You are right, I removed the IONFILTER part. Moreover, I had to add the option --ion-eager to get something in the output files.
Finally, I have used the option --compileonly to compile but not run the code. My final command is: $ IONFLAGS=logs,scripts,osi,bailouts ./js --ion-offthread-compile=off --compileonly --ion-eager /shared/pure.js 2>&1 Thanks a lot for your help.
