A toy language compiler.

Build dependencies

• ANTLR4
• Meson
• Ninja
• C++ compiler

Runtime dependencies

• ANTLR4 C++ runtime
• QBE
• Assembler (the one in the C compiler will do)

Build steps

meson setup builddir
ninja -C builddir

The xc binary is in builddir/bootstrap/xc. Optionally install it with

ninja -C builddir install

Usage

Use xc to compile xlang to QBE intermediate langage

xc -o foo.ssa foo.x

Use qbe to optimize and emit assembly

qbe -o foo.S foo.ssa

Assemble and link the binary (easiest to let the C compiler figure it out)

cc -o foo foo.S
