2024-02-20gdb: pass frames as `const frame_info_ptr &`Simon Marchi1-2/+2
We currently pass frames to function by value, as `frame_info_ptr`. This is somewhat expensive: - the size of `frame_info_ptr` is 64 bytes, which is a bit big to pass by value - the constructors and destructor link/unlink the object in the global `frame_info_ptr::frame_list` list. This is an `intrusive_list`, so it's not so bad: it's just assigning a few points, there's no memory allocation as if it was `std::list`, but still it's useless to do that over and over. As suggested by Tom Tromey, change many function signatures to accept `const frame_info_ptr &` instead of `frame_info_ptr`. Some functions reassign their `frame_info_ptr` parameter, like: void the_func (frame_info_ptr frame) { for (; frame != nullptr; frame = get_prev_frame (frame)) { ... } } I wondered what to do about them, do I leave them as-is or change them (and need to introduce a separate local variable that can be re-assigned). I opted for the later for consistency. It might not be clear why some functions take `const frame_info_ptr &` while others take `frame_info_ptr`. Also, if a function took a `frame_info_ptr` because it did re-assign its parameter, I doubt that we would think to change it to `const frame_info_ptr &` should the implementation change such that it doesn't need to take `frame_info_ptr` anymore. It seems better to have a simple rule and apply it everywhere. Change-Id: I59d10addef687d157f82ccf4d54f5dde9a963fd0 Approved-By: Andrew Burgess <aburgess@redhat.com>
2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-10-04sme: Fixup sigframe gdbarch when vg/svg changesLuis Machado1-0/+5
With SME, where you have two different vector lengths (vl and svl), it may be the case that the current frame has a set of vector lengths (A) but the signal context has a distinct set of vector lengths (B). In this case, we may run into a situation where GDB attempts to use a gdbarch created for set A, but it is really dealing with a frame that was using set B. This is problematic, specially with SME, because now we have a different number of pseudo-registers and types that gets cached on creation of each gdbarch variation. For AArch64 we really need to be able to use the correct gdbarch for each frame, and I noticed the signal frame (tramp-frame) doesn't have a settable prev_arch field. So it ends up using the default frame_unwind_arch function and eventually calling get_frame_arch (next_frame). That means the previous frame will always have the same gdbarch as the current frame. This patch first refactors the AArch64/Linux signal context code, simplifying it and making it reusable for our purposes of calculating the previous frame's gdbarch. I introduced a struct that holds information that we have found in the signal context, and with which we can make various decisions. Finally, a small change to tramp-frame.c and tramp-frame.h to expose a prev_arch hook that the architecture can set. With this new field, AArch64/Linux can implement a hook that looks at the signal context and infers the gdbarch for the previous frame. Regression-tested on aarch64-linux Ubuntu 22.04/20.04.

2022-10-10Change GDB to use frame_info_ptrTom Tromey1-3/+3
This changes GDB to use frame_info_ptr instead of frame_info * The substitution was done with multiple sequential `sed` commands: sed 's/^struct frame_info;/class frame_info_ptr;/' sed 's/struct frame_info \*/frame_info_ptr /g' - which left some issues in a few files, that were manually fixed. sed 's/\<frame_info \*/frame_info_ptr /g' sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace problems. The changed files were then manually checked and some 'sed' changes undone, some constructors and some gets were added, according to what made sense, and what Tromey originally did Co-Authored-By: Bruno Larsen <blarsen@redhat.com> Approved-by: Tom Tomey <tom@tromey.com>

2014-12-03MIPS: Add support for microMIPS Linux signal trampolinesMaciej W. Rozycki1-0/+7
The necessity for this change has been revealed in the course of investigation related to proposed changes in the treatment of the ISA bit encoded in function symbols on the MIPS target. This change adds support for Linux signal trampolines encoded with the microMIPS instruction set. Such trampolines are used by the Linux kernel if compiled as a microMIPS binary (even if the binary run/debugged itself contains no microMIPS code at all). To see if we need to check whether the execution mode selected matches the given trampoline I have checked what the bit patterns of all the trampoline sequences decode to in the opposite instruction set. This produced useless or at least unusual code in most cases, for example: microMIPS/EB, o32 sigreturn, decoded as MIPS code: 30401017 andi zero,v0,0x1017 00008b7c dsll32 s1,zero,0xd MIPS/EL, o32 sigreturn, decoded as microMIPS code: 1017 2402 addi zero,s7,9218 000c 0000 sll zero,t0,0x0 However in some corner cases reasonable code can mimic a trampoline, for example: MIPS/EB, n32 rt_sigreturn, decoded as microMIPS code: 2402 sll s0,s0,1 1843 0000 sb v0,0(v1) 000c 0f3c jr t0 -- here the first instruction is a 16-bit one, making things nastier even as there are some other microMIPS instructions whose first 16-bit halfword is 0x000c and therefore matches this whole trampoline pattern. To overcome this problem I have decided the signal trampoline unwinder has to ask the platform backend whether it can apply a given trampoline pattern to the code location being concerned or not. Anticipating the acceptance of the ISA bit proposal I decided the handler not to merely be a predicate, but also to be able to provide an adjusted PC if required. I decided that returning zero will mean that the trampoline pattern is not applicable and any other value is the adjusted PC to use; a handler may return the value requested if the trampoline pattern and the PC requested as-is are both accepted. This changes the semantics of the trampoline unwinder a bit in that the zero PC now has a special value. I think this should be safe as a NULL pointer is generally supposed to be invalid. * tramp-frame.h (tramp_frame): Add `validate' member. * tramp-frame.c (tramp_frame_start): Validate trampoline before scanning. * mips-linux-tdep.c (MICROMIPS_INST_LI_V0): New macro.
