2011-02-03HALFWORD first stab at high mem allocSverker Eriksson
2011-02-03HALFWORD ETS relative termsSverker Eriksson
In halfword emulator, make ETS use a variant of the internal term format that uses relative offsets instead of absolute pointers. This will allow storage in high memory (>4G). Preprocessor macros (like list_val_rel(TERM,BASE)) are used to make normal (fullword) emulator almost completely unchanged while still reusing most of the code.

2011-01-24Track parents when expanding #xmlElement recordsUlf Wiger
The function xmerl_lib:expand_content/1 is mainly for expanding Simple XML, but can also handle xmerl records. This patch fixes an omission that caused expand_content/1 to not maintain the 'parents' list when expanding #xmlElement{} records. No test cases written, since the xmerl test suites have not yet been released.
2011-01-24Merge branch 'nick/orber/inet6_test_cases/OTP-9035' into maint-r14Erlang/OTP
* nick/orber/inet6_test_cases/OTP-9035: OTP-9035 - More tests added so that Orber does not try to run IPv6 tests on a machine than cannot handle that. This only affect test code and not the application.
2011-01-24Merge branch 'nick/ssh/sign-verify-binary' into maint-r14Erlang/OTP
* nick/ssh/sign-verify-binary: Updated appup file. Updated notes file. Changed year in copyright header. Added updated modules to the appup file. Improved error handling for ssh:connect/3/4. Release note contained wrong ticker number. OTP-8987 In some cases SSH returned {error, normal} when a channel was terminated unexpectedly. This has now been changed to {error, channel_closed}.

2011-01-17c: Reduce memory footprintBjörn Gustavsson
Use a binary instead of a string for the help text.
2011-01-17erl_posix_msg: Reduce memory footprintBjörn Gustavsson
Since the error messages in the erl_posix_msg module are presumably used very seldom, save memory by using binaries instead of strings.
2011-01-17Introduce a few more variations of the move instructionsBjörn Gustavsson
Frequency counts show that move Const x(1) move Const x(2) are very common.
2011-01-17Combine a move + jump sequence into the move_jump instructionBjörn Gustavsson
That will save one word and small amount of time for each occurrence.
2011-01-17Optimize and clean-up the exact equality/non-equality instructionsBjörn Gustavsson
The is_eq_exact/3 and is_ne_exact/3 instructions are commonly used with one immediate or literal operand. Introduce three new specialized instructions: i_is_eq_exact_literal/3 i_is_ne_exact_immed/3 i_is_ne_exact_literal/3 The i_is_ne_exact_literal/3 instruction is not very frequently used, but its existence is justified because we removed in a a previous commit the special instruction for matching bignums and we now use i_is_ne_exact_literal/3 instead. For consistency, rename the existing is_eq_immed/3 instruction to is_eq_exact_immed/3. While at it, remove the optimization of an is_eq/3 instruction with an immediate operand because that optimization is already done by the compiler.
2011-01-17Optimize addition of a small integer to a variableBjörn Gustavsson
Introduce a new i_increment/4 to optimize the addition of a register and a small integer. This instruction saves two instruction words compared to the standard instructions (an i_fetch/2 instruction followed by a i_plus/3 instruction) and will also be slightly faster.
2011-01-17Introduce a special instruction for select_val with two valuesBjörn Gustavsson
The new instruction will save one word (because no size operand is needed), and is slightly faster. Handle select_tuple_arity in the same way.
2011-01-17Introduce a few more specialized put_list instructionsBjörn Gustavsson
2011-01-17Eliminate the "put_list c n Dst" instructionsBjörn Gustavsson
Since the literal (constant) pool was introduced in R12, the BEAM compiler will never generate a "put_list Const [] Dst" instruction (it will instead generate a "move [Const] Dst" instruction).
2011-01-17Eliminate the specific move_sd instructionBjörn Gustavsson
The move_sd specific instruction is no longer used since there are specific move instructions covering all possible permutations of operands. Also eliminate the move_cy instruction because it is almost never generated by the compiler.
2011-01-17Eliminate use of GetArg1() in the badmatch and case_end instructionsBjörn Gustavsson
Create separate instructions for each register type. The "badmatch x(0)" and "case_end x(0)" (which are very common) will only require a single word each, compared to two words when GetArg1() is used.
2011-01-17Eliminate use of GetArg2() in the i_element instructionBjörn Gustavsson
Use separate instructions for each register type.
2011-01-17Eliminate use of GetArg1() in the fast_element instructionBjörn Gustavsson
Use separate instructions for each register type.
2011-01-17Eliminate use of GetArg1() in the jump_on_val* instructionsBjörn Gustavsson
