# - Debuggable
Introduce --strace flag for system call tracing This is similar to the --ftrace (c function call trace) flag, except it's less noisy since it only logs system calls to stderr. Having this flag is valuable because (1) system call tracing tells us a lot about the behavior of complex programs and (2) it's usually very hard to get system call tracing on various operating systems, e.g. strace, ktrace, dtruss, truss, nttrace, etc. Especially on Apple platforms where even with the special boot trick, debuggers still aren't guaranteed to work. make -j8 o//examples o//examples/hello.com --strace This is enabled by default in MODE=, MODE=opt, and MODE=dbg. In MODE=dbg extra information will be printed. make -j8 MODE=dbg o/dbg/examples o/dbg/examples/hello.com --strace |& less This change also changes: - Rename IsText() → _istext() - Rename IsUtf8() → _isutf8() - Fix madvise() on Windows NT - Fix empty string case of inet_ntop() - vfork() wrapper now saves and restores errno - Update xsigaction() to yoink syscall support

Introduce native support for MacOS ARM64 There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues.

So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries.

# These flags cause GCC to predefine __STRICT_ANSI__. Please be warned
# that Cosmopolitan headers are written to comply with that request if
# it's possible to do so. Consider the following example:
#
# make -j12 -O o//tool/viz/printvideo.i
# clang-format-10 -i o//tool/viz/printvideo.i
# less o//tool/viz/printvideo.i
#
# You'll notice functions like memcpy(), ioctl(), etc. get expanded into
# wild-eyed gnu-style performance hacks. You can turn it off as follows:
#
# make -j12 -O MODE=ansi o/ansi/tool/viz/printvideo.i
# clang-format-10 -i o/ansi/tool/viz/printvideo.i
# less o/ansi/tool/viz/printvideo.i
#
# Here it becomes clear that ANSI mode can help you decouple your source
# from Cosmopolitan, by turning it into plain ordinary textbook C code.
#
# Another potential use case is distributing code to folks using tools
# such as MSVC or XCode. You can run your binary objects through a tool
# like objconv to convert them to COFF or MachO. Then use ANSI mode to
# rollup one header file that'll enable linkage with minimal issues.

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. https://justine.storage.googleapis.com/emulator625.mp4
