1 | Bugs Found And Fixed During Simulator Debug\r |
2 | \r | |
3 | 1. RP: drive clear does not clear RPDA.\r | |
4 | 2. TU: default formatter must be TM03.\r | |
5 | 3. SBI: drive 'letter' is actually a 1-based number.\r | |
6 | 4. MBA: drive register reads return SR<31:16> as high word.\r | |
7 | 5. UBA: DMA addresses must be masked to Unibus width (18b).\r | |
8 | 6. HK: thread used multiple times if SEEK is followed by NOP or DCLR.\r | |
9 | 7. HK: only DCLR clears ATA.\r | |
10 | 8. MEM: MS780E size declaration off-by-1.\r | |
11 | 9. MEM: MS780E array start off by >> 4.\r | |
12 | 10. MEM: CSR-C register write logic incorrect.\r | |
13 | 11. CIS: CMPP3/CMPP4 using wrong arguments to ReadDstr.\r | |
14 | 12. CPU, OCTA: CVTfi with integer overflow not setting trap if PSW<iv> = 1.\r | |
15 | 13. STDDEV: read of ICR was missing the call parameter.\r | |
16 | 14. ACBD/G: testing wrong operand register to get limit sign.\r | |
17 | 15. CPU: faults not clearing PSL<tp>.\r | |
18 | 16. ADAWI: register mode implemented incorrectly.\r | |
19 | 17. MOVTC: condition codes not preserved through page fault.\r | |
20 | 18. MOVTUC: condition codes not preserved through page fault.\r | |
21 | 19. MOVTUC: escape tested against untranslated rather than translated character.\r | |
22 | 20. CVTPT: condition code and decimal overflow calculation incorrect.\r | |
23 | 21. CVTPS: condition code and decimal overflow calculation incorrect.\r | |
24 | 22. CVTPL: if destination is register, result is stored after register updates.\r | |
25 | 23. CVTPL: integer overflow set <C> rather than <V>.\r | |
26 | 24. all decimal string: 11/780 does not validate characters in decimal strings.\r | |
27 | 25. EDITPC: condition codes not preserved through page fault.\r | |
28 | 26. EDITPC EO$INSERT: inserts sign instead of fill.\r | |
29 | 27. EDITPC EO$BLANK_ZERO: address off by one.\r | |
30 | 28. EDITPC EO$BLANK_ZERO: not testing for <C> set.\r | |
31 | 29. EDITPC EO$LOAD_PLUS: not skipping character if test fails.\r | |
32 | 30. EDITPC EO$LOAD_MINUS: not skipping character if test fails.\r | |
33 | 31. Compatibility mode: SXT not implemented.\r | |
34 | 32. Compatibility mode: XOR operands fetched in wrong order.\r | |
35 | 33. MNEGH: condition codes set from original sign.\r | |
36 | 34. MNEGH: <C> not cleared.\r | |
37 | 35. H_floating quad precision integer routines (add, inc, neg): carry propagation incorrect.\r | |
38 | 36. H_floating packup routines: test for zero used exponent not fraction.\r | |
39 | 37. MULH: carries out of floating accumulator lost.\r | |
40 | 38. DIVH: stores wrong operand as result.\r | |
41 | 39. POLYF/D/G: truncation after add not needed.\r | |
42 | 40. POLYF/D/G: early SRM requires truncation to 31b/63b, not 32b/64b.\r | |
43 | 41. POLYF/D/G/H: exits too early if argument is zero.\r | |
44 | 42. POLYD/G/H: calculates address of residual pointer result incorrectly.\r | |
45 | 43. POLYD/G: performs single precision rather than double precision multiply.\r | |
46 | 44. POLYH: fails to truncate intermediate result from 128b to 127b.\r | |
47 | 45. POLYF/D/G/H: internal add routine must test fraction rather than exponent to\r | |
48 | detect zero, POLYx can create "denormalized" intermediate result.\r | |
49 | 46. EMODH: concatenate 16b of extension operand instead of 15b.\r | |
50 | 47. Specifier flows: modify flows testing for read access rather than write access.\r | |
51 | 48. Quad/octa writes: wrong address reported on faulting cross-page writes.\r | |
52 | 49. Memory management: 11/780 implements access control test on first level PTE's.\r | |
53 | 50. LDPCTX: 11/780 implements mbz tests on PCB fields.\r | |
54 | 51. LDPCTX/MTPR: 11/780 validity checks PCBB, SCBB, SBR, SLR, P0BR, P0LR, P1BR, P1LR.\r | |
55 | 52. TMR: tmr_inc not updated in standard (100Hz) mode.\r | |
56 | 53. MTPR SBR/PCBB/SCBB: 11/780 only checks that bits<1:0> == 0.\r | |
57 | 54. MTPR xLR: 11/780 excludes bits<31:24> from mbz test.\r | |
58 | 55. MTPR PxBR: 11/780 only checks bits<31,1:0> == 1,00.\r | |
