sverker/on_load-on_load-bug/OTP-14612
|
|
Symptom: VM crash when erlang:trace_pattern(on_load, ..) is set and
module with -on_load is loaded.
Problem: Tracing and -on_load clash in their use of Export.beam[1]
Solution: Do not do call set_default_trace_pattern in finish_loading_1
for modules with -on_load. finish_after_on_load_2 will do that anyway.

calling write_buf
After deleting the chars the function `del_chars` was considering the code points to move the cursor back and not the graphemes

Introduce new macros that can be used for relative jumps and
use them consistently.
Test that everything works by using a non-zero constant JUMP_OFFSET.
The loader subtracts JUMP_OFFSET from loaded labels, and all
instructions that use 'f' operands add it back.

* bjorn/erts/improve-beam-ops:
Add built-in macros $ARG_POSITION() and $IS_PACKED()
Use 't' instead of 'I' bit syntax operands
Optimize operand type for match context in i_bs_get_integer

Use the correct name of the parameter

The number of live registers, unit and flags, and the number
of slots all fit comortably in 16 bits. This change will give
more opportunities for packing.
|
|
The match context is always in an X register. Change the 's' operand
to 'x'.
While we are it, also change the operands for Live and FlagsAndUnit
to 't' (they will both fit comfortably in 16 bits).
|
|
'S' is slightly more efficient. Using 'S' may also enable more
packing.
|
|
|
|
As a preparation for introducing relative jumps, introduce
"trace_jump W" that can be used for tracing. This instruction
will continue to have an absolute address for the jump target.
(Note: This instruction is never created during loading; it
is only created in stubs when tracing is active.)

The C compiler will probably optimize this, but just to be sure...

* lukas/erts/pgo/OTP-14604:
Add support for building a pgo beam_emu
|
|
The 'S' operand type was added in 5bf73db9fd77.
|
|
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.

* 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.

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.

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.
