2023-07-21	sim/bpf: desCGENization of the BPF simulator	Jose E. Marchesi	1	-168/+0
	The BPF port in binutils has been rewritten (commit d218e7fedc74d67837d2134120917f4ac877454c) in order to not be longer based on CGEN. Please see that commit log for more information. This patch updates the BPF simulator accordingly. The new implementation is much simpler and it is based on the new BPF opcodes. Tested with target bpf-unknown-none with both 64-bit little-endian host and 32-bit little-endian host. Note that I have not tested in a big-endian host yet. I will do so once this lands upstream so I can use the GCC compiler farm.
2023-01-01	Update copyright year range in header of all files managed by GDB	Joel Brobecker	1	-1/+1
	This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-01-01	Automatic Copyright Year update after running gdb/copyright.py	Joel Brobecker	1	-1/+1
	This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-06-27	sim: bpf: fix mixed decls & code warnings (and style)	Mike Frysinger	1	-2/+5

2021-06-09	sim: bpf: use CURRENT_TARGET_BYTE_ORDER	Mike Frysinger	1	-1/+1
	Code should be going through this macro rather than accessing the underlying value directly.
2021-01-31	sim: bpf: fix mainloop extract call	Mike Frysinger	1	-1/+1
	The extract function takes the argbuf, not the scache.

	This commits the result of running gdb/copyright.py as per our Start of New Year procedure... gdb/ChangeLog Update copyright year range in copyright header of all GDB files.
2020-08-04	sim: eBPF simulator	Jose E. Marchesi	1	-0/+165
	This patch introduces the basics of an instruction-simulator for eBPF. The simulator is based on CGEN. gdb/ChangeLog: 2020-08-04 Jose E.
