[LLVMdev] Seeking Tutorial Based on Generation of LLVM IR and static compilation

I'm writing a compiler (originally targeting x86 asm, but now)
LLVM IR. I am seeking some tutorial style information focused on:
1) Hand writing LLVM IR and/or compiler generated TEXT LLVM IR
text source modules by my compiler
2) Purely static compilation and linking of modules written in LLVM IR
(or compiler generated, clearly)
3) In sum, I'm only interested in using LLVM as a "high level assembler."
4) My RTS is written 90% in assembler (garbage collection, real coroutines,
dynamic control stack for exceptions, unwind-protect, fluid-variables,
lexically scoped non-local exits, etc.) - so an example of integrating
RTS code into such an "LLVM IR is a generic assembly language" type
project would be a god send.
To clarify further:
1) I have no interest whatsoever in all of LLVM's "JIT" oriented features
2) I have no interest in using a LLVM's C api to generate LLVM IR. My
compiler will generate TEXT files of LLVM IR source directly that will
then be "assembled and linked" statically by LLVM utilities.
I suppose ideally, I seek ONLY a tutorial on using LLVM IR as a source
language and then getting from there to a bunch of LLVM IR source
modules and from there to assembler/link.
LLVM is big, and I'd like to be able to learn just this "IR as generic
language" aspect of LLVM in a tutorial context.
I really, really, don't want to pay attention to all of LLVM's dynamic
compilation and C API features - which I don't need - if I can possibly
Any and all pointers to resources greatly appreciated.
Thanks in advance !!!
