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.

2010-12-02Stop using uncertain flags for getaddrinfo()Raimo Niskanen
The AI_V4MAPPED flag is falling out of grace in modern IPv6 stacks, for security reasons, e.g. FreeBSD do not document it any longer. The AI_ADDRCONFIG flag have got unclear semantics on the same OS.

* rickard/rwmutex-bug/OTP-8925: Miscellaneous rwmutex bug fixes and improvements Don't use more reader groups than schedulers New test suite containing stress tests of the rwmutex implementation Conflicts: erts/emulator/beam/erl_init.c
2010-12-01Miscellaneous rwmutex bug fixes and improvementsRickard Green
The ERTS internal rwlock implementation could get into an inconsistent state. This bug was very seldom triggered, but could be during heavy contention. The bug was introduced in R14B (erts-5.8.1). The bug was most likely to be triggered when using the read_concurrency option on an ETS table that was frequently accessed from multiple processes doing lots of writes and reads. That is, in a situation where you typically don't want to use the read_concurrency option in the first place.
