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
|
||
|
|
```
