Show HN: xocc – C compiler based on BSD license Hello everybody, I'm glad to announce the major release of xocc C compiler, 1.2.1, based on BSD license. xocc is a C compiler that based on XOC infrastructure, XGEN code generator and XOCFE C frontend. Both xocc, XOC, XGEN, and XOCFE are based on BSD license. XOC provides multi-level IRs, flexibility, and the capability of representing almost all popular languages. There are mainly two level IRs used throughout all phases of the compilation. In addition to basic IR, XOC also provides IR builder, BB manipulating api, Control Flow Graph(CFG), IR lowering, Control Dependent Graph, Dominator Tree, Register SSA, Memory SSA, Agressive Flow Sensitive Alias Analysis, Flow Insensitive Alias Analysis, Agressive Field Sensitive Alias Analysis, Interprocedual Analysis Framework, Inliner, Dead Code Elimination, Copy Propagation, GCSE, GVN, and a lot of sophisticated control flow and peephole optimizations. Moveover, XOC does not use any std library, it provides all basic algorithm library such Vector, List, Map, Dense Bitset, Sparse Bitset, Graph, Mempool, Big-Integer, Linear Algebraic library, Linear Programming Solver, just read Manual.txt of XOC. XGEN provides a retargetable machine code generator. For now, it could generate ARM, x86 code. XGEN provides IR2OR translator, Instruction Scheduling, Register Allocation, Instruction Packager, Assembly. XOCFE is C frontend, it prints AST as output. XOCC is a driver that composes XOCFE, AST2IR, XOC and XGEN into complete C compiler. All features provided by XOCC, XOC, XGEN, XOCFE empower you developing any compiler and analysis tools. Any feedback on the compiler and its components would be much appreciated! To build xocc, see https://ift.tt/2JO3iU0 for details.

Show HN: Tape It, iOS recording app for musicians Hello HN, Over the last 15 months, two friends and I developed the music recording app we felt we wanted based on our own needs as musicians. It's called Tape It [1] and has just recently hit the Apple App Store [2]. We put a lot of effort into a good UX to help musicians really focus on playing their instrument instead of pretending to be a recording engineer. The app records in stereo on newer iPhones (although that's a premium feature; the free version only records in standard mono audio quality). I would be really grateful for advice from this community on how to best approach marketing. We had a great TechCrunch article covering our launch [3], and we posted it on various music websites. Turns out advertising on Google or Apple Search is a dark art, though. We have some good ideas for developing a good social media presence, but they will take time. Please hit us with feedback, opinions and advice that you think a young ind...
