Bugs item #3407632, was opened at 2011-09-11 14:36 Message generated for change (Tracker Item Submitted) made by woody1234 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100599&aid=3407632&group_id=599 Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: z80 port Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Woody (woody1234) Assigned to: Nobody/Anonymous (nobody) Summary: dsp_bank1.c compiled wrong again Initial Comment: 1. Sample code attached. 2. Command line used: C:\SDCC\BIN\sdcc dsp_bank1.c -mz80 -c --oldralloc --std-c99 --codeseg CODE1 3. SDCC version tested: SDCC : mcs51/gbz80/z80/ds390/pic16/pic14/TININative/ds400/hc08 3.0.4 #6848 (Sep 10 2011) (MINGW32) 4. The code was compiled correct with build 6720 (as in attached dsp_bank1_6720.asm). It was correct no matter --oldalloc was used or not. And it goes wrong with build 6848 no matter --oldalloc is used or not. The bug is in sdcc.exe, put 6720 sdcc.exe into 6848 build will work correctly. By the way, the same function was compiled wrong with an earlier fixed bug report related with --max-allocs-per-node option. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100599&aid=3407632&group_id=599 |

Does it not terminate? Does it pass wrong values to one of the functions it calls? Does it assign wrong values to a global variable?

The code here related with load dsp code from program flash to internal memory, seemed that it was not correctly done. I will try to split the code more to figure out what exactly wrong later today. ---------------------------------------------------------------------- Comment By: Philipp Klaus Krause (spth) Date: 2011-09-12 20:21 Message: What exactly is the problem with the function?
