2021-03-24AArch64: Add target description/feature for MTE registersLuis Machado1-1/+2
This patch adds a target description and feature "mte" for aarch64. It includes one new register, tag_ctl, that can be used to configure the tag generation rules and sync/async modes. It is 64-bit in size. The patch also adjusts the code that creates the target descriptions at runtime based on CPU feature checks. gdb/ChangeLog: 2021-03-24 Luis Machado <luis.machado@linaro.org> * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Take MTE flag into account.

2020-12-10[AArch64] SVE/FPSIMD fixup for big endianLuis Machado1-1/+0
The FPSIMD dump in signal frames and ptrace FPSIMD dump in the SVE context structure follows the target endianness, whereas the SVE dumps are endianness-independent (LE). Therefore, when the system is in BE mode, we need to reverse the bytes for the FPSIMD data. Given the V registers are larger than 64-bit, I've added a way for value bytes to be set, as opposed to passing a 64-bit fixed quantity. This fits nicely with the unwinding *_got_bytes function and makes the trad-frame more flexible and capable of saving larger registers. The memory for the bytes is allocated via the frame obstack, so it gets freed after we're done inspecting the frame. gdb/ChangeLog: 2020-12-10 Luis Machado <luis.machado@linaro.org> * aarch64-linux-tdep.c (aarch64_linux_restore_vreg) New function.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-1/+1
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix
