2017-09-11Avoid using $Src more than onceBjörn Gustavsson
The C compiler will probably optimize this, but just to be sure...

The 'S' operand type was added in 5bf73db9fd77.
2017-09-11Check the right side of a transformation betterBjörn Gustavsson
The right side of a transformation must be either a single call to a transformation function OR a list of instructions. Mixing them like this is not supported: some_instruction A B C => gen_something(A) | other B C Unfortunately, beam_makeops would silenty ignore anything after the function call, basically handling it in the same way as: some_instruction A B C => gen_something(A) Add a sanity check to reject such mixed right-hand sides.

2017-09-08Optimise equality comparisonsMichał Muskała
* In both loader and compiler, make sure constants are always the second operand - many passes of the compiler assume that's always the case. * In loader rewrite is_eq_exact with same arguments to skip the instruction and with different constants move one to an x register to maintain the properly outlined above. * The same (but in reverse) is done with the is_ne_exact, where we rewrite to an unconditional jump or add a move to an x register. * All of the above allow to replace is_eq_exact_fss with is_eq_exact_fyy and is_ne_exact_fss with is_ne_exact_fSS as those are the only possibilities left.
2017-09-07Replace ad-hoc MIN/MAX macros with common onesJohn Högberg
Besides being noisy, they were already defined by a global Unix- specific header, causing the Windows build to fail if one forgot to define them.

2017-09-05Replace the zlib driver with a NIFJohn Högberg
All operations will now yield appropriately, allowing them to be used freely in concurrent applications. This commit also deprecates the functions listed below, although they won't raise deprecation warnings until OTP 21: zlib:adler32 zlib:crc32 zlib:inflateChunk zlib:getBufSize zlib:setBufSize The behavior of throwing an error when a dictionary is required for decompression has also been deprecated.

2017-09-04Don't allow macros to assign to hard-coded variablesBjörn Gustavsson
It's bad style. Pass the name of the variable as an extra argument to the macro.
2017-09-04Annotate try_case_end as coldBjörn Gustavsson
try_case_end is an excepting-generating instruction that is infrequently executed.

2017-09-01Make cp_pos_to_col function aware of the ANSI escape codesGlauber Campinho
This fixes the issue with the function `move_cursor` described in #1536 and that causes the bug described in https://github.com/elixir-lang/elixir/issues/6504. The function `cp_pos_to_col` maps the current position in the buffer to the correct column on the screen, but it didn't handle ANSI escape codes. Since the ANSI escape codes aren't visible, the `cp_pos_to_col` now skips them when executing the calculations using `ansi_escape_width`. This new function only considers color escape codes, but also handles invalid codes.

2017-08-31erts: Suppress false memory leak for dlerrorSverker Eriksson
2017-08-31Optimize dispatch of loop_rec from recv_setBjörn Gustavsson
We KNOW that recv_set instruction is immediately followed by a loop_rec instruction.
2017-08-31Add missing -no_next directivesBjörn Gustavsson
2017-08-31Eliminate three arguments for erts_hibernate()Björn Gustavsson
We don't need to pass x(0), x(1), and x(2) because they can already be found in the register array.
2017-08-31Eliminate three arguments for the apply() helperBjörn Gustavsson
We don't need to pass x(0), x(1), and x(2) because they can already be found in the register array.
2017-08-31Assign machine registers for X86-64Björn Gustavsson
Keep frequently used variables in machine registers.
2017-08-31Annotate arithmetic instructions with likely/unlikelyBjörn Gustavsson
We expect that: * An arithmetic instruction is more likely to succeed than to fail. * An arithmetic instruction is more likely to have small operands than bignum operands.
2017-08-31Add annotations for likely/unlikelyBjörn Gustavsson
In a correct Erlang programs, we can expect that: * A GC test instruction (such as test_heap) is more likely not to do the GC. * A BIF is more likely to succeed than to fail. * A BIF is more likely to fail in a guard than in a body. * An apply or fun call is likely to succeed. Annotate conditions accordingly.
