2014-08-08erts: Fix neg int overflow when sint is min sizeLukas Larsson
When INT64_MIN is the value of a Sint64 we have to first cast it to an Uint64 before negating it. Otherwise we get an integer overflow which is undefined behaviour and in gcc 4.9 this results in -0 instead of -9223372036854775808 in gcc 4.8.
2014-05-22Make binary BIFs converting from lists yield on large inputRickard Green
- erlang:list_to_binary/1 - erlang:iolist_to_binary/1 - erlang:list_to_bitstring/1 - binary:list_to_bin/1
2013-09-20Check all pattern arguments passed to binary:matches/2Mike Sassak
Including an empty binary as one of multiple patterns passed to binary:matches/2 would crash BEAM with: "Cannot reallocate 1342177280 bytes of memory (of type "tmp")". This ensures each pattern is valid before trying to match.

2011-11-16Remove GCC 4.6 set-but-not-used warning from erl_bif_binaryPatrik Nyblom
2011-11-16Make binary:match with scope return correct valuesPatrik Nyblom
2011-10-26Use the proper macros in all BIFsBjörn Gustavsson
As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction.

2010-08-30Merge branch 'pan/ets_binary_overhead/OTP-8762' into devPatrik Nyblom
* pan/ets_binary_overhead/OTP-8762: Remove binary overhead counter from ets objects
2010-08-19Remove binary overhead counter from ets objectsPatrik Nyblom
As the overhead counter got larger and never really was needed in ets objects, I removed them. A few stray comments of XXX:PaN type from halfword dev removed in the process.
2010-08-12Increase vheap counter to Uint64Björn-Egil Dahlberg
This will reduce the risk of integer wrapping in bin vheap counting. The vheap size series will now use the golden ratio instead of doubling and fibonacci sequences. OTP #8730
2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.

2010-05-17Add documentation for binary modulePatrik Nyblom
Correct behaviour of copy/2 witn 0 copies.
2010-05-17Add more tests and make some go easier on small systemsPatrik Nyblom
Even more tests added to cover more error cases, some tests made easier on systems with small memories and timeouts made longer due to timetraps on solaris daily builds.
2010-05-17Correct Boyer More and trapping for longest_common_suffixPatrik Nyblom
Add testcases and clean up to get better code coverage.
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.
2010-05-17Add binary:{encode,decode}_unsigned({1,2}Patrik Nyblom
Add testcases for encode/decode_unsigned/1,2.
2010-05-17Add referenced_byte_size/1Patrik Nyblom
Add testcases for referenced_byte_size/1. Add failure tests for referenced_byte_size.
2010-05-17Add binary:list_to_bin/1 and binary:copy/1,2Patrik Nyblom
Add testcases for binary:list_to_bin/1 and binary:copy/1,2. Add reference implementation of list_to_bin/1.
2010-05-17Add bin_to_list/{1,2,3}Patrik Nyblom
Add testcases for bin_to_list. Teach binref.erl bin_to_list.
2010-05-17Add binary:longest_common_prefix/longest_common_suffixPatrik Nyblom
Add allcoator parameter to erts_get_aligned_binary_bytes_extra. Add testcases for the functions above. Add reference implementation for the functions above.
2010-05-17Add binary:part to erl_bif_binary.cPatrik Nyblom
Change name of the 'scope' option for binary:match/matches. Add split and replace to binary.erl. Cleanup comments etc in binary.erl and atom.names Add testcases for part, split, replace and scopes.
2010-05-17Move binary module bif's to erl_bif_binary.cPatrik Nyblom
