2011-10-26erts-hipe: Enable debug compiled hipe-VM with lock checkerSverker Eriksson
Add hipe_debug_bif_wrapper() as a wrapper for every BIF called by native code.
2011-10-26erts-hipe: Rename fail_bif_interface_0 to standard_bif_interface_0Sverker Eriksson
2011-10-26erts-hipe: Deliberate leak of native fun entriesSverker Eriksson
This is a workaround as hipe code upgrade/unloading does not work properly.
2011-10-26erts-hipe: Fix new trap conventions for x86, amd64 and ppcSverker Eriksson
2011-10-26Store the trap address in p->iBjörn Gustavsson
For cleanliness, store the trap address in p->i instead of in p->def_arg_reg[3].
2011-10-26Store the trap arguments in the X register arrayBjörn Gustavsson
Store arguments for a trap in the X register array to allow traps to have any number of arguments.
2011-10-26erts-hipe: Make some primops use new BIF calling conventionSverker Eriksson
These primops use the standard_bif_interface_X macros in hipe_bif_list.m4 and must therefor be implemented as bifs for things to work. Maybe there is room for optimization here to call the primops more directly with arguments in registers without having to push them on stack to emulate bif calls.
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

2011-10-11Do small optimisation on platforms with 32 bit EtermLukas Larsson
On 32 bit we know that a comparison with a lossfull double and a short will always give the float is being superior. So therefore we only have to check the sign on the double.
2011-10-11Add tests for equality checkingLukas Larsson
Test for checking equality on all float exponents Test in equality for all comparison tests
2011-10-11Optimize comparison of huge floats and smaller bignumsLukas Larsson
2011-10-11Add tests for comparing large floats and small bignumsLukas Larsson
2011-10-11Cleanup double_to_bignum conversion codeLukas Larsson
2011-10-11Update size of tmp cmp bignum bufferLukas Larsson
This is needed for use on 32 bit with very large floats.
2011-10-11Expand tests for float and number comparisonLukas Larsson
2011-10-11Update heauristic to work on halfwordLukas Larsson
2011-10-11Add heauristics bignum vs float checksLukas Larsson
These tests are useful when the difference between the bignum and float is larger than one bignum segment.
2011-10-11Optimise bugnum and small comparisonLukas Larsson
As it is possible to assume that bignums are bigger than smalls, we can just check the sign of the bignum.
2011-10-11Add float vs integer comparison testsLukas Larsson
2011-10-11Update integer and floating point number comparisonsLukas Larsson
For floating point values which are greater than 9007199254740990.0 or smaller than -9007199254740990.0, the floating point numbers are now converted to integers during comparison with an integer. This makes number comparisons transitive for large floating point numbers.

* bjorn/some-configure-clean-ups: erts/configure.in: Remove test for reversed setvbuf() arguments erts/configure.in: Remove broken support for System V erts/configure.in: Don't check for the presence of mach-o/dyld.h erts/configure.in: Remove useless --disable-fixalloc option
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.
