1243 Make the simulator compatible with the MPC750. It would be nicer
1244 to make this a real multi-sim, but that's more work than we have
1245 time for.
1246 * emul_generic.c (emul_add_tree_options): Only require strict
1247 alignment if it was explicitly requested at configuration time.
1248 Don't make it the default for little-endian machines.
1249 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1250 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1251 THRM2, THRM3): Plop in the MPC750 SPR registers.
1252 (DABR): This is weird. This was HID5, but the PPC spec says this
1253 should be DABR; why did some random processor use it for something
1254 else? The HID5 entry dates back to the original checkin of the
1255 simulator code in 1995, so remove it.
1256 * sim_calls.c (register_names): Delete this; since the user can
1257 now change GDB's list of register names dynamically, we can't
1258 pretend there's a static mapping here.
1259 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1260 function to get the register name. That ought to be accurate.
1261 However, we're changing a compile-time dependency (using the
1262 REGISTER_NAMES macro) into a link- and run-time dependency
1263 (calling REGISTER_NAME, which happens to be a function call on the
1264 PPC).
1265
12661999-01-22 Jim Lemke <jlemke@cygnus.com>
1267
1268 * igen.c(gen_semantics_[ch]): setup/use of new option

1296Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1297
1298 * table.c (table_open): For cygwin hosts, we need to use the
1299 return value from the read routine as the number of bytes to
1300 process. This apparently is due to text-mode vs binary-mode. If
1301 the mounts are done text-mode, then the size returnedby fstat()
1302 may be different than the number of bytes "read" in text mode.

c906108c
SS		 1668 * gen-icache.c (print_icache_extraction): Add a reason parameter.

1674
1675 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1676 works for normal and boolean table entries.
1677
1678 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1679 valid. Handle this just like *_{read,write}_register now handles

1694
1695 * gen-idecode.c: Re-work the table lookup code so that it assumes
1696 that the entry is a leaf by default. Simplify the boolean table
1697 entry code so that it involves a mask + test instead of shift +
1698 shift + mask + test.
1699

1701 or doubles clock interrupts.

1730 fields.
72f4393d 1731
c906108c
SS		 1732 * misc.c (name2i): Possibly abort if an invalid name is

72f4393d 1741
c906108c
SS		 1742 * psim.c (psim_write_register, psim_read_register): Force the cpu
1743 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1744 next cpu would be zero any way.
1745
1746 * mon.c (mon_print_info): If possible, print the system cycle
1747 performance. This is an indication of the number of instructions
1748 per second.
1749
1750Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1751
1752 * The code to allow an event queue to be updated during a signal
1753 was missing. For main.c, a cntrl-c simulation termination wasn't
1754 handled cleanly.
72f4393d 1755
c906108c
SS		 1756 * The simulation would not correctly restart if an event requested
1757 that the simulation be halted.
72f4393d 1758
c906108c
SS		 1759 * psim.c (psim_options): Add hack to -i option to optionally

1776 false.

1790
1791 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1792 RA. Based on instruction frequency stats, expand additional
1793 instructions.

72f4393d 1795
c906108c

1808
1809 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1810 to be initialized independant of the rest of the simulation
1811 initalization. Otherwize a trace option explictly set from gdb
1812 could be overridden by hw_trace.
1813
1814 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1815
1816 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1817 debug.c. It could be much simpler.
1818

72f4393d 1820

1835 string array - use the first entry for the initial file image.
1836
1837 * tree.c (print_string_aray_property): New function - print a
1838 string array.

1851Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1852
1853 * For expressions like (RA == 0) that are entered in to the cache
1854 as RA_is_0. If possible generate the result of the expression so
1855 that the compiler gets a better chance of eliminating dead
1856 branches.
1857
1858 * gen-icache.c (print_icache_extraction): For a cache entry of
1859 the form <name>_is_<const> where it is a boolean field, generate
1860 the result of the expression instead of the expression its self.
1861 (print_icache_body): Remove code that was looking for *_is_0 and
1862 then generating corresponding definitions.
1863
1864 * gen-icache.c (print_icache_struct): If there is no cache, do not
1865 output expressions in idecode.h file.

1874Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1875
1876 * The code that put values in and extracted values from the cache
1877 was too compilicated. The cache table did not allow values to be
1878 computed from cache entries. #defines could only be used when a
1879 cache was present, remove the restriction.
1880
1881 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1882 scratch variable is defined when a cache entry is beinf
1883 filled. Change the definition of a COMPUTE variable to be defined
1884 when the cache entry is being used.
1885 * gen-icache.c: Update.
72f4393d 1886
c906108c
SS		 1887 * ld-cache.h, ld-cache.c: Change field names so that their meaning

c906108c
SS		 1891 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1892 different types of cache code - put into cache, extract from
1893 cache, no cache - an explicit argument to print_icache_body.

1901 cache.
1902
1903 * configure.in (enable-sim-icache): Clarify description. Make

1908

1918
1919 * The cap object was retaining a reference to the instance of a
1920 device after it was deleted. Instead add and remove cap's from the
1921 cap db as they are created and deleted. This ensuring that a
1922 capibility is only used during the lifetime of the corresponding
1923 object.
72f4393d 1924
c906108c
SS		 1925 * cap.h, cap.c: Correct cap type - was signed32 should be

1957
1958 * The memory "claim" and "release" methods take an address and
1959 size as arguments. These may be multi cell values. Initially fix
1960 the memory code so that they check/detect this. Leave the
1961 adjustment of any clients to later.

c906108c
SS		 1963 * hw_memory.c (hw_memory_instance_claim,
