17:30:25 drmeister Hello

17:30:32 drmeister clhs file-length

17:51:15 kpoeck Hello

17:51:34 drmeister Howdy

17:51:37 kpoeck we also have ext:stat

17:52:05 kpoeck for trivial-file-size

17:52:36 drmeister Ah - thanks. This is code that is really early in the build process. The problem wasn't file-length - it was that I didn't have WHEN.

17:53:32 drmeister I've got the CLASP_BUILD_MODE "fasoll" working now for quicklisp. Building quicklisp systems creates files with the faspll extension.

17:53:41 drmeister The file contains human readable llvm-ir.

17:54:09 kpoeck one file per system?

17:58:15 drmeister one file per source file.

17:58:33 drmeister Like normal - but instead of a .fasl or .fasp you get a .faspll

17:58:46 drmeister We can build a bunch of different ways not.

17:58:51 drmeister .o -> .so/.dylib

17:58:55 drmeister .faso -> .fasp

17:59:01 drmeister .fasoll -> .faspll

17:59:07 drmeister .fasobc -> .faspbc

18:00:22 drmeister s/different ways not/different ways now/

18:25:52 drmeister I'll make sure faso mode still works and then I'll push it.

18:26:08 drmeister Next I'm going to try and get thread sanitizer working.

18:26:59 drmeister I figured that I needed to be able to generate llvm-ir for all of the common lisp code before I tackled thread sanitizer because I don't want Cando building itself under the thread sanitizer - that would take an insane amount of time.

20:08:09 drmeister Dangnabbit! I just realized why I can't link modules from separate threads in compile-file-parallel!

20:08:33 drmeister There is a different LLVMContext for each thread - the modules basically live in separate parallel universes.

20:09:59 drmeister You can't mix goats and alpacas.

20:10:38 drmeister I have to stream out the llvm-ir to a memory buffer and then read it back in into one thread.

22:10:21 drmeister Yeah - in compile-file-parallel each thread now generates an llvm-ir source file in a string and then the main thread parses them back into modules and links them together.

22:10:42 drmeister That works.

22:11:38 drmeister So now - with the fasoll CLASP_BUILD_MODE compile-file-parallel generates an llvm-ir file that we can examine to see what it is generating.

22:11:49 drmeister If there are code generation errors - that's where we can look for them.
