+# Compiler
+
+- Catch exceptions thrown by the argument parser and print them normally.
+- Structs or records.
+- Unions.
+- Type checking.
+- Support immediates greater than 12 bits.
+- It seems instructions are correctly encoded only if the compiler is running
+  on a little endian architecture.
+- Assignment to a pointer.
+- Static array.
+- Syscalls.
+- Error message with an empty file wrongly says that a ")" is expected.
+- Support any expressions for constants.
+- Built-in types are added in the symbol table constructor. It would be better to
+  add them outside, before the type analysis begins.
