2011-10-26erts-hipe: Adapt generated BIF wrappers for new calling conventionSverker Eriksson
x86 and amd64: Push BIF__ARGS array on C-stack. ppc, sparc and arm: Write BIF__ARGS array to P->def_arg_reg[] Just the simplest solution with limited assembler knowledge, probably room for improvements.
2011-10-26erts-hipe: Remove obscuring macros in generated assembler codeSverker Eriksson
No semantic change. Just easier to debug when jumps are spelled out and not obscured by yet another layer of macros.
2011-10-26erts-hipe: Make hipe enabled emulator compile with new BIF callsSverker Eriksson
A first step to adapt hipe to the new BIF calling convention.
2011-10-26Simplify the instructions for calling BIFsBjörn Gustavsson
Taking advantage of the new calling convention for BIFs, we only need one instruction to handle BIFs with any number of arguments. This change eliminates the limit of three arguments for BIFs, but traps are still limited to three arguments.
2011-10-26Change the calling convention for BIFsBjörn Gustavsson
The current calling convention for BIFs makes it necessary to handle each arity specially, since each argument for the BIF also becomes an argument for the C function implementing the BIF, which makes it hard to allow BIFs with any number of arguments. Change the calling convention for BIFs, so that BIF arguments are passed in an array to the C function implementing the BIF.
2011-10-26Use the proper macros in all BIFsBjörn Gustavsson
As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction.

2011-10-13Allow noncharacter code points in unicode encoding and decodingBjörn Gustavsson
The two noncharacter code points 16#FFFE and 16#FFFF were not allowed to be encoded or decoded using the unicode module or bit syntax. That causes an inconsistency, since the noncharacters 16#FDD0 to 16#FDEF could be encoded/decoded. There is two ways to fix that inconsistency. We have chosen to allow 16#FFFE and 16#FFFF to be encoded and decoded, because the noncharacters could be useful internally within an application and it will make encoding and decoding slightly faster.

2011-10-13make_preload: Don't output a C comment start inside a commentBjörn Gustavsson
We already avoid outputting a comment terminator ("*/") inside a comment to avoid causing a syntax error. Also avoid outputting the start of a comment ("/*") to avoid causing a compiler warning. Noticed-by: Tuncer Ayaz

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.

2011-09-22Fix lost wakeup of scheduler when enqueuing auxiliary workRickard Green
When auxiliary work was enqueued on a scheduler, the wakeup of the scheduler in order to handle this work could be lost. Wakeups in order to handle ordinary work were not effected by this bug. The bug only effected runtime systems with SMP support as follows: * Deallocation of some ETS data structures could be delayed. * On Linux systems not using the NPTL thread library (typically ancient systems with kernel versions prior to 2.6) and Windows systems, the {Port, {exit_status, Status}} message from a terminating port program could be delayed. That is, it only effected port programs which had been started by passing exit_status as an option to open_port/2.
