2010-06-03Fix ops.tab to include i_return_time_traceBjörn-Egil Dahlberg
Without the instruction defined in ops the interpreter will not compile when using NO_JUMPTABLE.
2010-06-03Call time breakpoint tracing frameworkBjörn-Egil Dahlberg
Initial commit with a new breakpoint instruction and PSD areas for temporary time storage during tracing.
2010-05-20Remove the bs_bits_to_bytes/3 instructionBjörn Gustavsson
The last compiler to generate code that uses the bs_bits_to_bytes/3 instruction was the R11 compiler. Since we don't support loading R11 *.beam files in R14, removing the remaining support for the instruction.
2010-05-20erts: Stop supporting non-literal empty tuplesBjörn Gustavsson
Since R12B, empty tuples are literals. Thus the compiler will no longer generate the instruction: put_tuple 0 Destination for creating an empty tuple. It is now time to stop supporting that instruction in the run-time system. While we are at it, correct a typo.
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.
2010-05-11erts: Implement recv_mark/1 and recv_set/1 for realBjörn Gustavsson
The recv_mark/1 instruction will both save the current position in the message queue and a mark (the address of the loop_rec/2 instruction just following the recv_set/1 instruction). The recv_mark/1 instruction will only use the saved position if the mark is correct. The reason for saving and verifying the mark is that the compiler does not need to guarantee that no other receive instruction can be executed in between the recv_mark/1 and recv_set/1 instructions (the mark will be cleared by the remove_message/0 instruction when a message is removed from the message queue). That means that arbitrary function calls in between those instruction can be allowed.
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.
2010-04-07erts: Fix loading of modules with invalid floating point arithmeticBjörn Gustavsson
The following program is supposed to cause an exception at run-time: foo() -> Sum1 = Sum2 = N = 2, pSum - (Sum1*(Sum2/N)). but the loader fails to load because it contains the following instruction: fconv {atom,pSum} {fr,2} Fix the loader so that it can handle fconv instructions where the first operand is a non-numeric literal.

2010-03-22erts: Don't support the put_string/3 instructionBjörn Gustavsson
Since R14 does not need to load code that can also be loaded in an R11 run-time system, support for the put_string/3 instruction can be removed.
