2011-01-17beam_emu: Don't inline helper functions into process_main()Björn Gustavsson
By default, GCC will inline calls to helper functions. Since process_main() is already huge, there is no reason to inline the helper functions (and some of them are used very seldom).
2011-01-17beam_emu: Clean up calling of the error_handler moduleBjörn Gustavsson
There were two separate functions (call_error_handler() and call_breakpoint_handler()) that were identical except for the name of the function in the error_handler module being called. Generalize call_error_handler() by adding a function name argument so that it can be used for both purposes. Also let the call_error_handler() return the new program counter instead of passing it in c_p->i. That slightly decrease the code size at the call site. There is also no need to use the Dispatch() macro to yet again decrease the reduction counter, because that has just been done by the call instruction that caused the execution of the call_error_handler or i_debug_breakpoint instruction.
2011-01-17Simplify a select_val instruction that selects only one valueBjörn Gustavsson
The compiler does not generate select_val instructions that only selects one value, but the loader may previously have created such an instruction when it splitted a select_val instruction that selected on bignums.
2011-01-17Optimize creation of tuplesBjörn Gustavsson
Combine the put_tuple/2 and all following put/1 instructions to one i_put_tuple/2 instruction. In general, that will reduce the number of instruction words by 50 percent. Measurements seem to indicate that the speed is about the same.
2011-01-17beam_makeops: Support jumping to common code from an instruction macroBjörn Gustavsson
2011-01-17beam_load: Run the packing engine before loading list argumentsBjörn Gustavsson
2011-01-17Allow packing of some more instructionsBjörn Gustavsson
2011-01-17Support packing of the 'I' type in a 64-bit emulatorBjörn Gustavsson
In many (not all) cases, the value for the 'I' type will fit into 32 bits.
2011-01-17beam_makeops: Refactor packing code to facilitate extensionsBjörn Gustavsson
We don't want the packable types listed in two places.

2011-01-17BEAM loader: Introduce a new move2_xxxx instructionBjörn Gustavsson
2011-01-17BEAM loader: Pack more instructions using a new 'Q' typeBjörn Gustavsson
Introduce a new 'Q' type, similar to 'P' except that it can be packed.
2011-01-17If the wordsize is 64 bits, pack up to 4 operands into a wordBjörn Gustavsson
In the 32-bit BEAM emulator, it is only possible to pack 3 register operands into one word. Therefore, the move2 instruction (that has 4 operands) needs two words for its operands. Take advantage of the larger wordsize in the 64-bit emulator and pack up to 4 operands into a single word.
2011-01-17Pass the external word size to the beam_makeops scriptBjörn Gustavsson
Giving the beam_makeops script access to the external word size (=the size of instruction words) will allow it to pack more operands into a word for the 64 bits emulator.
2011-01-17BEAM loader: Combine is_type/1 and is_eq/1 instructionsBjörn Gustavsson
In the transformation engine in the loader, an is_eq/1 instruction is currently always preceded by an is_type/1 instruction. Therefore, save a word and slight amount of time by combining those instructions into an is_type_eq/2 instruction.
2011-01-17BEAM loader: Omit type tests for instructions that don't need themBjörn Gustavsson
2011-01-17beam_debug: Fix dissambly of some variable-operand instructionsBjörn Gustavsson
The i_jump_on_val_zero/3 and i_select_tuple_arity/3 instructions were not disassembled correctly.
2011-01-17beam_debug: Change one occurrence of "X[0]" to "x[0]" for consistencyBjörn Gustavsson
2011-01-17beam_makeops: Allow -pack and -nonext to be combinedBjörn Gustavsson
2011-01-17beam_makeops: Relax requirements for having specific instructionsBjörn Gustavsson
2011-01-17BEAM loader: Fix bug in handling of "rest" argumentsBjörn Gustavsson
It would only really work in simple case like: select_val S=q Fail=f Size=u Rest=* => ... where all operands for a single instruction where bound to variables, and not for more complicated cases such as: i_put_tuple Dst Arity Puts=* | put PutSrc => ...
2011-01-17Remove the last vestiges of the allocating fmove/2 instructionBjörn Gustavsson
There was a version of the BEAM loader and emulator that had two versions of the fmove/2 instruction, one version that allocated heap space internally and a newer version that assumed that a previous test_heap/2 instruction had already allocated the heap space. Though the allocating fmove/2 instruction is no longer supported, some vestiges of it still remains.
2011-01-17Makefile.in: Add dependency for files generated by util/beam_makeopsBjörn Gustavsson
2011-01-17Add utils/count for counting the static instruction frequencyBjörn Gustavsson
2011-01-17Add erts_debug:instructions/0 for listing all specific instructionsBjörn Gustavsson
erts_debug:instructions/0 is useful for finding which specific instructions that are not used at all.

2011-01-11check return value of epmd server listen() callSteve Vinoski
The listen() call can fail due to a variety of conditions, so check its return value and if it fails, print a suitable debug message if appropriate and then exit. The exit values used are the same for those already used for bind() failures: 0 if the error is EADDRINUSE, 1 otherwise.
