[Docs] Enumerate all supported target features for compiler options in man pages
Where is the problem?
mojo build --target-features
What can we do better?
支持哪些枚举，我希望在ubuntu 上 做树莓派的交叉编译 ，armv7l
Anything else?
No response
Thanks for your question! We definitely should improve the documentation here on which targets are supported in the compiler.
I don't know all the specifics right now, but I do know that we currently do not support 32-bit ARM architectures, which armv7 is.
From the build documentation I see that I can specify --target-triple <TRIPLE>
What are the allowed triples? Are they similar to clang’s?
“The triple has the general format <arch><sub>-<vendor>-<sys>-<env>, where:
arch = x86_64, i386, arm, thumb, mips, etc.
sub = for ex. on ARM: v5, v6m, v7a, v7m, etc.
vendor = pc, apple, nvidia, ibm, etc.
sys = none, linux, win32, darwin, cuda, etc.
env = eabi, gnu, android, macho, elf, etc.”
Is there somewhere in the source code that I can find it?
For anyone who also search for the list of target-features, you can get them by running this command:
llc -march=[TARGET_ARCH] -mattr=help
And if you have rust installed you also can run:
rustc --print=target-features for --target-features
rustc --print=target-cpus for --target-cpu
rustc --print=target-list for --target-triple
