with following code, can generate llvm bitcode file module: llvm::module * module; // fill module code module = ...; std::error_code ec; llvm::raw_fd_ostream out("anonymous.bc", ec, llvm::sys::fs::f_none); llvm::writebitcodetofile(module, out); i can use bitcode file generate executable machine code file, e.g.: clang -o anonymous anonymous.bc alternatively: llc anonymous.bc gcc -o anonymous anonymous.s my question is: can generate machine code directly in c++ llvm api without first needing write bitcode file? i looking either a code example or @ least starting points in llvm api, e.g. classes use, nudging me in right direction might enough. take @ llc tool source , spcifically compilemodule() function. in short, creates target , sets options via targetoptions , uses addpassestoemitfile() , asks passmanager perform planned tasks.

i trying write basic program work this: enter name: _ enter age: _ name <name> , age <age>. i've been trying figure out how in node without using prompt npm module. my attempt @ was: import readline 'readline' const rl = readline.createinterface({ input: process.stdin, output: process.stdout }) rl.question('what name? ', (name) => { rl.question('what age? ', (age) => { console.log(`your name ${name} , age ${age}`) }) }) however, nested way of doing seems weird, there anyway can without making nested right order? zangw's answer sufficient, think can make clearer: import readline 'readline' const rl = readline.createinterface({ input: process.stdin, output: process.stdout }) function askname() { return new promise((resolve) => { rl.question('what name?

i given question in algorithm class is 2^{2n} upper bounded o(3^n)? now clear 2^2n 4^n, , 4^n can't upper bounded 3^n. however if take log on both sides on lhs 2n on rhs kn (where k constant) 2n can upper bounded kn, contradicting of more obvious claim above. doing wrong in reasoning? essentially, reasoning boils down statement: if log f(n) ≤ c log g(n) constant c, f(n) = o(g(n)). this statement isn't in general true statement, though. 1 way see find counterexamples: if f(n) = n 4 , g(n) = n, log f(n) = 4 log n , log g(n) = log n. it's true there's multiple of log n that's bigger 4 log n, n 4 ≠ o(n). if f(n) = 4 n , g(n) = 2 n , log f(n) = 2n , log g(n) = n. there's multiple of n makes bigger 2n, 4 n ≠ o(2 n ). to @ why doesn't work, notice c log g(n) = log g(n) c , multiplying log constant equivalent raising original function large power. can reason big-o of function multiplying constant, can't reason raising p...

case in point: the facebook https://graph.facebook.com/oauth/access_token endpoint, in handing off code access token, returns access_token , expires . instagram seems same. on other hand, twitter https://api.twitter.com/oauth/access_token returns both access_token , access_token secret . subsequently, when accessing facebook api endpoints, send access_token request. on other hand, accessing twitter endpoints requires signing request secret well. the reason ask: i'm implementing own oauth web app api, , make sure conform standards. designed act twitter, don't understand why facebook & instagram act in way do. facebook , instagram use oauth 2.0 protocol whereas twitter uses oauth 1.0a protocol. posts here , here may understand differences.

i have column name remainingdays. counts remaining days since last donation of user. how can auto decrement column daily. example column has value of 90 tommorow becomes 99. automatically updates database without users interaction. i add date field database. each time donation made, update date , reset counter. then whenever need check or current value of counter, change select using to_days function in mysql converts date number-of-days value. select current_count - to_days(now())-to_days(date(last_donation)) result so if last update made yesterday, counter value reset beginning , yesterdays date have been recorded. if value set 100, today when select return 99 , in ten days return 90. this how i'd anyway , assumes mysql i'm sure type of functionality available in sql database sever environments.
