2017-10-09beam_makeops: Use named arguments for the code generation functionsBjörn Gustavsson
The number of arguments has become unwieldy.
2017-10-05Optimize packing for "optional use" operandsBjörn Gustavsson
Operands that are marked with a "?" are not always used when an instruction is executed. Enhance the packing algorithm to place optional use operands into the instruction word even they are not the first operand (as long as the total instruction size stays the same). Here are the instructions that will be packed differently because of this change: allocate_heap t I t? allocate_heap_zero t I t? test_heap I t? i_bs_get_integer_8 x f? x i_bs_get_integer_16 x f? x i_bs_get_integer_32 x f? x
2017-10-05beam_makeops: Print the instruction name for fatal packing errorsBjörn Gustavsson
Having the instruction name available in the functions that implement packing also simplifies debugging.
2017-10-05Introduce a syntax for marking operands as "optional use"Björn Gustavsson
Introduce a syntax to mark an operand that is not always used when an instrution is executed. Example of such operands are the fail label for is_nil or the number of live registers for an allocate instruction. Use a question mark to annotate optional use: is_nil f? xy allocate t t?

2017-10-05Optimize instruction prefetchBjörn Gustavsson
2017-10-05Pack operands into the instruction wordBjörn Gustavsson
On 64-bit machines where the C code is always at address below 4Gb, pack one or more operands into the instruction word.
2017-10-05Use 32-bits pointers to C codeBjörn Gustavsson
On a 64-bit machine, we only need 32 bits to store a pointer to the C code that implements a BEAM instruction. Refactor the code to only use the lower 32 bits of each instruction word, and take care to preserve the high 32 bits.
2017-10-05Move LD flags for hipe from Makefile.in to configure.inBjörn Gustavsson
We want the flags to be available for other tests in configure.in.

2017-10-02kernel: Rewrite gen_udp_SUITE:read_packet tcLukas Larsson
The old testcase did not test anything at all, it seems like it was written with the non-smp emulator inmind.
2017-10-02erts: disable kernel-poll on OS X vsn < 16Lukas Larsson
kqueue is broken on earlier versions of OS X.

2017-10-02erts: temp_alloc can no longer be disabledLukas Larsson
temp_alloc is used in such a way that if it ever results in a malloc/free sequence it will slow down the system alot. So it will no longer be possible to disable it and it will not be disabled when using +Mea min. OTP-14651

Move out from the head the variables that are only used in the excute phase.
2017-10-01Change operand from 'P' to 'Q' for i_apply_last and i_apply_fun_lastBjörn Gustavsson
All other instructions that increment the stack pointer takes a 'Q' operand.

Add the CHECK_ALIGNED() macro that can be used for testing that the storage destination is word-aligned.

2017-10-01beam_load.c: Generalize the 'P' operator in the packing engineBjörn Gustavsson
In the 'P' operator, don't assume that a packed target label ('f' or 'j') is always the leftmost argument. Instead, transfer the patch position from the accumulator to the stack.
