Tiny

A toy C compiler

Building Tiny

Build Tiny using make, or with the following commands:

flex lexer.l
bison -d parser.y
gcc lex.yy.c parser.tab.c symtab.c ast.c main.c -o tiny -Wall

Usage

You can use Tiny to produce executables using make as follows:

./tiny /path/to/prog.c
make target

Note that if you use the make method, your executable will be called out. Alternatively, you can manually produce programs using Tiny as follows:

./tiny /path/to/prog.c
as out.s -o out.o
ld -s -o <executable_name> out.o

In addition to compiling source files, if you invoke Tiny with no arguments, you can enter the source program from the command line.

For example:

./tiny
int main() {
  exit(2);
}

will produce the following assembly in out.s:

.text
  .global _start

_start:
  movl  $1, %eax
  movl  $2, %ebx
  int   $0x80
