Now, I know what you might be thinking: “But why would anyone want to save space with a compiler? Isn’t that like trying to fit an elephant in a shoe box?” Well, bro, let me explain.

First, the benefits of optimizing GCC for space saving. As you may know, compilers can generate large output files due to their complex nature and various optimization techniques. However, by reducing the size of these output files, we can save valuable disk space on our systems. This is especially important in environments where storage capacity is limited or expensive, such as embedded devices or cloud computing platforms.

But how do we go about optimizing GCC for space saving? Well, there are a few tricks that you might find useful:

1. Use the -Os flag to enable size optimization instead of speed optimization (-O2). This will result in smaller output files at the expense of slightly slower compilation times.

2. Disable unnecessary features and options using the -disable-* or –without-* flags, such as debugging symbols (-g) or profiling information (-pg). These can significantly increase the size of your output files without providing any real benefit in most cases.

3. Use a smaller target architecture by specifying it with the -march flag. For example, using -marm instead of -mnative will result in smaller output files for ARM-based systems.

4. Enable linker optimization using the –gc-sections or -Wl,-s flags to remove unused sections from your final executable. This can significantly reduce its size without affecting its functionality.

Now, debugging with GCC. As you may know, compilers generate intermediate code that is easier for humans to read and understand than machine language. However, this intermediate code can also be useful for debugging purposes by allowing us to see how the compiler translates our source code into executable instructions.

To enable debugging in GCC, we simply need to use the -g flag when compiling our source files. This will generate debug information that can be used with various tools and utilities, such as gdb or valgrind. However, as mentioned earlier, this can significantly increase the size of your output files without providing any real benefit in most cases.

To avoid this issue, we can use a technique called “stripping” to remove unnecessary debug information from our final executable using the –strip-all flag with the linker or ld command. This will result in smaller output files that are easier to distribute and share without sacrificing functionality or performance.
