Devine Lu Linvega f348d24606 Removing rawchr run 2022-08-14 12:06:23 -07:00
Devine Lu Linvega ef30fb8f8e Removed JSR JMP2r tail-call optimisations for now 2022-08-06 11:05:16 -07:00
Andrew Alderwick 978713474a (uxnasm) Prevent tail call optimisation when required, fixes asma 
Literals do not get squashed across absolute or relative pads and
labels, now the tail call optimisations do not occur under the same
conditions. etc/asma-test.tal was identifying serious errors with
asma.rom, which uses "JSR2 &skip JMP2r" in @asma-macro-body.

phoebos a014cd8da9 (uxnasm) only ignore [ or ] if it is a whole token 
Currently, tokens beginning with a [ or ] character are completely
ignored, which forbids a macro from beginning with these characters.
Specifically, a macro can be declared eg. as `%[x { ... }` but cannot be
dereferenced as `[x`.
This patch only ignores these tokens if they have a length of 1;
otherwise the switch falls through to the default case.

Andrew Alderwick c2ffe63cc3 (uxnasm) Fix valid macro names being rejected. 
Macro names that begin with the name of an opcode were being rejected
incorrectly. “STA” would not be a valid macro name since it is an
opcode, but “STACK” should be fine.

Erik Osheim abd6a3a5da Support nested comments in uxnasm. 
Previously, code like this would fail with an error
about an unrecognized ) token:

    ( this is a ( nested ) comment )

With this patch, the above code will now work.

Relatedly, it was previously possible to write code
that compiled but was confusing:

    (open parenthesis should have a space )
    ( in this case the ADD2 will be ignored )ADD2
    ( this comment with ( would have been fine )

With this commit, the first example will emit a warning
but continue to work as intended. The second and third
examples will continue searching for a matching ) token,
which due to the new nested coment behavior will probably
mean the rest of the file gets commented out.
