Some points off the top of my head… - I started out just printing strings, but found I wanted a bit more structure so I wrote a dozen or so functions to do the printing. Things at the level of call name,rags. All make a single line of IR. It helps keep the typos down. It took me about 8 hours to get enough that I have line number information and LLDB will show me functions and source lines on a backtrace. I should have done this much earlier than I did. I was getting by with line number comments in my IR, which is simple, but useless if you Give yourself an access violation. This will let you sort out how to do things. Screw that. The first may not be what you think it is, learn what it is. The second is just part of the magic of SSA. Highly recommend this.

Please see the Target-Specific Features and Limitations section for more details.

This page gives you the shortest path to checking out Clang and demos a few options. This should get you up and running with the minimum of muss and fuss. If you like what you see, please consider getting involved with the Clang community. If you run into problems, please file bugs on the LLVM bug tracker. Clang is released as part of regular LLVM releases. From Xcode 4.

Terminology and Notation. Optional Configuration Items. The LLVM project has multiple components. This contains all of the tools, libraries, and header files needed to process intermediate representations and converts it into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer. It also contains basic regression tests. C-like languages use the Clang front end. To save storage and speed-up the checkout time, you may want to do a shallow clone. For example, to get the latest revision of the LLVM project, use. Ninja — for generating Ninja build files.

PowerPC 32bit is still missing certain features e. No warnings will be produced from the location of the pragma onwards within the same file. Excess precision arithmetic can improve the accuracy of results although not always , and it can make computation significantly faster if the target lacks direct hardware support for arithmetic in a particular type. When targeting Thin LTO, the base is derived from the output filename, and the extension is not dropped. FMAs : fast fuses across statements disregarding pragmas on only fuses in the same statement unless dictated by pragmas off never fuses fast-honor-pragmas fuses across statements unless dictated by pragmas. On Linux, you may need GCC runtime libraries e. This might reduce the compilation speed marginally but many declarations from the OpenCL standard will not be accessible. Warn about unqualified uses of a member template whose name resolves to another template at the location of the use. The first may not be what you think it is, learn what it is. The visibility for dllexport definitions. TOC data transformation is off by default -mno-tocdata. This category is intended to make it possible to triage builds that produce a large number of errors or warnings in a grouped way.

For example, this will only instrument files finishing with. Use -pedantic-errors to request an error if a feature from a later standard revision is used in an earlier mode. These libraries are distributed alongside Clang in the library resource directory. Testing Time: This head sample count provides an indicator of how frequently the function is invoked. Form fused FP ops e. Otherwise, treat callsites without profile samples as if we have no profile. This is used for generating Visual Studio solution and project files. These environment variables are handy when you need to request the statistics report without changing your build scripts or alter the existing set of compiler options. For CMake builds e.
