2017-09-11Merge branch 'lukas/erts/pgo/OTP-14604'Lukas Larsson
* lukas/erts/pgo/OTP-14604: Add support for building a pgo beam_emu
2017-09-11beam_debug: Add support for printing 'S' operandsBjörn Gustavsson
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.

* bjorn/erts/improve-beam-ops: Don't allow macros to assign to hard-coded variables Annotate try_case_end as cold beam_emu.c: Mark initialization code as unlikely Try to avoid generating unecessary do/while wrappers Eliminate unecessary instruction macro i_move_call_only()

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.

OTP-14527
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.

2017-09-04Try to avoid generating unecessary do/while wrappersBjörn Gustavsson
Make the generated code easier to read.

* bjorn/erts/improve-beam-ops: Optimize dispatch of loop_rec from recv_set Add missing -no_next directives Eliminate three arguments for erts_hibernate() Eliminate three arguments for the apply() helper Assign machine registers for X86-64 Annotate arithmetic instructions with likely/unlikely Add annotations for likely/unlikely ops.tab: Mark infrequently used instructions as %cold Introduce '%warm' and beam_warm.h
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.
2017-08-31ops.tab: Mark infrequently used instructions as %coldBjörn Gustavsson
Instructions that used to be implemented in beam_emu.c were not marked as cold as it would make no difference.
2017-08-31Introduce '%warm' and beam_warm.hBjörn Gustavsson
The bit syntax instructions are mixed among other instructions in beam_hot.h and beam_cold.h. Introduce a new hotness level called '%warm' with is associated file beam_warm.h. Mark all bit syntax instructions as '%warm'.

2017-08-29erts: Fix port_SUITE:dropped_commands tcLukas Larsson
We start the port in the started process in order to get the messages in the correct place and also so that unloading the port driver does not kill the test process.
2017-08-29De-duplicate bignums in the literal poolBjörn Gustavsson
Duplicate literals in the literal pool is a waste of memory. Also, having unique literals can simplify some loader optimizations, because we can known that if two literal indices are distinct, the values must be distcint too.
