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.
2011-01-17Eliminate redundant jump instructionsBjörn Gustavsson
2011-01-17Eliminate the special instructions for selecting floats and bignumsBjörn Gustavsson
2011-01-17Add test for non-matching big numberBjörn Gustavsson
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.

2011-01-11Remove special treatment of EADDRINUSEPatrik Nyblom
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.
