Justine Tunney f4f4caab0e Add x86_64-linux-gnu emulator
I wanted a tiny scriptable meltdown proof way to run userspace programs
and visualize how program execution impacts memory. It helps to explain
how things like Actually Portable Executable works. It can show you how
the GCC generated code is going about manipulating matrices and more. I
didn't feel fully comfortable with Qemu and Bochs because I'm not smart
enough to understand them. I wanted something like gVisor but with much
stronger levels of assurances. I wanted a single binary that'll run, on
all major operating systems with an embedded GPL barrier ZIP filesystem
that is tiny enough to transpile to JavaScript and run in browsers too.

#
# SYNOPSIS
#
# Freestanding Hermetically-Sealed Monolithic Repository
#
# REQUIREMENTS
#
# You can run your programs on any operating system, but you have
# to build them on Linux 2.6+ (or WSL) using GNU Make. A modern C
# compiler that's statically-linked comes included as a courtesy.
#
# EXAMPLES
#
# # build and run everything
# make -j8 -O
# make -j8 -O MODE=dbg
# make -j8 -O MODE=opt
# make -j8 -O MODE=rel
# make -j8 -O MODE=tiny
#
# # build individual target
# make -j8 -O o//examples/hello.com
# o//examples/hello.com
#
# # view source
# less examples/hello.c
#
# # view binary
# o//tool/viz/bing.com o//examples/hello.com |
# o//tool/viz/fold.com
#
# # view transitive closure of legalese
# o//tool/viz/bing.com -n o//examples/hello.com |
# o//tool/viz/fold.com
#
# # basic debugging
# make -j8 -O MODE=dbg o/dbg/examples/crashreport.com
# o/dbg/examples/crashreport.com
# less examples/crashreport.c
#
# # extremely tiny binaries (scout's honor escape hatch)
# # please pay the $1k for commercial license if you can

# UNSPECIFIED PREREQUISITES TUTORIAL
#
# A build rule must exist for all files that make needs to consider in
# order to build the requested goal. That includes input source files,
# even if the rule is empty and does nothing. Otherwise, the .DEFAULT
# rule gets triggered.
#
# This is a normal and neecssary behavior when source files get deleted.
# The build reacts automatically to this happening, by simply deleting
# and regenerating the dependency graph; so we can safely use wildcard.
#
# This is abnormal if it needs to keep doing that repeatedly. That can
# only mean the build config is broken.
#
# Also note that a suboptimal in-between state may exist, where running
# `make -pn` reveals rules being generated with the .DEFAULT target, but
# never get executed since they're not members of the transitive closure
# of `make all`. In that case the build config could be improved.
