Oh, one important thing I forgot to mention: that patch is for LLVM 16
only, and I developed it with a local build of their "release/16.x"
branch on a FreeBSD box, and also tested with a released package for
16 on a Debian box. Further changes are already needed for their
"main" branch (LLVM 17-to-be), so this won't quite be enough to shut
seawasp up. At a glance, we will need to change from the "old pass
manager" API that has recently been vaporised[1]
(llvm-c/Transforms/PassManagerBuilder.h) to the new one[2][3]
(llvm-c/Transforms/PassBuilder.h), which I suspect/hope will be as
simple as changing llvmjit.c to call LLVMRunPasses() with a string
describing the passes we want in "opt -passes" format, instead of our
code that calls LLVMAddFunctionInlingPass() etc. But that'll be a
topic for another day, and another thread.
