2011-10-11Print transformtions sorted on the name of the first instructionBjörn Gustavsson
2011-10-11Share code for call of predicate and transformation functionsBjörn Gustavsson
2011-10-11Simplify transformations of gc_bif[123] instructionsBjörn Gustavsson
Each gc_bif[123] instruction must have both a transformation in ops.tab and special code in gen_guard_bif[123](). Rewrite it to do most of the work in gen_guard_bif[123]().
2011-10-11Refactor 'too_old_compiler' handlingBjörn Gustavsson
In the handling of generic instructions, we used to always test whether the instruction was 'too_old_compiler' and abort loading with a special error message. Refactor the code so that we only do test if we an error has occurred. That will allow us to make the test more expensive in the future, allowing us to customize error messages for certain opcode without any cost in the successful case.
2011-10-11Introduce 'try_me_else_fail'Björn Gustavsson
2011-10-11Combine 'store_var' with 'next_arg'Björn Gustavsson
'store_var' is always followed by 'next_arg'.
2011-10-11Merge 'next_instr' and 'is_op' into 'next_instr'Björn Gustavsson
'next_instr' is always followed by 'is_op'.
2011-10-11Merge 'new_instr' and 'store_op' into 'new_instr'Björn Gustavsson
Since the 'new_instr' instruction always occurs before the 'store_op' instruction, we can merge the instructions into one. Also, there is no need to include the arity of the BEAM instruction as an operand, since the arity can be looked up based on the opcode.
2011-10-11Combine a 'call' instruction with the following 'end' instructionBjörn Gustavsson
A 'call' instruction in the loader transformation language is always followed by an 'end' instruction, so we can replace the 'call' instruction with a 'call_end' instruction.
2011-10-11Remove some unnecessary type constraints in transformationsBjörn Gustavsson
We don't need type constraints that essentially are assertions; the wrong type will be detected and loading aborted when no specific instruction can be found.
2011-10-11Get rid of redundant 'try_me_else' and 'fail' instructionsBjörn Gustavsson
If the left part of a transformation will always match, omit the the 'try_me_else' and 'fail' instructions. As part of this optimization, make it an error to have a transformation that can never be reached because of a previous transformation that will always match. (Remove one transformation from ops.tab that was found to be unreachable.)
2011-10-11Add some more information in instruction commentsBjörn Gustavsson
2011-10-11In transformations, don't store variables that are never usedBjörn Gustavsson
This optimization will save some space (in the loader tables) and some loading time.
2011-10-11Remove redundant 'next_arg' before 'next_instr'Björn Gustavsson
Fix the incorrect code that attempted to remove a single 'next_arg' instructions before 'next_instr'.
2011-10-11Generalize and rename is_set_var_instr() to is_instr()Björn Gustavsson
It is more useful to have a helper function that can test for any instruction.
2011-10-11Remove too_old_compiler handling for very old instruction variantsBjörn Gustavsson
is_list/2 and other test instructions with a zero label was last generated by the v1 BEAM compiler which was last supported in R6B. Since BEAM modules produced by that compiler will be rejected with a nice error message for other reasons (e.g. by the test for the module_info/0,1 functions), retaining those transformations serves no useful purpose.
2011-10-11Remove the special instructions for the hybrid heap emulatorBjörn Gustavsson
The hybrid-heap emulator is broken since R12, so there is no need to keep those instructions.
2011-10-11Remove optimization of 'move R R'Björn Gustavsson
Ancient versions of BEAM compiler could generate move instruction with the same source and destination registers, so the loader would optimize away such instructions.

2011-09-26erl_prim_loader: Eliminate dialyzer warningBjörn Gustavsson
The concat/1 function is now only used to append lists when constructing filenames. Thus it is too general and the first clause (that handles characters) will never be used. We could just remove the clause that is never used, but then the name 'concat' would be misleading and someone could use misuse it. Therefore, replace concat/1 with the join/2 function that can only be used for joining filename components.
