2011-02-09Merge branch 'bjorn/compiler/eliminate-warnings' into devBjörn Gustavsson
* bjorn/compiler/eliminate-warnings: compiler Makefile: Turn warnings into errors v3_kernel_pp: Add support for pretty-printing #k_literal{} records v3_kernel_pp: Eliminate warning
2011-02-07v3_codegen: Use the latest instance of StBjörn Gustavsson
By accident a previous instance of St is used, which is harmless in this case, but leads to worse quality of the generated code.

We want to ensure that the compiler applications is kept free of warnings.

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}.
2011-01-24Merge branch 'nick/ensure_ssh_dir_exists/OTP-9010' into maint-r14Erlang/OTP

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
2011-01-17Eliminate use of GetArg1() in the select_val instructionBjörn Gustavsson
Instead of having one i_select_val_sfI instruction that uses the GetArg1() macro to fetch the controlling expression, use three separate instructions for each of the register types. That will save one word when selecting on the {x,0} register. It should also be slightly faster since a conditional branch is eliminated. Although it seems that the BEAM compiler will never generate a constant controlling expression (even with optimizations turned off), we still make sure that they will work by evaluating the select_val instruction at load time. Handle the select_tuple_arity instruction in the same way.
2011-01-17beam_emu: Eliminate sloppy use of tmp_arg1 and tmp_arg2Björn Gustavsson
The tmp_arg1 and tmp_arg2 variables are intended for transferring values from the fetch/2 instructions to instructions such as i_plus/3. In many places, however, tmp_arg1 and tmp_arg2 are used as general temporary variables within a single instruction. Improve the code generation by replacing sloppy use of tmp_arg1 and tmp_arg2 with block-local variables. In most cases, that will allow the temporary values to be kept in registers.
2011-01-17beam_emu: Don't inline helper functions into process_main()Björn Gustavsson
By default, GCC will inline calls to helper functions. Since process_main() is already huge, there is no reason to inline the helper functions (and some of them are used very seldom).
