- 10.5% reduction of o//depend dependency graph
- 8.8% reduction in latency of make command
- Fix issue with temporary file cleanup
There's a new -w option in compile.com that turns off the recent
Landlock output path workaround for "good commands" which do not
unlink() the output file like GNU tooling does.
Our new GNU Make unveil sandboxing appears to have zero overhead
in the grand scheme of things. Full builds are pretty fast since
the only thing that's actually slowed us down is probably libcxx
make -j16 MODE=rel
RL: took 85,732,063µs wall time
RL: ballooned to 323,612kb in size
RL: needed 828,560,521µs cpu (11% kernel)
RL: caused 39,080,670 page faults (99% memcpy)
RL: 350,073 context switches (72% consensual)
RL: performed 0 reads and 11,494,960 write i/o operations
pledge() and unveil() no longer consider ENOSYS to be an error.
These functions have also been added to Python's cosmo module.
This change also removes some WIN32 APIs and System Five magnums
which we're not using and it's doubtful anyone else would be too

DESCRIPTION
Lua is a language designed for embedded use in native applications. It
has an impossibly elegant C API and the Lua language itself feels more
like Python compared to alternatives like Tcl except it's a great deal
faster and doesn't have strong opinions about character encoding.
PROVENANCE
https://github.com/lua/lua/
commit e7803f7dbcdc966ab1f9db143424ee811ab1a398
Author: Roberto Ierusalimschy <roberto@inf.puc-rio.br>
Date: Wed Mar 3 09:44:20 2021 -0300
New release number (5.4.3)
luac.c needed to be sourced from:
https://www.lua.org/ftp/lua-5.4.3.tar.gz
LOCAL MODIFICATIONS
Lua now uses a bestline REPL with bash-style code completion.
Integer literals such as `033` will now be interpreted as octal.
Integer literals such as `0b10` will now be interpreted as binary.
The `\e` string literal escape sequence has been added, which is
equivalent to `\27` (the Lua version of `\033`) or the ASCII ESC
character. It may be used for teletypewriter control like having
bold text, which can be encoded elegantly as `\e[1mHELLO\e[0m`.
Added luaL_traceback2() for function parameters in traceback.
Added Python-like printf modulus operator for strings.
Added Python-like printf multiply operator for strings.
