35 | ||
36 | * hw_trace.c (hw_trace_init_data): Delete. The trace options need | |
37 | to be initialized independant of the rest of the simulation | |
38 | initalization. Otherwize a trace option explictly set from gdb | |
39 | could be overridden by hw_trace. | |
40 | ||
41 | * psim.c (psim_options): Clarify reason why the trace ioctl occures. | |
42 | ||
43 | * FIXME: The trace code is too scattered - hw_trace.c, psim.c, | |
44 | debug.c. It could be much simpler. | |
45 | ||
46 | Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
47 | ||

49 | device so that it supports this. | |
50 | ||
51 | * device.c (device_add_string_array_property, | |
52 | device_find_string_array_property): New functions, manipulate | |
53 | properties containing an array of strings. | |
54 | (device_find_string_property): Allow a string array. | |
55 | (device_init_static_properties): Update. | |
56 | (device_init_runtime_properties): Update. | |
57 | ||
58 | * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk | |
59 | media. If no file image is specified, use the next one in the | |
60 | image property list. | |
61 | (hw_disk_init_address): Change the file property so that it is a | |
62 | string array - use the first entry for the initial file image. | |
63 | ||
64 | * tree.c (print_string_aray_property): New function - print a | |
65 | string array. | |
66 | (print_properties): Adjust. | |
67 | (print_string): Write a string, handling double quotes. | |

73 | ||
74 | * psim.c (psim_command): New function, parse more complex psim | |
75 | commands such as "change-media" and "trace". | |
76 | * sim_calls.c (sim_do_command): Use. | |
77 | ||
78 | Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
79 | ||
80 | * For expressions like (RA == 0) that are entered in to the cache | |
81 | as RA_is_0. If possible generate the result of the expression so | |
82 | that the compiler gets a better chance of eliminating dead | |
83 | branches. | |
84 | ||
85 | * gen-icache.c (print_icache_extraction): For a cache entry of | |
86 | the form <name>_is_<const> where it is a boolean field, generate | |
87 | the result of the expression instead of the expression its self. | |
88 | (print_icache_body): Remove code that was looking for *_is_0 and | |
89 | then generating corresponding definitions. | |
90 | ||
91 | * gen-icache.c (print_icache_struct): If there is no cache, do not | |
92 | output expressions in idecode.h file. | |

101 | Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |
102 | ||
103 | * The code that put values in and extracted values from the cache | |
104 | was too compilicated. The cache table did not allow values to be | |
105 | computed from cache entries. #defines could only be used when a | |
106 | cache was present, remove the restriction. | |
107 | ||
108 | * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A | |
109 | scratch variable is defined when a cache entry is beinf | |
110 | filled. Change the definition of a COMPUTE variable to be defined | |
111 | when the cache entry is being used. | |
112 | * gen-icache.c: Update. | |
113 | ||
114 | * ld-cache.h, ld-cache.c: Change field names so that their meaning | |
115 | is more obvious. old_name->field_name, new_name->derived_name. | |
116 | * gen-icache.c: Update | |
117 | ||
118 | * gen-icache.h, gen-icache.c (print_icache_body): Make the three | |
119 | different types of cache code - put into cache, extract from | |
120 | cache, no cache - an explicit argument to print_icache_body. | |
121 | * gen-icache.c (print_icache_extraction): Ditto. | |
122 | ||
123 | * gen-semantics.c (print_c_semantic): Update use. | |

125 | * gen-icache.c (print_icache_function): Update use. | |
126 | ||

128 | cache. | |
129 | ||
130 | * configure.in (enable-sim-icache): Clarify description. Make | |
131 | #define one of the defaults regardless of the cache. Probably | |
132 | should revamp and add a separate option. | |
133 | ||
134 | Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au> | |

145 | ||
146 | * The cap object was retaining a reference to the instance of a | |
147 | device after it was deleted. Instead add and remove cap's from the | |
148 | cap db as they are created and deleted. This ensuring that a | |
149 | capibility is only used during the lifetime of the corresponding | |
150 | object. | |
151 | ||
152 | * cap.h, cap.c: Correct cap type - was signed32 should be | |

163 | database. | |

184 | ||
185 | * The memory "claim" and "release" methods take an address and | |
186 | size as arguments. These may be multi cell values. Initially fix | |

1445 | ||
1446 | * gen-idecode.c (print_idecode_switch_illegal): Include a break | |
1447 | when generating illegal instructions. This was commented out | |

1491 | ||
1492 | * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and | |
1493 | hardware instead of checking it using ls. configure.in should | |
1494 | have taken care of any problems. | |

1505 | * configure.in (icache): Extend icache flag to include an insn | |
1506 | option. If specifyed the insn - aka instruction - is included in | |
1507 | the instruction cache. Make this the default. | |
1508 | * configure: re-generate. | |
1509 | ||
1510 | * igen.c (main), igen.h: Add option -S - inSn - for specifying | |

1536 | ||
1537 | * gen-idecode.c: Output the complete run_until_stop function | |
1538 | instead of just the code to handle a single instruction issue. | |
1539 | * : Have the generated idecode.c include inline.c (instead of psim.c). | |
1540 | ||
1541 | * std-config.h: Change psim.c so that it isn't inlined (as this is | |
1542 | no longer needed). | |
1543 | ||
1544 | * psim.c (run_until_stop): Delete the old run_until_stop function | |
1545 | instead calling the idecode_run and idecode_run_until_stop | |
1546 | functions that gen-idecode.c is now creating. | |
1547 | ||
1548 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
1549 | ||

1574 | ||

1576 | of ITRACE. The CPP line directives would have previously set the | |
1577 | line-nr and file name so ITRACE isn't needed. | |

1582 | idecode generation option. Instead of generating and calling | |
1583 | separate functions containing the semantic and icache code | |

1585 | indirect jump) to move between code blocks. | |

1588 | ||
1589 | * configure.in: New option --enable-sim-jump (default disabled) | |
1590 | ||

1596 | testing jumping idecodes. | |
