  • 0c161a6cdd Now that cc65 programs can run as SYS files themselves my ProDOS Loader ulimately has to change from a minimalistic shell replacement to a pure loader (without exit hook). This approach simplifies several things. However the "reboot after exit" option now present as a ProDOS Loader variant has to move into the cc65 program. ol.sc 2009-09-14 19:58:06 +00:00
  • 29cea09e0d Removed debug output uz 2009-09-14 19:56:47 +00:00
  • d451248437 Fixed another problem with OptJumpTarget1, that was mostly prevented from being triggered by other optimizations, which removed or changed the trigger code. uz 2009-09-14 19:54:50 +00:00
  • 254e1169f2 Fixed a problem with OptJumpTarget1: The inspected jump must not have a label attached, because the effective code changes for code jumping to this label if removals are applied. uz 2009-09-14 18:36:38 +00:00
  • b7df1ed5d4 Being loaded by my 'ProDOS Loader' needs to be classified as being loaded as BIN from an interpreter (and not as SYS). But the 'ProDOS Loader' zeros the system bitmap up to the system global page (this is what it's about) so additionally check page $03 protection which is zero when loaded as SYS but one when loaded by 'ProDOS Loader 1.4'. ol.sc 2009-09-13 19:50:09 +00:00

  • 773e05b5f3 Removed '_' prefix from textframe(xy) because this prefix for non-standard symbols isn't necessary if they are declared in non-standard include files. ol.sc 2009-09-10 19:18:15 +00:00
  • d91fe6b877 ProDOS 8 requires an page-aligned 1kB IO-buffer for every open file. The implementation using posix_memalign() is universally correct but quite expensive. There I added support for overriding this implementation with maybe limited (i.e. to one open file) but cheaper custom implementations. ol.sc 2009-09-10 09:59:26 +00:00

  • 648a1b5427 Added support for switching between 40/80 columns. As the Apple //e 80 column firmware features converting the current screen content on switching if was already active before the idea is to keep the 80 column firmware active and initialize it (which clears the screen) only if necessary. ol.sc 2009-09-10 09:04:05 +00:00

  • 2d3b0f1146 Fixed a problem similar to the one in Assignment() some time ago: An expression that yields a constant value may have side effects, and the expression code must not be removed in this case. uz 2009-09-08 20:08:21 +00:00

  • f5ca779b9b A constant right side does not necessarily mean that no code is generated for the right side. The expression may have had side effects. This error is also found in several other places. uz 2009-09-07 14:22:27 +00:00
  • b2d30c3283 Remove stack pointer check in RemoveCodeRange - the calling function has to take care about that. uz 2009-09-07 14:21:19 +00:00
  • 96b731dd96 Just presume alternate charset to be active on the //e - how shouldn't it if conio usage activates it. ol.sc 2009-09-07 14:00:17 +00:00

  • 18d865e609 Fixed another problem with OptStackOps: Load tracking will not work across branches - if we find a label, just forget all information we had before. uz 2009-09-04 19:54:29 +00:00
  • f6c589bf8e Fixed problems with OptPrecalc. It removed insns because it results were known - but the insns generate a carry which may be needed later. uz 2009-09-04 15:44:48 +00:00
