This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
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.
* cpustate.c (aarch64_get_FP_half): New function. Read a vector
register as a half precision floating point number.
(aarch64_set_FP_half): New function. Similar, but for setting
a half precision register.
(aarch64_get_thread_id): New function. Returns the value of the
CPU's TPIDR register.
(aarch64_get_FPCR): New function. Returns the value of the CPU's
floating point control register.
(aarch64_set_FPCR): New function. Set the value of the CPU's FPCR
register.
* cpustate.h: Add prototypes for new functions.
* sim-main.h (struct _sim_cpu): Add FPCR and tpidr fields.
* memory.c: Use unaligned core access functions for all memory
reads and writes.
* simulator.c (HALT_NYI): Generate an error message if tracing
will not tell the user why the simulator is halting.
(HALT_UNREACHABLE): Delete. Delete (unneeded) uses of the macro.
(INSTR): New time-saver macro.
(fldrb_abs): New function. Loads an 8-bit value using a scaled
offset.
(fldrh_abs): New function. Likewise for 16-bit values.
(do_vec_SSHL): Allow for negative shift values.
(do_vec_USHL): Likewise.
(do_vec_SHL): Correct computation of shift amount.
(do_vec_SSHR_USHR): Correct decision of signed vs unsigned
shifts and computation of shift value.
(clz): New function. Counts leading zero bits.
(do_vec_CLZ): New function. Implements CLZ (vector).
(do_vec_MOV_element): Call do_vec_CLZ.
(dexSimpleFPCondCompare): Implement.
(do_FCVT_half_to_single): New function. Implements one of the
FCVT operations.
(do_FCVT_half_to_double): New function. Likewise.
(do_FCVT_single_to_half): New function. Likewise.
(do_FCVT_double_to_half): New function. Likewise.
(dexSimpleFPDataProc1Source): Call new FCVT functions.
(do_scalar_SHL): Handle negative shifts.
(do_scalar_shift): Handle SSHR.
(do_scalar_USHL): New function.
(do_double_add): Simplify to just performing a double precision
add operation. Move remaining code into...
(do_scalar_vec): ... New function.
(dexLoadUnsignedImmediate): Call new fldrb_abs and fldrh_abs
functions.
(system_get): Add support for TPIDR, CTR, FPCR, FPSR and CPSR
registers.
(system_set): New function.
(do_MSR_immediate): New function. Stub for now.
(do_MSR_reg): New function. Likewise. Partially implements MSR
instruction.
(do_SYS): New function. Stub for now,
(dexSystem): Call new functions.
