Bifs that are called through the export entry
using i_call_last could have their cp set to
return_trace, just like any other call. So we
have to unwind the trace stack to get the correct
cp. Not doing this creates a lot of issues for
fprof.

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

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
|
|
Having the instruction name available in the functions
that implement packing also simplifies debugging.
|
|
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?

On 64-bit machines where the C code is always at address below 4Gb,
pack one or more operands into the instruction word.
|
|
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.
|
|
We want the flags to be available for other tests in configure.in.

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.

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.
