2017-10-09Pack operands for combined instructions into the instruction wordBjörn Gustavsson
The operands for the first part of a combined instruction (the entry point following the OpCase() label) can safely be packed into the instruction word. This commit will make each of the following instructions one word shorter: bs_context_to_binary_x i_band_xcjtd i_bs_get_binary_all_reuse_xft i_bs_get_integer_imm_xWtftx i_bs_get_integer_small_imm_xWftx i_bs_init_bits_fail_xjtx i_bs_init_bits_fail_yjtx i_bs_init_bits_fail_heap_sIjtx i_bs_init_bits_heap_WItx i_bs_init_fail_xjtx i_bs_init_fail_yjtx i_bs_init_fail_heap_sIjtx i_bs_init_heap_WItx i_bs_start_match2_xfttx i_bs_start_match2_yfttx i_element_xjsd i_element_yjsd i_fast_element_xjId i_fast_element_yjId i_increment_xWtd i_increment_yWtd i_jump_on_val_xfIW i_jump_on_val_yfIW i_jump_on_val_zero_xfI i_jump_on_val_zero_yfI i_minus_xxjtd i_plus_xxjtd i_plus_xyjtd i_put_tuple_xI i_put_tuple_yI i_rem_xxjtd i_select_tuple_arity_xfI i_select_tuple_arity_yfI i_select_tuple_arity2_xfAA i_select_tuple_arity2_yfAA i_select_val2_xfcc i_select_val2_yfcc i_select_val_bins_xfI i_select_val_bins_yfI i_select_val_lins_xfI i_select_val_lins_yfI

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?

2017-10-05Pack 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.

2017-10-02erts: Fix bug when detecting bad dist messageSverker Eriksson
We can't just leave it in queue with dist_ext=NULL. Two symptoms seen: 1. 'receive' trying to deref dist_ext as NULL. 2. GC think it's a term and put THE_NON_VALUE in root set.

2017-10-02Fix zlib merge snafuJohn Högberg
I accidentally merged a few fixes directly to maint-20 (and then to maint and master), instead of merging to maint and master and waiting for a patch to merge it into maint-20, leaving the related tickets dangling. This commit does nothing beyond getting the tickets (and their release notes) into the next patch.
