2012-06-25hipe_arm.c: remove dead codeMikael Pettersson
erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c, with #ifdefs to select ARM-specific code. Somehow those #ifdefs never got cleaned out, resulting in fairly ugly-looking code. This eliminates the #ifdefs, deletes dead PowerPC-specific code, and keeps only the ARM-specific code. I've verified that the exact same assembly code is generated for hipe_arm.c before and after this patch (if you compile without -g, with -g there are unavoidable changes to the debug data).

2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
2011-11-09erts,hipe: Limited support for hipe cross compilationSverker Eriksson
Normally hipe assumes that generated native code will be executed on the same emulator as the hipe compiler is running on. This commit allows you to build a hipe "cross-compiler" for a different configured emulator (but for same architecture). Example: > cd lib/hipe > make clean > make XCOMP=yes FLAVOR=smp TYPE=debug This hipe compiler will generate code to be executed on the debug compiled smp-emulator at $ERL_TOP.
2011-10-26erts-hipe: Change THE_NON_VALUE for HiPE enabled debug emulatorSverker Eriksson
This is a work-around as there are hipe BIFs that return untagged integers that may be intepreted as THE_NON_VALUE (24). Hipe bifs that return offsets as untagged integers: hipe_bs_put_utf8 hipe_bs_put_utf16be hipe_bs_put_utf16le Hipe bifs that return raw pointers: hipe_find_na_or_make_stub hipe_nonclosure_address
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: Fix new trap conventions for x86, amd64 and ppcSverker Eriksson
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.

2011-09-06BEAM: Unify allocation of X and float registersBjörn Gustavsson
In the half-word emulator, smp emulator, and non-smp emulator the X register and float register arrays were allocated in different ways. Always allocate the registers and store the pointers to the allocated register arrays in the scheduler data.
2011-08-16emulator: Add a fourth element in exception stacktracesBjörn Gustavsson
This commit is a preparation for introducing location information (filename/line number) in stacktraces in exceptions. Currently a stack trace looks like: [{Mod1,Function1,Arity1}, . . . {ModN,FunctionN,ArityN}] Add a forth element to each tuple that can be used indication the filename and line number of the source file: [{Mod1,Function1,Arity1,Location1}, . . . {ModN,FunctionN,ArityN,LocationN}] In this commit, the fourth element will just be an empty list, and we will change all code that look at or manipulate stacktraces.

All uses of the old deprecated atomic API in the runtime system have been replaced with the use of the new atomic API. In a lot of places this change imply a relaxation of memory barriers used.
2011-05-21Fix bug related to hibernate and HiPE (clear F_HIBERNATE_SCHED flag)Paul Guyot
F_HIBERNATE_SCHED flag that was introduced in b7ecdcd1ae9e11b8f75e must be cleared in hipe_mode_switch as well. Otherwise, processes running HiPE code that hibernate, wake up and then trap into a BIF will not be rescheduled.
