c++ - Static code generation using the LLVM API -


starting llvm module *mod containing ir: how use specific back-end generate target-specific assembler it? unfortunately kaleidoscope tutorial not detail on this. uses execution engine jit compile program (on build, target architecture), not select specific back-end generate target-specific assembler. neither llvm tutorials, not detailing on building static compiler, assume. thus, question can provide missing piece of information.

since want build static compiler, don't want use command line tools llc, etc. accomplish job. want use llvm api.

to make more concrete, let's start code:

llvmcontext &context = getglobalcontext(); smdiagnostic err; module *mod = parseirfile(argv[1], err, context);

the filename (given 1st argument) parsed ir. let's skip optimization passes , create assembler specific back-end, e.g. ptx backend (available since version 3.2).

just in source code of tools/llc/llc.cpp. that, , it's pretty short , not hard understand. if have specific questions things don't understand, feel free ask.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
