* 5436 - support newlines in dquotesKartik Agaram2019-07-211-8/+85
|
* 5435 - redo 5426Kartik Agaram2019-07-211-1/+1
| | | | | We can now translate layers 49-55 using translate and ntranslate. Next step is to support '\n' in dquotes.subx.
* 5430 - all examples passingKartik Agaram2019-07-201-4/+4
| | | | | We now have a new pass called 'tests' which code-generates a new function called 'run-tests', just like the C++ layer `tests.cc`.

* 5422Kartik Agaram2019-07-191-3/+3
| | | | | Various buffer sizes needed to be grown for ex11. But the next bottleneck is that we need to code-generate run-tests.
* .Kartik Agaram2019-07-101-2/+2
| | | | | Another batch of incorrectly signed conditional jumps. (Follow-up to commit 5180.)
* .Kartik Agaram2019-07-081-17/+17
| | | | | Be more consistent about names of ends of a slice. (In the opposite direction compared to last night's 925fc490d2ce8b8d411de87bd0af5b3a8a704213.)

| | | | Be more consistent about names of ends of a slice.
* .Kartik Agaram2019-07-081-30/+30
| | | | | | Move test slice variables out of the data segment and close to their usages. Makes tests a little easier to read even if we spend a few more instructions each time.
* Merge branch 'master' into surveyKartik Agaram2019-07-031-223/+872
|\ | | | | | | | | | | High time we pulled in the final changes to dquotes. In the process we fix one recently introduced duplicate symbol.

| | * dquotes now doneKartik Agaram2019-05-201-41/+162
| | | | | | | | | | | | | | | We need yet another helper for computing the lengths of strings, while checking for escape sequences.
| | * standardize the loop in skip-string-in-sliceKartik Agaram2019-05-201-5/+8
| | | | | | | | | | | | | | | | | | We're going to be cloning it for the length computation. Anytime we do something non-standard it's invariably short-lived.
| | * support string literals in emit-string-literal-dataKartik Agaram2019-05-201-11/+19
| | | | | | | | | | | | As expected, almost all tests now passing.
| | * support string literals in emit-metadataKartik Agaram2019-05-201-10/+31
| | |
| | * move local variable up following conventionsKartik Agaram2019-05-191-6/+11
| | | | | | | | | | | | | | | More importantly, don't mix reclaiming locals with discarding args after a call.
| | * convention: source arg in ESIKartik Agaram2019-05-191-8/+15
| | | | | | | | | | | | I _think_ we'll need to use it below. But may be wrong.
| | * handle words with just metadataKartik Agaram2019-05-191-3/+66
| | | | | | | | | | | | | | | Kind of a pathological case, but makes our loop follow a standard format, and provides some error checking at low cost.

| | | | | | | | | | | | I was missing a test to catch this.
| | * minor style cleanupKartik Agaram2019-05-181-34/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 5180Kartik Agaram2019-05-161-22/+12
| | | | | | | 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.
* complete the skeleton of dquotes.subxKartik Agaram2019-05-151-42/+98
| | | | | | | | | | | | | | | | 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.

* fix a stale register value in dquotes.subxKartik Agaram2019-05-141-1/+2
| | | | | | | | | | | | | How did things seem to be working until now? - We were saving an address from the stack to stream.read - When we read this address in skip-chars-matching:loop, we used to stop early But now we've moved the stack to a larger address, one where the most significant byte is set. When the stack address now gets to skip-chars-matching:loop, it's treated as a negative number and we proceed through the loop. At which point we try to index into the array using it. No real test to be written to protect against this :(
* Merge branch 'dquotes' into dquotes-1Kartik Agaram2019-05-131-1/+230
|\ | | | | | | | | dquotes.subx is now segfaulting after this merge. Seems to be trying to use addresses from the old stack.

| * | 5151 - use mmap everywhere we need a heapKartik Agaram2019-05-101-0/+24
| | | | | | | | | | | | | | | All tests passing now. Things are very explicit; before a program can `allocate` memory, it has to first obtain a segment from the OS using `new-segment`.

| | | | | | | | | | | | | | | Operations on buffered-file now always include the word 'buffered'. More verbose, but hopefully this highlights holes in the library.

|/ | | | | | | | | | | | | | | I'm switching to a more exposed working dynamic after chatting with Charles Saternos (https://github.com/akkartik/mu/pull/19). From now on I'll start a new branch for big features. Branches won't always pass all their tests. Phases have gone weeks in the past before being committed all at once. Developing in a branch gives others the opportunity to see more current progress and jump in more easily. Some 'kata' branches for new contributors to start at: * add two numbers: https://github.com/akkartik/mu/pull/21 * write a string to a byte stram: https://github.com/akkartik/mu/pull/22 * print a number in decimal to a byte stream: https://github.com/akkartik/mu/pull/20
