2013-01-31compiler: Use the literal pool for floating point constantsBjörn Gustavsson
The BEAM loader will put floating point constants into the literal pools for the module, but it will not check for duplicates. We can do much better by having the compiler use the literal pool for floating point constants.
2012-02-20Fix discrepancy in compile_infoKostis Sagonas
The BEAM disassembler used the atom 'none' to signify the absence of a compile_info chunk in a .beam file. This clashes with the type declaration of the compile_info field of a #beam_file{} record as containing a list. Use [] to signify the absence of this chunk. This simplifies the code and avoids a dialyzer warning. For fixing a similar problem and for consistency, changed also the return type of the attributes field of the #beam_file{} record. This required a change in the beam_disasm test suite.

2011-09-21beam_disasm: Handle stripped BEAM filesHaitao Li
beam_disasm:file/1 would crash if asked to disassemble a stripped BEAM file without an "Attr" chunk.
2011-08-16Include location information for line instructions in BEAM filesBjörn Gustavsson
2011-08-16compiler, emulator: Introduce the line/1 instructionBjörn Gustavsson
Introduce the line/1 instruction in the compiler and the BEAM virtual machine. It will not yet be generated by the compiler and will not actually carry any information.
2010-05-20Remove stray support for the put_literal/2 instructionBjörn Gustavsson
put_literal/2 was an experimental instruction added in R11 to support literals, but before the R12 release support for literals was implemented for all instruction, making the put_literal/2 instruction redundant. Although the beam_disasm module supports dissambley of instructions in older releases, there is no reason to have it support experimental instructions.
2010-05-20Remove stray support for the bs_bits_to_bytes2/2 instructionBjörn Gustavsson
bs_bits_to_bytes2/2 was an experimental instruction added in R11, but was removed in R12. Although the beam_disasm and beam_validator modules do support instructions in older releases, there is no reason to have them support experimental instructions.
2010-05-17Add guard BIFs binary_part/2,3Patrik Nyblom
Add the gc_bif's to the VM. Add infrastructure for gc_bif's (guard bifs that can gc) with two and. three arguments in VM (loader and VM). Add compiler support for gc_bif with three arguments. Add compiler (and interpreter) support for new guard BIFs. Add testcases for new guard BIFs in compiler and emulator.

* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)
2010-05-11Introduce the new recv_mark/1 and recv_mark/1 instructionsBjörn Gustavsson
Make the recv_mark/1 and recv_mark/1 instructions known to the compiler and run-time system. For the moment, make the loader ignore any occurrences of those instructions in BEAM files. Also update hipe_beam_to_icode to ignore those instructions.
