2010-11-22ETS 'compressed' option.Sverker Eriksson
The compressed format is using a slighty modified variant of the extern format (term_to_binary). To not worsen key lookup's too much, the top tuple itself and the key element are not compressed. Table objects with only immediate non-key elements will therefor not gain anything (but actually consume one extra word for "alloc_size").
2010-11-18Move cpu topology functionality into erl_cpu_topology.[ch]Rickard Green
2010-08-17erts: Remove broken elib_mallocBjörn Gustavsson
elib_malloc is an alternate memory allocator that is no longer possible to build.
2010-08-17erts: Remove stray pre-ISO-C compatibility macrosBjörn Gustavsson
A long time ago, the Erlang run-time system could be build with pre-ANSI/ISO-C (K&R) C compilers, but that is no longer possible. Remove the remaining uses of the compatibility macros that made it possible that possible.
2010-08-07Align trailing message data for all types of structuresRickard Green
Alignment of trailing data in messages has been adjusted. This in order to be able to pass data of any type as trailing data in the future.
2010-06-01Remove stray SAE supportBjörn Gustavsson
The experimental Standalone Erlang (SAE) support based on Joe Armstrong's work has long been broken. Remove the remaining code and Makefile rules.
2010-05-20sys.h: Correct the get_int64() macroBjörn Gustavsson
The get_int64() macro has never been used (it was probably added for completeness at the same time that put_int64() was added), but it was not actually used and therefore it does not actually work.
2010-04-30emulator: Remove stray OSE/Delta supportBjörn Gustavsson
2010-04-30emulator: Eliminate #ifdef for sys_tty_reset()Björn Gustavsson
In the erts/emulator/beam sources #ifdef SOME_OPERATING_SYSTEM should be avoided. Instead, call a function implemented in sys/OPERATING_SYSTEM/sys.c.
2010-03-22Merge branch 'pan/otp_8332_halfword' into devErlang/OTP
* pan/otp_8332_halfword: Teach testcase in driver_suite the new prototype for driver_async wx: Correct usage of driver callbacks from wx thread Adopt the new (R13B04) Nif functionality to the halfword codebase Support monitoring and demonitoring from driver threads Fix further test-suite problems Correct the VM to work for more test suites Teach {wordsize,internal|external} to system_info/1 Make tracing and distribution work Turn on instruction packing in the loader and virtual machine Add the BeamInstr data type for loaded BEAM code Fix the BEAM dissambler for the half-word emulator Store pointers to heap data in 32-bit words Add a custom mmap wrapper to force heaps into the lower address range Fit all heap data into the 32-bit address range
2010-03-10Teach {wordsize,internal|external} to system_info/1Patrik Nyblom
Some test suites need to differentiate between 32-bit terms and 32-bit pointers. While at it, remove some more warnings in process.c for SMP and debug.
2010-03-10Add the BeamInstr data type for loaded BEAM codePatrik Nyblom
For cleanliness, use BeamInstr instead of the UWord data type to any machine-sized words that are used for BEAM instructions. Only use UWord for untyped words in general.
2010-03-10Store pointers to heap data in 32-bit wordsPatrik Nyblom
Store Erlang terms in 32-bit entities on the heap, expanding the pointers to 64-bit when needed. This works because all terms are stored on addresses in the 32-bit address range (the 32 most significant bits of pointers to term data are always 0). Introduce a new datatype called UWord (along with its companion SWord), which is an integer having the exact same size as the machine word (a void *), but might be larger than Eterm/Uint. Store code as machine words, as the instructions are pointers to executable code which might reside outside the 32-bit address range. Continuation pointers are stored on the 32-bit stack and hence must point to addresses in the low range, which means that loaded beam code much be placed in the low 32-bit address range (but, as said earlier, the instructions themselves are full words). No Erlang term data can be stored on C stacks (enforced by an earlier commit). This version gives a prompt, but test cases still fail (and dump core). The loader (and emulator loop) has instruction packing disabled. The main issues has been in rewriting loader and actual virtual machine. Subsystems (like distribution) does not work yet.
2009-12-11OTP-8323 Miscellaneous cross compilation improvements. For example, oneRickard Green
new mandatory configuration variable that replaces all other previously mandatory configuration variables, and better documentation. Note that old cross compilation configurations cannot be used without modifications. For more information see the $ERL_TOP/xcomp/README file.
