It also wouldn't be crazy for the `nim c` / `nim cpp` compiler drivers to
accept some sample program invocation and do the program - sample-run -
re-compile three stage process more automatically, but that isn't in place
either. My `nim-pgo` script just assumes the usual `~/.cache/nim/r` locations I
mentioned. The short of my script is:
nim $be -c --cc:gcc -d:release -d:danger $nimOpts "$prog.nim" || exit 1
inputs=$(echo $nimcache/*.c*)
$cc -fprofile-generate $inputs -o $prog $ccL || exit 1
rm -f *.gcda
eval "$cmd"
$cc -fprofile-use $inputs -o $prog $ccL
Run
but I also echo some things like PWD and set up those `$` environment vars.
