Correct erlang:is_builtin/3 for apply/2 and yield/0
|
|
* maint:
erl_process_dump: Don't assume that literals can be found
Remove one superfluous closing parenthesis in oam_intro.xml
|
|
Native code does not register its literals in the code header for the
loaded code. Therefore, a literal created by native code can not be
found by mark_literal(). Ignore literals that can't be found instead
of crashing (the crasdump_viewer will report such literals as
incomplete heap data, but will not crash).

erlang:is_builtin(erlang, M, F) returns false for apply/2 and
yield/0. The documentation for erlang:is_builtin/3 says that it
returns true for BIFs that are implemented in C. apply/2 and
yield/0 are implemented in C (as BEAM instructions), and
therefore the correct return value is true.
Also see a similar argument that was made for apply/3 in the past:

When the cpu ids and scheduler ids don't match,
the end schedulers could end up not being bound
when they should be.
example:
> taskset -c 1-3 erl +S 4 +sbts
> erlang:system_info(scheduler_bindings).
{1,2,3,unbound}
This fix makes it so that all cores are used to
bind schedulers.

* bjorn/compiler/match-literals:
Optimize instructions for comparing a register with a literal
Optimize matching of literals for single-valued types
|
|
We can avoid calling eq() from the is_eq_exact_literal/3
and is_ne_exact_literal/3 instructions if the source operand is
an immediate (since a literal is either a boxed or a list, never
an immediate).

Bump version of crash dumps to 0.4

Don't dump literal areas that are not referenced at all

|
|
|
When a literal was used from several processes, the literal would
be dumped in only one of the processes. The other processes
that referenced the literals would have incomplete heap data.
|
|
Maps would be dumped as the atom 'undefined', which is
not very informative.
|
|
Writing of crash dumps were done using unbuffered IO. This
is slow since many small writes are done.
Use a FILE* with an allocated buffer to obtain buffered IO.
I wrote a small test program that created 50000 binaries of 200 bytes
each and then created a crash dump. The crash dumping was an order of
magnitude faster with buffered IO than without.

erts: Use SIGRTMIN on linux for sys_suspend

The Linux real-time signal is better used on Linux
for suspending schedulers during shutdown as it doesn't
collide with SIGUSR2 usage of other applications.

Various places that now reject null chars inside strings
- Primitive file operations reject it in filenames.
- Primitive environment variable operations reject it in
names and values.
- os:cmd() reject it in its input.
Also '=' characters are rejected by primitive environment
variable operations in environment variable names.
Documentation has been updated to document null characters
in these types of data as invalid. Currently these operations
accept null chars at the end of strings, but that will change
in the future.

The try_end and try_case instructions are implemented the same way
(try_case is translated to try_end by the loader).
We can do better than that. We know that try_case will only be executed
when an exception has been caught. Therefore, we know that x(0) is
the non-value and that x(1) through x(3) need to be shifted down to
x(0) through x(2). There is no need to test x(0) before shifting down.
try_end does not need the register shifting code at all.

* sverker/bad-dist-msg-bug/ERIERL-80/OTP-14661:
erts: Fix bug when detecting bad dist message
Add distribution_SUITE:bad_dist_ext_size
|
|
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.

* bjorn/erts/pack-with-opcode/OTP-14325:
Pack operands for combined instructions into the instruction word
beam_makeops: Use named arguments for the code generation functions
Optimize packing for "optional use" operands
beam_makeops: Print the instruction name for fatal packing errors
Introduce a syntax for marking operands as "optional use"
beam_makeops: Refactor parsing of specific instructions

Move LD flags for hipe from Makefile.in to configure.in
beam_disasm: Correct printing of y registers
ops.tab: Slightly optimize badmatch on a Y register
macros.tab: Fix assertion in SET_I_REL()
|
|
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 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.
