This is needed for use on 32 bit with very large floats.
|
|
|
|
|
|
These tests are useful when the difference between the
bignum and float is larger than one bignum segment.
|
|
As it is possible to assume that bignums are bigger than smalls,
we can just check the sign of the bignum.
|
|
|

For floating point values which are greater than 9007199254740990.0 or
smaller than -9007199254740990.0, the floating point numbers are now
converted to integers during comparison with an integer. This makes
number comparisons transitive for large floating point numbers.

Each gc_bif[123] instruction must have both a transformation in
ops.tab and special code in gen_guard_bif[123]().
Rewrite it to do most of the work in gen_guard_bif[123]().
|
|
In the handling of generic instructions, we used to always
test whether the instruction was 'too_old_compiler' and abort
loading with a special error message.
Refactor the code so that we only do test if we an error
has occurred. That will allow us to make the test more expensive
in the future, allowing us to customize error messages for certain
opcode without any cost in the successful case.

'store_var' is always followed by 'next_arg'.
|
|
'next_instr' is always followed by 'is_op'.
|
|
Since the 'new_instr' instruction always occurs before the
'store_op' instruction, we can merge the instructions into one.
Also, there is no need to include the arity of the BEAM
instruction as an operand, since the arity can be looked up
based on the opcode.
|
|
A 'call' instruction in the loader transformation language is
always followed by an 'end' instruction, so we can replace the
'call' instruction with a 'call_end' instruction.
|
|
We don't need type constraints that essentially are assertions;
the wrong type will be detected and loading aborted when no specific
instruction can be found.
|
|
If the left part of a transformation will always match, omit the
the 'try_me_else' and 'fail' instructions.
As part of this optimization, make it an error to have a
transformation that can never be reached because of a previous
transformation that will always match. (Remove one transformation
from ops.tab that was found to be unreachable.)
|
|
|
|
This optimization will save some space (in the loader tables) and
some loading time.
|
|
Fix the incorrect code that attempted to remove a single
'next_arg' instructions before 'next_instr'.
|
|
I accidentally removed a little too much, only peercert/2 was deprecated.
|
|
It is more useful to have a helper function that can test for
any instruction.
|
|
is_list/2 and other test instructions with a zero label was last
generated by the v1 BEAM compiler which was last supported in R6B.
Since BEAM modules produced by that compiler will be rejected with
a nice error message for other reasons (e.g. by the test for the
module_info/0,1 functions), retaining those transformations serves
no useful purpose.
|
|
The hybrid-heap emulator is broken since R12, so there is no
need to keep those instructions.
|
|
Ancient versions of BEAM compiler could generate move instruction with
the same source and destination registers, so the loader would optimize
away such instructions.
|
|
|
|
Now, in child specification, the shutdown value can also be set to infinity
for worker children. This restriction was removed because this is not always
possible to predict the shutdown time for a worker. This is highly
application-dependent.

Previously error:badarg was raise if there was no underlying support
for SCTP. Handle both new and old failure until OTP-9239 is merged.

Simply return a tail of the flattened filename.

|
Since his function will be called only once, caching is a waste of
memory.
|
|
Pre-building the tuples returned by os:type/0 (system_info(os_type))
and os:version() (system_info(os_version)) saves some run-time and
avoids building garbage in the calling process.
|
|
In particular, move code out of init_per_suite since failure
causes end_per_suite to be skipped. Cleanup is simpler if both
init and cleanup happen as testcases.
