 Makefile

 A Makefile is a text file used with the GNU Make utility to automate the compilation process in GCC. It specifies the instructions for building an executable or library from your source code files.

This is like building a LEGO set. makefile takes all the different pieces and put them together. One of the benefits is when rebuilding makefile only update the part that need to. so it just switch out a small part of the LEGO set, no need to start from stretch. Reduce time of building a new version speed up developing time.

Project Stage 1

GCC install and build with version Before diving into the code, let's set up a local GCC installation. Head over to the official installation guide https://gcc.gnu.org/install/ for detailed instructions. Here's a quick rundown: Clone the Source: Use git clone git://gcc.gnu.org/git/gcc.git to grab the latest GCC source code. Build Directory: Create a directory "mkdir" for your build and navigate to it using "cd" . you can create different versions for different use case, but keep in mind GCC is not small. Once you are done with the build, you can simply delete the build files . We create different directory for different build so it would have a cleaner workflow. mkdir ./gcc-build-001 cd ./gcc-build-001 Local Installation: In your newly made build folder. Specify a custom installation path with "../configure --prefix=/path/to/install/gcc ". Replace "/path/to/install/gcc " with your desired location. This will create a make file fo...

Project Stage 2

 My task is: Command-line Parsing Description: Parse the GCC command line to pick up AFMV options, process the version list to validate the architectural feature specification. (example: -fafmv=var1,var2) One of the places to see how others did it is on GitHub of other class that did similar project task. I could also go on GCC's git to see pass commit that is could be related to my task of adding a pass. Most of my work will be done in the  .opt file writing. We will be using slack as a communication tool. Link: other class: https://github.com/seneca-cdot/gcc GCC: https://gcc.gnu.org/onlinedocs/gccint/ GitHub: https://github.com/seneca-cdot/gcc (I work in the branch " 2024-S-command-line-parsing ") GitHub branch: https://github.com/Seneca-CDOT/gcc/tree/2024-S-command-line-parsing I will be using the class server. I don think I want to spend time on trying to do it on my local device. This term of SPO600 they cut the time in half. We are very time limited. This stage we...
