The Compilation Toolchain Cross-Compilation for Embedded Systems Prof. Andrea Marongiu ([email protected]) Toolchain The toolchain is a set of development tools used in association with source code or binaries generated from the source code • Enables development in a programming language (e.g., C/C++) • It is used for a lot of operations such as a) Compilation b) Preparing Libraries Most common toolchain is the c) Reading a binary file (or part of it) GNU toolchain which is part of d) Debugging the GNU project • Normally it contains a) Compiler : Generate object files from source code files b) Linker: Link object files together to build a binary file c) Library Archiver: To group a set of object files into a library file d) Debugger: To debug the binary file while running e) And other tools The GNU Toolchain GNU (GNU’s Not Unix) The GNU toolchain has played a vital role in the development of the Linux kernel, BSD, and software for embedded systems. The GNU project produced a set of programming tools. Parts of the toolchain we will use are: -gcc: (GNU Compiler Collection): suite of compilers for many programming languages -binutils: Suite of tools including linker (ld), assembler (gas) -gdb: Code debugging tool -libc: Subset of standard C library (assuming a C compiler). -bash: free Unix shell (Bourne-again shell). Default shell on GNU/Linux systems and Mac OSX. Also ported to Microsoft Windows. -make: automation tool for compilation and build Program development tools The process of converting source code to an executable binary image requires several steps, each with its own tool. -

Atomicity and Visibility in Tiny Embedded Systems
Atomicity and Visibility in Tiny Embedded Systems John Regehr Nathan Cooprider David Gay University of Utah, School of Computing Intel Research Berkeley {regehr, coop}@cs.utah.edu [email protected] Abstract bool flag = false; // interrupt handler Visibility is a property of a programming language’s void __vector_5 (void) memory model that determines when values stored by { one concurrent computation become visible to other atomic flag = true; computations. Our work exploits the insight that in } nesC, a C-like language with explicit atomicity, the traditional way of ensuring timely visibility—volatile void wait_for_interrupt(void) variables—can be entirely avoided. This is advan- { tageous because the volatile qualifier is a notorious bool done = false; do { source of programming errors and misunderstandings. atomic if (!flag) done = true; Furthermore, the volatile qualifier hurts performance } while (!done); by inhibiting many more optimizations than are neces- } sary to ensure visibility. In this paper we extend the semantics of nesC’s atomic statements to include a visi- bility guarantee, we show two ways that these semantics Figure 1. nesC code containing a visibility er- can be implemented, and we also show that our better ror implementation has no drawbacks in terms of resource usage.

Shell commands are prefixed by a “$” prompt. Due to time constraints, we will not be building everything from source in real-time. - Binaries have been prepared for you in the VM image. - Detailed build steps are documented here for completeness but are not necessary if using the VM. Interactive portions of this tutorial are denoted with: $ echo 'Hello world' . Also as a reminder, these slides are marked with an icon in the upper-right corner: 3 Software Stack .

It is available at http://www.gnu.org/software/binutils/. * GNU Compiler Collection (GCC): These are the compilers for C and other languages which, depending on the version of GCC, include C++, Objective-C, Objective-C++, Java, Fortran, Ada, and Go. They all use a common back-end which produces assembler code which is fed to the GNU assembler. It is available at http://gcc.gnu.org/. * C library: A standardized API based on the POSIX specification which is the principle interface to the operating system kernel from applications. There are several C libraries to consider, see the following section. [1. Toolchain]$ _ [4/19] >>> C library * glibc: Available at http://www.gnu.org/software/libc. It is the standard GNU C library. It is big and, until recently, not very configurable, but it is the most complete implementation of the POSIX API. * eglibc: Available at http://www.eglibc.org/home. -
