This is done to remove confusions among potential debugger users and to also make it more accurately tell what this feature is actually doing. Despite being true that it is using a memcheck (and it certianly checks that memory), the idea being to break on a memory access isn't really obvious especially considering that memchecks are also used in full MMU emulation to handle exceptions. It also doesn't help that memchecks are now supported in every builds.
It also changes the corresponding log because this log would be wanted by the user which means it should be more obvious that it was caused by the "memory breakpoint".
Changes:
- MemoryWindow was cleaned up and gives more feedback on searches.
Some bugs were fixed as well:
- A complex bug that allowed tearing off tabs and opening multiple
copies of a debug panel which lead to segfaults
- Another segfault related to right-click menus on code/memory views
when those tools were floating in their own window.
There was a bug that caused MemoryView to indirectly cause a segfault;
the simplest way to reproduce it is 1) start a game; 2) stop the game;
3) click on the Refresh button and watch Dolphin segfault.
This commit fixes it by only calling PowerPC::HostIsRAMAddress when
emulation is running.
Considering there's a public method in the class using it, leaving the
definition in the cpp file can cause a linker error if any method outside
that cpp file calls it for one reason or another.
Single step: Fix an oddity when a breakpoint is hit at the beginning of a block, then after, a single step is performed and finally, hitting play, the breakpoint will be skipped even in the case when it would be hit again. This was done by using the interpreter version of single step. Also, remove some redundant update request.
Step over: fix some GUI lags.
Step out: Add consideration for conditional branching by checking the condition as the interpreter does. Now, every bclr instructions except those that changes the LR (because it would not be the end of the function) will cause the end of the step out and not just blr instructions. Also now stops if a bp is detected and finally, remove redundant GUI updates calls.
This also removes a superfluous draw call on the GUI as the codeView was refreshing twice per event to do so.
The old one wasn't very optimal because not only the user would likely want to enter an address instead of a range, but it also made entering just one address confusing (you had to have the same value on both start and end). Also, you should only chose one option between read, write or both, there is no point to not have any.
This is why I made more clear how to add an address and it is the default option using radio buttons and I also made the action flags and the flags to be radio buttons.
There might be a better way to highlight the options when adding the memory check, but for now, this works and the breakpoint list reports the right settings anyway.
It wouldn't impact performance until at least one memcheck is enabled. Because of this, it can be used in release builds without much impact, the only thing that woudl change is the use of HasAny method instead of preprocessor conditionals. Since the perforamnce decrease comes right when the first memcheck is added and restored when the last is removed, it basically is all beneficial and works the same way.
All formatting are individual per registers and they all have one option to go back to their original hexadecimal form.
- GPR: signed integer, unsigned integer, float
- FPR: double
Also happened to come accross an issue where editing the PFR would ignore the higher 32 bits of the new value, this had to be fixed for the format to work.
This removes a Dolphin-specific patch to the wxWidgets3 code
for the following reasons:
* Calling wxWindowGTK::DoSetSize on a top-level window can end up
calling wxTopLevelWindowGTK::DoMoveWindow, which triggers an assert
because it is not supposed to be called for a top-level wxWindow.
* We should not be patching the wxWidgets code because that means the
toolbars will still be broken if someone builds without using the
WX that is in our Externals.
Instead, we now use a derived class for wxAuiToolBar and override
DoSetSize() to remove the problematic behaviour to get the same effect
(fixing toolbars) but without changing Externals code and without
causing asserts and other issues.
For step over, it was updating twice which actually made the red display on the register view (when a register changes since) malfunction. Since it doesn't seem to be usefull to update before AND after the run, the one before the run was removed.
For step out, well, because there was no chances given for the thread to run as it is single stepping all the time, I only added a call to update after it was done.
Both those in the code window and the ones that appears when the user select edit perpective. The one that isn't fixed by this is in edit perspective mode, when the user drags a panel out and it becomes a floating window.
Add the CCodeWindow to the constructor of the memoryWindow so it can call the notify update of the breakpoint list.
Add the case of breakpoint update when receiving an event (the update command was issued, but wasn't managed before).
Run clang format and renamed the code window names.
From wxWidgets master 81570ae070b35c9d52de47b1f14897f3ff1a66c7.
include/wx/defs.h -- __w64 warning disable patch by comex brought forward.
include/wx/msw/window.h -- added GetContentScaleFactor() which was not implemented on Windows but is necessary for wxBitmap scaling on Mac OS X so it needs to work to avoid #ifdef-ing the code.
src/gtk/window.cpp -- Modified DoSetClientSize() to direct call wxWindowGTK::DoSetSize() instead of using public wxWindowBase::SetSize() which now prevents derived classes (like wxAuiToolbar) intercepting the call and breaking it. This matches Windows which does NOT need to call DoSetSize internally. End result is this fixes Dolphin's debug tools toolbars on Linux.
src/osx/window_osx.cpp -- Same fix as for GTK since it has the same issue.
src/msw/radiobox.cpp -- Hacked to fix display in HiDPI (was clipping off end of text).
Updated CMakeLists for Linux and Mac OS X. Small code changes to Dolphin to fix debug error boxes, deprecation warnings, and retain previous UI behavior on Windows.
Fix Frame Advance and FifoPlayer pause/unpause/stop.
