Todo:
fasl.tex
In good shape.
object.tex
Fairly good, but should probably be integrated with description of primitives
in vm.tex.
front.tex
Needs updating cleanup scan. Not too bad.
middle.tex
Need VMR overview. New names for GTN/LTN? Needs general cleanup, but not too
bad. NLX and stack are the worst.
back.tex
Pack and assembler need more info. General cleanup.
compiler-overview.tex
Adapt introductory material from /../fred/usr/ram/comp.mss, pap:talk.mss
Division between ICR overview and ICR convert needs work.
debugger.tex
Needs much work. Merge much info from debug-info and debug-int. Duplicating a
fair amount of stuff in the source may make sense where, since this is a part
of the system that is generally interesting. And also, a part that people
building on CMU CL might want to understand.
glossary.tex
Finish, integrate w/ main text?
interpreter.tex
Very sketchy and tentative. Needs to be fleshed out from the code.
retargeting.tex
Very rough. Needs to be merged with parts of vm.tex (call vops). Needs some
additional text. Documentation of assembler, and all other exported
interfaces. (Generate defined VOP descriptions from the core, keyed to files?)
vm.tex
This file should probably cease to exist, going into object, retargeting and
introductory material. [Also other scrap in stuff/]
[VMR and ICR overview also needed...]
architecture.tex
Missing sections on startup code, compiling, building.
environment.tex
Needs to be written: type system and info database interfaces.
interface.tex
Needs to be written: source paths and error message utilities.
lowlev.tex
Needs to be written. All manner of low-level stuff: memory layout and
management, core file format, C interface, low-level debugging (and ldb.)
Several different audiences:
-- Curious compiler implementors (not a big priority. Downplay academic
aspects, i.e. comparisons to other techniques, analysis of limitations,
future work...) Compiler part can be more academic, and include some
justifications of other design decisions.
-- System maintainers.
-- People retargeting the compiler.
-- People bringing up the system in a new environment.
Sys arch part:
Package + file structure [system.txt]
system building [compiling.txt]
bootstrapping & cross compiling
Compiler design:
Overview (mirror structure of rest of the part)
ICR data structure
Front end [front.tex]
Basic VMR data structures (no back-end stuff)
Middle end [middle.tex]
Back end + data structures [back.tex]
Error system interface
Source tracking
Compiler retargeting:
VM definition concepts [porting.txt, mail.txt, retargeting.tex]
SCs, SBs, primitive-types
Defining VOPS
time specification
defining
and using the assembler
Required VOPs [internal.txt, lowlev.txt, vm.mss]
Standard primitives [vm.mss] (broken down by type, parallels object format
section structure.)
Customizing VMR conversion
multiple hardware
constant operands
VM specific transforms
special-case IR2 convert methods
Run-time system:
type system
info database
Data format [object.tex]
Debugger:
Info format [debug.txt]
Stack parsing [debug.txt]
Breakpoints
Internal errors
Signals
Memory management: [William]
heap Layout
stacks
GC
misc implementation stuff: foreign call, assembly routines [lowlev.txt]
LDB and low-level debugging
core file format [William]
fasl format [fasl.tex]
