| 2023-07-21 | sim/bpf: desCGENization of the BPF simulator | Jose E. Marchesi | 1 | -329/+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. | |||||
| 2022-11-02 | sim: common: change sim_{fetch,store}_register helpers to use void* buffers | Mike Frysinger | 1 | -2/+2 | |
| When reading/writing arbitrary data to the system's memory, the unsigned char pointer type doesn't make that much sense. Switch it to void so we align a bit with standard C library read/write functions, and to avoid having to sprinkle casts everywhere. | |||||
| 2022-10-31 | sim: reg: constify store helper | Mike Frysinger | 1 | -1/+1 | |
| These functions only read from memory, so mark the pointer as const. | |||||
| 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. | |||||
| 2021-06-28 | sim: bpf: fix printf warnings on 32-bit systems | Mike Frysinger | 1 | -1/+1 | |
| Use PRI macros to display 64-bit types instead of assuming long is a 64-bit type itself. | |||||
| 2021-06-27 | sim: bpf: include more local headers & fix broken funcs | Mike Frysinger | 1 | -9/+6 | |
| Various files were not including the relevant headers, or some funcs were missing prototypes entirely, leading to mismatch between the actual definition of the functions. Add includes to a few places and fix the broken functions that are uncovered as a result. Fixing some compile warnings (e.g. missing prototypes) often find real bugs. | |||||
| 2021-06-18 | sim: split sim-signal.h include out | Mike Frysinger | 1 | -0/+1 | |
| The sim-basics.h is too big and includes too many things. This leads to some arch's sim-main.h having circular loop issues with defs, and makes it hard to separate out common objects from arch-specific defs. By splitting up sim-basics.h and killing off sim-main.h, it'll make it easier to separate out the two. | |||||
| 2021-06-09 | sim: bpf: use CURRENT_TARGET_BYTE_ORDER | Mike Frysinger | 1 | -2/+2 | |
| Code should be going through this macro rather than accessing the underlying value directly. | |||||
| 2021-05-16 | sim: switch config.h usage to defs.h | Mike Frysinger | 1 | -0/+3 | |
| The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise. | |||||
