| | | | | After fixing bugs, checking alloc_ids now requires 9 instructions rather than 6.

| | | | | | | | Couple of typos in handle.subx. We didn't notice because a missing /r32 field gets turned into 0/EAX anyway, and because ECX happens to have the same value as EAX in the specific test caller. But it's still not running as expected, now that I'm looking closely.

| | | | | | | | | | We need yet another helper for computing the lengths of strings, while checking for escape sequences.

| | | | | | | | | | | | We're going to be cloning it for the length computation. Anytime we do something non-standard it's invariably short-lived.

| | | | | | | | | | Kind of a pathological case, but makes our loop follow a standard format, and provides some error checking at low cost.

| | | | | | | | | | | | | | | | | | | | | | | | I like to be able to jump between functions and tests using '}' in Vim :) We also shouldn't put the wrong argument types in the tabular columns. Just make it obvious they're not in use when instructions don't have a ModR/M byte. End-of-line comments are really only useful for instructions with a ModR/M byte.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now SubX defines headers with the following syntax: ``` === ... ``` The `...` can be either a numeric address or a name. Numeric addresses are useful for tests where we want to check addresses of individual instructions. Names are useful in real programs where we want to add to a segment in many places. This approach has long seemed a mess. It's hard to explain, and there's a certain amount of historical evolution that led to it that should be irrelevant to comprehend the current state of the codebase. I started out assuming the first segment was always code, before adding the special names 'code' and 'data'. We pretend to support more than two segments but we don't really. To simplify the code and explanation we'll move to a new syntax: ``` === <name> <address> ``` Code will always belong in the special name 'code', but it no longer has to be first. We need to migrate both our SubX-in-SubX phases and the C++ version. The plan is to start from the top down and update bootstrapping phases that've already been built (see commit 5102 for the list of phases). This commit updates pack.subx. Current state: ✓ hex.subx (no changes required) survey.subx ✓ pack.subx (fixed here) assort.subx dquotes.subx

| | | | | | | Clean up some old TODOs related to our pre-mmap limitations. Also caught another case of using the wrong comparison. When comparing addresses, one must always use unsigned rather than signed jump instructions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Still some failing tests: - emit-string-literal-data doesn't ignore metadata when computing the length of literal strings - emit-string-literal-data doesn't handle escape sequences One issue doesn't have a failing test: - emit-metadata doesn't handle string literals containing '/' All these open issues involve a common design question: how to parse a 'word' that includes a string literal that may include spaces. For everything else I know words can't contain spaces and datums can't contain slashes. But for string literals things are tougher.
