bjorng/bjorn/compiler/fix-atom-leak/ERL-563/OTP-14968
Stop the compiler from overflowing the atom table
|
|
The expressions fun M:F/A, when all elements are literals are also
treated as a literal. Since they have consistent representation and
don't depend on the code currently loaded in the VM, this is safe.
This can provide significant performance improvements in code using such
functions extensively - a full function call to erlang:make_fun/3 is
replaced by a single move instruction and no register shuffling or
saving registers to stack is necessary. Additionally, compound data
types that contain such external functions as elements can be treated as
literals too.
The commit also changes the representation of external funs to be a
valid Erlang syntax and adds support for literal external funs to core
Erlang.

Sharing these settings for all schedulers can degrade performance,
so it makes sense to be able to configure them separately.
This also changes the default busy-wait time to "short" for both
kinds of dirty schedulers.

I have read the man pages for most socket and file operations
on recent Linux, FreeBSD, OpenBSD and Solaris 10 and noted
the possible error codes.
Which error codes that are possible for file operations have
been updated in file:posix/0. Error codes for socket operations
in inet:posix/0. The latter refers to the former so it is
a superset, assuming that e.g sendfile and AF_UNIX socket
operations could cause socket operations to return any file
error code. That is not entirely true, but could be,
especially in the future.
Added to file:posix/0 are:
ebadmsg edeadlk edeadlock eftype emultihop enobufs enolck enolink
enosr enostr enosys eopnotsupp eoverflow erange etxtbsy
Added to inet:posix/0 are all but:
exbadport exbadseq file:posix()
These are still possible according to erl_posix_str.c,
but are not in file:posix/0 nor in inet:posix/0,
and many of them are not file nor inet related, but some might be:
e2big eadv ealign ebade ebadfd ebadr ebadrpc ebadrqc

[ERL-557] add is_empty/1 to sets and ordsets
OTP-14996, ERL-557, PR-1703

Use integer variable names instead of atoms in v3_core, sys_core_fold,
and v3_kernel to avoid overflowing the atom table.
It is a deliberate design decision to calculate the first free integer
variable name (in sys_core_fold and v3_kernel) instead of somehow
passing it from one pass to another. I don't want that kind of
dependency between compiler passes. Also note that the next free
variable name is not easily available after running the inliner.

The way variables created by make_template() are used, it is necessary
that the names are unique in the entire function. This has not
happened to cause any problems in the past because all other compiler
passes created atom variable names, not integer variable names. If
other passes start to create integer variable names, this bug is
exposed.
|
|
During compilation, the bs_save2 and bs_restore2 instructions contain a match
context reference. That reference is the variable name that holds the match context.
beam_clean assumes that the reference always is an atom, which is not a safe assumption
since integers are legal variable names in Core Erlang.