CPU::EnableStepping is not atomic but is called from multiple threads
which races and leaves the system in a random state; also instruction
stepping was unstable, m_StepEvent had an almost random value because
of the dual purpose it served which could cause races where CPU::Run
would SingleStep when it was supposed to be sleeping.
FifoPlayer never FinishStateMove()d which was causing it to deadlock.
Rather than partially reimplementing CPU::Run, just use CPUCoreBase
and then call CPU::Run(). More DRY and less likely to have weird bugs
specific to the player (i.e the previous freezing on pause/stop).
Refactor PowerPC::state into CPU since it manages the state of the
CPU Thread which is controlled by CPU, not PowerPC. This simplifies
the architecture somewhat and eliminates races that can be caused by
calling PowerPC state functions directly instead of using CPU's
(because they bypassed the EnableStepping lock).
The dumb wxAUI stuff isn't fully implemented for GTK. So the wxAuiToolBar doesn't properly deduce the size it needs to be when it contains a
wxSearchCtrl object.
Force the manager to set its minimum size to something reasonable.
Using the XPM format for images has become a maintenance problem because
people don't know how to create them. This commit removes all XPM images
and all C files that contain PNG images. DolphinWX now uses the PNGs
in the Resources folder instead, just like DolphinQt and DolphinQt2 do.
This cleans up some of the code between core and UI for disassembling and dumping code blocks.
Should help the QT UI in bringing up its debug UI since it won't have to deal with this garbage now.
Technically the fallthrough would never happen, as the row numbers correspond to the grid view (which will always be zero or greater). However, it gets rid of compiler warnings on higher warning levels.
On OS X, this broke Cmd-V to paste in the text boxes. Apparently wx
thinks having mnemonics (which are Alt-* on Windows) be Cmd-* on OS X,
even if this disables standard shortcuts, is a good idea.
Lioncash suggested just getting rid of the accelerators on non-menu
controls, so I'm doing that rather than disabling them only on OS X.
1) Apparently wxString::Format is type safe, and passing a u32 to it
with the format "%lu" crashes with a meaningless assertion failure.
Sure, it's the wrong type, but the error sure doesn't help...
2) "A MenuItem ID of Zero does not work under Mac". Thanks for the
helpful assert message, no thanks for making your construct have random
platform-specific differences for no reason (it's not like menu item IDs
directly correspond to a part of Cocoa's menu API like they do on
Win32).
Incrementing the reference count here isn't necessary, as they construct with a count of 1. Incrementing again results in the attributes not being freed.
This technically also fixes a memory leak in WatchView.cpp, because the table setting was done such that the grid wouldn't take ownership of the table, which means said table wouldn't be deleted in the grid's destructor.
It's only function is in this pane. Leaving it on the main application toolbar not only looks gross, but subverts what a user might think it applies to.
The PowerPC CPU has bits in MSR (DR and IR) which control whether
addresses are translated. We should respect these instead of mixing
physical addresses and translated addresses into the same address space.
This is mostly mass-renaming calls to memory accesses APIs from places
which expect address translation to use a different version from those
which do not expect address translation.
This does very little on its own, but it's the first step to a correct BAT
implementation.
There are a couple things in this PR.
Fixes a bug where if we hit an invalid instruction we would infinite loop.
Fixes an issue where on AArch64 it would show invalid instructions for all NEON instructions.
This was due to asimd and crc being optional extensions and LLVM not enabling them by default.
So we have to specify a CPU which has the feature. LLVM 3.6 will let us select by features instead of CPUs, but we don't have a release of that quite
yet.
If we are on an architecture that has a known instruction size, we will continue onward after hitting the invalid instruction. If we don't have a
known instruction size like on x86, we will instead just dump the rest of the block.
Since the menus aren't actually assigned a parent, they would not be freed by wx. Plus, these should have initially been constructed on the stack in the first place.
Technically any time someone right-clicked the game list they would be leaking memory.
This will work for all of our platforms, x86, ARMv7, and AArch64.
Main issue with this is that LLVM's cmake files aren't correctly finding the LLVM install.
Not sure if this is Ubuntu's issue or not, it may just work on other operating systems.
We could potentially improve this, you can pass in a specific CPU in to the LLVM disassembler. This would probably affect latency times that are
reported by LLVM's disassembly? This needs to be further investigated later.
This code was an absolute mess. It had allocated an arbitrarily large string buffer to hold instructions that were disassembled.
Strip out all of the nasty raw C string manipulation and replaces it with ostringstream usage.
Fixes an issue where if you didn't have a JIT recompiler running then Dolphin would instantly crash if you tried comparing PPC to x86 code.
Changed the disassembly of the host side code from being inline to the function to instead being in a class, this will be required when I add support
for ARMv7 and AArch64 to this window.
Previously it did the opposite of what it was supposed to; when checked, it'd
turn block linking on, and when unchecked, it'd turn it off.
Also update JITIL's block linking disabling in debug mode to match the behavior
of the regular JIT.
These ID values would clash with the window parent IDs of all the actual debugger panes (they are in the 350 range as well).
For example, attempting to show and then close the memory window would cause an assertion, because it would attempt to destroy the text control for searching through memory, rather than destroying the actual parent window it's attached to.
These IDs are only used locally, so their value doesn't matter.
