Clang C/C++ Download and Installation Instructions
Apr 14, · Our build system is using Clang not only as the compiler, but also as the front-end driver for a linker back-end. Unfortunately, Clang from NDK r11c can't properly determine the linker executable: android-ndk-r11c\toolchains\llvm\pre. Sep 02, · clang++: error: clang frontend command failed due to signal (use -v to see invocation) Android clang version (based on LLVM ) Target: x86_linux-gnu. LLVM Download Page The major changes and improvements that the development version contains relative to the previous release are listed in the Release Notes for the next release. These binaries include Clang, LLD, compiler-rt, various LLVM tools, etc. varying slightly between platforms.
Clang version 3.8.256229 download
Here we describe the status of Clang in some detail, including major improvements from clang version 3.8.256229 download previous release and new feature work. Some of the clang version 3.8.256229 download new features and improvements to Clang are listed here. The improvements since the 3. Clang supports tuning for three debuggers, as follows. Specifying -g without a tuning option will use a target-dependent default, clang version 3.8.256229 download.
The new -fstrict-vtable-pointers flag enables better devirtualization support experimental. Clang has gotten better at passing down strict type alignment information to LLVM, and several targets have gotten better at taking advantage of that information. Clang version 3.8.256229 download a pointer that is not adequately aligned for its type is undefined behavior.
It may crash on target architectures that strictly enforce alignment, but even on architectures that do not, frequent use of unaligned pointers may hurt the performance of the generated code. If you find yourself fixing a bug involving an inadequately aligned pointer, clang version 3.8.256229 download, you have several options.
The best option, when practical, is to increase the alignment of the memory. For example, this array is not guaranteed to be sufficiently aligned to store a pointer value:. If the pointer is to a struct that represents that layout of a serialized structure, consider making that struct packed; this will remove any implicit internal padding that the compiler might add to the struct and reduce its alignment requirement to 1.
You may also override the default alignment assumptions of a pointer by using a typedef with explicit alignment:. The final option is to copy the memory into something that is properly aligned.
Be aware, however, that Clang will assume that pointers are properly aligned for their type when you pass them to a clang version 3.8.256229 download function like memcpy. For example, this code will assume that the source and destination pointers are both properly aligned for an int:. You may explicitly disable this assumption by casting the argument to a less-aligned pointer type:.
Clang promises not to look through the explicit cast when inferring the alignment of this memcpy. Clang 3. OpenMP 3. The runtime can be built in-tree. In addition to OpenMP 3. We continue to aim to complete OpenMP 4. The codegen for OpenMP constructs was significantly improved allowing us to produce much more stable and fast code.
Full test cases of IR are also implemented. These are major API changes that have happened since the 3. If upgrading an external codebase that uses Clang as a library, this section should help get you past the largest hurdles of upgrading. The following matchers were affected:. The scan-build and scan-view tools will now be installed with Clang.
Use these tools to run the static analyzer on projects and view the produced results. A wide variety of additional information is available on the Clang web page. The web page contains versions of the API documentation which are up-to-date with the Subversion version of the source code.
If you have any questions or comments about Clang, please feel free to contact us via the mailing list. Pipe specifier was added although no pipe functions are clang version 3.8.256229 download yet. Improved vector support and diagnostics. Improved diagnostics for function pointers. Directive name modifiers for if clause [2.
With this release, the autoconf build system is deprecated. It will be removed in the 3. Please migrate to using CMake.
Several new checks were added: The analyzer now checks for misuse of vfork. The analyzer can now detect excessively-padded structs, clang version 3.8.256229 download. This check can be enabled by passing the following command to scan-build: -enable-checker optin. The analyzer now has opt in checks to detect localization errors in Cocoa applications.
The checks warn about uses of non-localized NSStrings passed to UI methods expecting localized strings and on NSLocalizedString macros that are missing the comment argument. These can be enabled by passing the following command to scan-build: -enable-checker optin, clang version 3.8.256229 download. Created using Sphinx 1.
