Where can I find what C++ API correspond to what llvm commands? [closed]












0














What is a general way to look at LLVM and find the corresponding calls in the C++ API?
For example, I have the logical and instruction which corresponds to the Language reference here.
How can I find a corresponding C++ API reference? My general approach would be to put "llvm add instruction C++ API" into a search engine, but this isn't consistently useful.

Usually for an someinst instruction there is a SomeInstInst class. For instance, alloca is implemented by AllocaInst.



But not for add, that's what confused you. Binary arithmetic and logical instructions are implemented using single class called BinaryOperator.



Another exception is a phi instruction - it is implemented in the PHINode class. Other than that, figuring what class you need should be pretty straightforward.

  • As a follow-up, given a function call, say CreateNUW, is there some textual documentation for me to find out what a function does without reading the function definition's source code?

    If there is no documentation in Doxygen, then no, I think. But such functions are mostly self-explanatory.

count number of partitions of a set with n elements into k subsets

up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
