Running the compilers

The compilers use GNU’s assembler (as) and linker (ld) to transform generated assembly instructions into executables. For ease of use, the Makefile may also be used.

Testing was done on a Raspberry pi 2B, but you may change the target CPU (or FPU) in the Makefile. Both (p0 and p1) compilers generate ARM32 instructions.

Running the bootstrap compiler

Input/output is done using stdin/stdout, for which you can use pipes. For example:

bash

cat src/*.p0 | bin/p0 > bin/p1.s
as -mcpu=$CPU -mfpu=$FPU -o bin/p1.o bin/p1.s
ld -o bin/p1 bin/p1.o

Running the p1 compiler

The same applies for the p1 compiler.

bash

bin/p1 < test/src/helloworld.p1 > bin/test/helloworld.s

Makefile

The Makefile can be used for many things:

bash Bootstrapping the compilers

make all # compiles bin/p0, bin/p1 and the helper objects

bash Compiling one of the test programs

make bin/test/helloworld

bash Running one of the test programs

make helloworld

bash Running a test

make test/helloworld

bash Running all tests

make test

bash Deleting the binaries

make clean

bash Forcing a full recompilation

make clean all
# or
make clean test
# ...
