【日程安排】 [table] ,2015年11月21日（周六）中国科学院计算技术研究所 648会议室
14:00 – 14:30, 入场、签到 14:30 – 15:30, Clang内部实现，邢明杰 15:30 – 16:30, SDCC，史斌 16:30 - 17:00, 自由讨论 [/table]
题目：Clang内部实现 演讲者：邢明杰 简介：基于clang-3.5.0版本的代码，介绍下clang(http://clang.llvm.org/)的总体架构和各模块的实现，主要包括：驱动器（Driver），前端（Frontend），核心库（Lex，Parser，Sema，AST）。
题目: Introduction to SDCC - A light-weight cross-compile tool-chain targetting 8-bit MCUs 演讲者：史斌 简介: SDCC is a retargettable, optimizing ANSI - C compiler suite that targets the Intel MCS51 based microprocessors (8031, 8032, 8051, 8052, etc.), Maxim (formerly Dallas) DS80C390 variants, Freescale (formerly Motorola) HC08 based (hc08, s08), Zilog Z80 based MCUs (z80, z180, gbz80, Rabbit 2000/3000, Rabbit 3000A, TLCS-90) and STMicroelectronics STM8. Work is in progress on supporting the Microchip PIC16 and PIC18 targets. It can be retargeted for other microprocessors. It includes sdcpp (the preprocessor), sdcc (the compiler), sdas (the assembler), sdld (the linker), ucsim (the simlulator), and a lots of other useful components.
Ben Shi works for a private company as a technical manager. He joined SDCC community in Nov 2013 for filling his spare time, and has made 130+ commits since then, invloving bug fixes in the front end and assembly optimization for the STM8 back end. He will brief introduce SDCC features and his work on it.
