2011-11-02beam_loader: Support external funs in the literal poolBjörn Gustavsson
A future release of the compiler might want to treat external funs as literals. Make sure that the loader can cope with an export entry being created from both an entry in the literal pool and from the export table (i.e. if an external fun refers to an exported function in the same module).
2011-11-02beam_load.c: Clarify error message when loading unsupported BEAM filesBjörn Gustavsson
Make it clear for the user what has happened and how to fix it when an attempt is made to load a BEAM file containing new instructions that the current run-time system cannot handle. Suggested-by: Thomas Lindgren

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.
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.
