package gccjit

Create a block. You can give it a meaningful name, which may show up in dumps of the internal representation, and in error messages.

Which function is this block within?

Add evaluation of an rvalue, discarding the result (e.g. a function call that returns void). This is equivalent to this C code:

(void)expression;

Add evaluation of an rvalue, assigning the result to the given lvalue. This is roughly equivalent to this C code:

lvalue = rvalue;

Add evaluation of an rvalue, using the result to modify an lvalue. This is analogous to "+=" and friends:

lvalue += rvalue;
lvalue *= rvalue;
lvalue /= rvalue;
etc

For example:

(* "i++" *)
add_assignment_op loop_body i Plus (one ctx int_type)

Add a no-op textual comment to the internal representation of the code. It will be optimized away, but will be visible in the dumps seen via Dump_initial_tree and Dump_initial_gimple and thus may be of use when debugging how your project's internal representation gets converted to the libgccjit IR.

Terminate a block by adding evaluation of an rvalue, branching on the result to the appropriate successor block. This is roughly equivalent to this C code:

if (boolval)
  goto on_true;
else
  goto on_false;

Terminate a block by adding a jump to the given target block. This is roughly equivalent to this C code:

goto target;

Terminate a block by adding evaluation of an rvalue, returning the value. This is roughly equivalent to this C code:

return expression;

Terminate a block by adding a valueless return, for use within a function with void return type. This is equivalent to this C code:

return;
