gdb/ChangeLog:
Update copyright year range in all GDB files
|
|
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.

gdb/ChangeLog:
Update year range in copyright notice of all files.
|
|
|
|
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.

uninterpreted formats. If fmt is one of the uninterpreted types
don't update the FPR_STATE. Handle fmt_uninterpreted_32 like
fmt_word, and fmt_uninterpreted_64 like fmt_long.
(store_fpr): When writing an invalid odd register, set the
matching even register to fmt_unknown, not the following register.
* interp.c (sim_open): If STATE_MEM_SIZE isn't set then set it to
the the memory window at offset 0 set by --memory-size command
line option.
(sim_store_register): Handle storing 4 bytes to an 8 byte floating
point register.
(sim_fetch_register): Likewise for reading 4 bytes from an 8 byte
register.
(sim_monitor): When returning the memory size to the MIPS
application, use the value in STATE_MEM_SIZE, not an arbitrary
hardcoded value.
(cop_lw): Don' mess around with FPR_STATE, just pass
fmt_uninterpreted_32 to StoreFPR.
(cop_sw): Similarly.
(cop_ld): Pass fmt_uninterpreted_64 not fmt_uninterpreted.
(cop_sd): Similarly.
* mips.igen (not_word_value): Single version for mips32, mips64
and mips16.
