Hi!
I'm currently trying to retrieve the LLVM IR from the compilation process.
To do so, I followed the given instructions. From my perspective I'm not
missing anything, but I can't get llvm-goc to emit the llvm IR.
I created a transcript and added parameters to the the original call to
llvm-goc. Here is my fully modified script:
root@llvmbuilder-successful-s-1vcpu-2gb-fra1-01-s-1vcpu-2gb-fra1-01:~/compile/poc#
cat ./poc_transcript.sh
rm -r /tmp/go-build598282723
WORK=/tmp/go-build598282723
mkdir -p $WORK/b001/
cat >$WORK/b001/importcfg.link << 'EOF' # internal
packagefile

With the -S flag there is no dropped output or error message at all.
Omitting -S just drops the compiled object into the file given via the -o
flag. Here is the output of running my script:

Anyone got an idea how that happens?
Happy holidays! And thanks for your attention! :)
