X-Git-Tag: V2.15~51 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2c975d36424c4d04e998f8f8b1633ad56ed9476a;p=cc65 Create static drivers directly from source files. Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach: The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory. However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails. Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac'). --- diff --git a/asminc/module.mac b/asminc/module.mac new file mode 100644 index 000000000..d844ec104 --- /dev/null +++ b/asminc/module.mac @@ -0,0 +1,13 @@ +.ifndef DYN_DRV + DYN_DRV = 1 +.endif + +.macro module_header module_label + .if DYN_DRV + .segment "HEADER" + .else + .data + .export module_label + module_label: + .endif +.endmacro diff --git a/doc/ca65.sgml b/doc/ca65.sgml index b222b4aac..32cf0b80b 100644 --- a/doc/ca65.sgml +++ b/doc/ca65.sgml @@ -4321,16 +4321,14 @@ The package defines the following macros: .MACPACK atari
