chibicc_arm64

C compiler on M1 Mac.

Prerequisites

Before building the compiler, ensure you have the following installed on your M1 Mac:

• CMake
• Xcode
  • Xcode is specifically required for M1 Mac users. Install Xcode from the App Store or by running xcode-select --install in your terminal.

Note: This compiler is designed to work exclusively on M1 Macs and may not function correctly on other platforms.

Build

$ cmake -S . -B build
$ cmake --build build

Generated files:

• build/chibicc : C compiler
• build/chibicc2 : C compiler (stage 2)
• build/chibicc3 : C compiler (stage 3)

Stage 3 compiler (chibicc3) is verified to match the stage 2 compiler (chibicc2) in output, ensuring the correctness of the bootstrapping process.

Run

$ ./build/chibicc -S -o tmp.s tmp.c
$ clang -o tmp tmp.s
$ ./tmp

Usage:

• -o <file> : Output file name
• -S : Generate assembly code
• -c : Generate object file
• -E : Generate preprocessed code
• -I <dir> : Add include path

Test

$ cd build
$ ctest

Running the tests will help ensure that your build is functioning correctly and that any changes made have not introduced regressions.

Todo

• function that take 9 or more arguments
• preprocesser : __attribute__, __asm, __has_include
• designated initializer
