if variable LLVM_LDFLAGS contains a newline. (#691)
• The Win64 build was improved. It requires at least VS2012 and must be build against LLVM 3.5 with this patch from Twobit applied.

Internals:

• Some LLVM-internal switches are now hidden to clear up the command line -help. Use -help-hidden to display all of them.

Known regressions:

• LDC emits too much code. This leads to spurious failures in the std.stdiobase unit test. Workaround is adding -lcurl to the commandline. (This seems to be related to #662.)
• Using nested structs with AAs can trigger an erroneous "cannot create associative array" error in some very specific circumstances (#407).
• Garbage collection does not work on Linux/PPC64 and other big-endian systems.

LDC 0.13.0

(Changes from beta-1 release are marked with (new) and gone.)

Big news:

• Frontend, druntime and Phobos are at version 2.064.2. Building druntime/Phobos as shared libraries is not supported yet, but will likely be in the next 2.065-based release. The new DSO infrastructure to support shared libraries is already implemented.
• Because of the new DSO infrastructure, the -noruntime switch is no longer supported. Now every module calls the runtime during initialization. Instead a new -nogc switch is introduced which warns about implicit GC calls. The -noruntime switch is still parsed but has no functionality and will be removed in next major version 0.14.0.

Platform support:

• A version identifier for Android has been added. Druntime/Phobos support is missing.
• A version identifier for NVPTX/NVPTX64 has been added.
• The architecture AArch64_be is available if built with LLVM 3.5.
• The version identifier for the used float ABI is now derived from the command line and default target value. It also defines the version identifier for the architecture (e.g. PPC_HardFloat).
• Version identifiers for the various MIPS ABIs have been added.

Bug fixes:

• The format failure on MingW32 is fixed. (#383)
• Fixed yet another compiler crash with vector types. (#424)
• LDC generates segfaulting code with nested functions. (#513)
• Added check to ensure that types from object.di exist before using them. (#551)
• Do not emit bounds check code if the index is statically known to be within bounds. (#553)
• It is again possible to compile druntime/Phobos with MSVC-built LDC. (#570)
• LDC can now be build with MSVC in release mode. (#458)
• __MODULE__ does not crash LDC. (#446)
• LDC does not crash if using triple arm7-apple-darwin. (Reported in forum.)
• The vectorization passes are now enabled if LLVM 3.4/3.5 is used. (Reported in forum.)
• The option -disable-simplify-libcalls is available for LLVM 3.4+, too.
• Option -lib of ldmd creates a library with an object per module. (#579)
• LDC builds on FreeBSD 10. (#584)
• The config file is now also searched in the current directory. (#589)
• Fixed ICE with extern(C) struct with ctor and field. (#624) new
• Some code emission fixes. new

Building LDC:

• LLVM 3.4.x is now supported.
• First changes for LLVM 3.5 are incorporated.
• The assembler file core/threadasm.S is excluded from the build if the CMake version is less than 2.8.5. This prevents a bunch of error messages. The assembler file is only required for non-x86 platforms. If you get linking errors on non-x86 platforms please consider upgrading your CMake installation. (#464)
• LDC builds with -std=c++11. (#330)
• LDC builds on OS X Mavericks. (#544)
• LDC builds on FreeBSD 10. (#584)
• LDC builds on Solaris/x86 (compiler only, druntime/Phobos support missing)
• The unresolved symbols during linking of release build of unit test std.uni are gone. (#594)

Internals:

• LDC can now generate code instrumented for the address sanitizer, memory sanitizer and thread sanitizer. This requires clang to be used as linker. This is still experimental. You must link against gcstub.o in order to use the address sanitizer. It is recommened to built an instrumented version of druntime/Phobos before using this feature.
• With LLVM 3.4 or later LDC generates llvm.ident metadata to identify object files as created by LDC.
• Verbose output (-v) now prints the path to LDC binary and version information. Also all defined version identifiers are printed.

Known regressions:

• LDC emits too much code. This leads to spurious failures in the std.stdiobase unit test. Workaround is adding -lcurl to the commandline.
• Using nested structs with AAs can trigger an erroneous "cannot create associative array" error in some very specific circumstances (#407).
• Garbage collection does not work on Linux/PPC64.
