, and the feedback seemed supportive. As such, I am bringing a draft of
what I'm thinking will go into PEP 11 with a bunch of `XXX` placeholders
for people to help me fill in to see how this will look overall.
For any platform(s) you support, please reply with any relevant details
that should be added to the relevant tables below. Once I have these
details I will loop back with the proposed update to PEP 11 and make
sure everyone is still on board with the proposal.
A few remarks:
autoconf, GCC, and Debian call it "Target Triplet". Clang and Rust use
"Target Triple". Should we stick with the clang name or use the GCC name?
Target triplets are machine-vendor-os. They come in short, normalized
form and in long, extended form. The normalized form often omits the
vendor field. Your document has both long and short forms.
"wasm32-unknown-emscripten" is extended form for "wasm32-emscripten",
while "x86_64-windows-msvc" is the short form of
"x86_64-pc-windows-msvc". I recommend to stick to one convention.
By the way config.guess script and gcc can dump the current triplet. The
config.sub script can be used to normalize and validate a triplet (does
not work for MSVC). The output of config.guess is more specific than the
gcc machine info. Here is a dump from my RPi:
$ ./config.guess
armv7l-unknown-linux-gnueabihf
$ gcc -dumpmachine
arm-linux-gnueabih
$ ./config.sub arm-linux-gnueabihf
arm-unknown-linux-gnueabihf

It's a bit premature to add wasm32-wasi. Python doesn't even compile on
WASI yet.
