* 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.

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.

It's bad style. Pass the name of the variable as an extra argument to the macro.
