Known issues

1. I had to patch llvm-bindings in a few places. Not all of them have been released yet. E.g. see ApsarasX/llvm-bindings#23.

Some common commands

Assembly to bitcode:

llvm-as x.ll
ls -l x.bc

To compile .ll to machine code:

llc x.ll -filetype=obj
gcc x.o
./a.out

To run optimizer:

opt -Oz -S -o x.Oz.ll x.ll
# --metarenamer - rename everything

To WASM:

llc -mtriple=wasm32-unknown-unknown -O3 -filetype=obj one.ll -o one.o
wasm-ld one.o -o one.wasm -allow-undefined --entry "main"

To see WAT (see wabt):

wasm2wat -o one.wat one.wasm
