Also check for the most common event type (sample) first instead of
leaving it as the fallback. This avoids a lot of string comparisons
while parsing profiles.

This reverts commit 012fc3f92317b1f1c96a9829755593463d9630e1.

28b1e66b51ec7b4552a12ac5ee37ecd6b96d4541 made that
the m_all_editor_wrappers vector is cleared everytime a project path
is changed (the m_project if check is just for the app launch --
the vector is empty there anyway), making the code never execute.
|
|
Previously when user wanted to save an uncreated file, the program
would just quietly ignore the save request, without giving any message.
This can be seen when creating a new editor in split view mode.
|
|
Not adding it to the toolbar, because it has the same icon as
a typical 'Save' action.
|
|
The user can now start typing text instead of creating a file first.
This also enables drag-and-dropping a file as soon as the application
starts.
|
|
Making userspace provide a global string ID was silly, and made the API
extremely difficult to use correctly in a global profiling context.
Instead, simply make the kernel do the string ID allocation for us.
This also allows us to convert the string storage to a Vector in the
kernel (and an array in the JSON profile data.)
|
|
The first perf_event argument to a PERF_EVENT_SIGNPOST is now
interpreted as a string ID (in the profile strings set.)
This allows us to generate signposts with custom strings. :^)
|
|
Signposts generated by perf_event(PERF_EVENT_SIGNPOST) now show up in
profile timelines, and if you hover them you get a tooltip with the two
arguments passed with the event.
|
|
Prior this change, the action opened a File Picker
in user home directory.
Changing the startup path to a project path might make correcting
the path or switching between different projects a bit faster,
as you don't have to go through the subdirectories all over again.
It's also the path that's showed in the project tree view.
|
|
Previously the view would've cut off at the last instruction that was
hit in the profile, which is not the right behaviour for functions.
|
|
Profiler uses the TreeView in a tabular fashion, and so should set the
selection behavior appropriately.
|
|
This allows LibC to fall back to sys$clock_gettime() until we can
add support for the kernel time page to UserspaceEmulator.
|
|
Now that LibC uses clock_gettime() to implement gettimeofday(), we can
get rid of this entire syscall. :^)
|
|
Them being in the global namespace doesn't have a lot of fans, it seems.
|
|
This can happen if the symbol is part of a switch-case, and not
a function, which would previously have made the disassembly view
appear empty.
Now we disassemble the containing function, starting at the given label
and continuing up until the last captured instruction.
|

|
Since we now have this helper template, we can make our code cleaner.
|

... segment
This happens with binaries build with Clang or with a custom linker
script. If this is the case, offsets should be calculated not from the
base address of `.text`, but from the first section loaded for the
library.
This commit moves all UserspaceEmulator symbolication into a common
helper function and fixes a FIXME.
|
|
Changes `load_library_from_adress` to `load_library_from_address`.
|
|
After this change, the parser is completely separated from preprocessor
concepts.
|
|
When the preprocessor encounters an #include statement it now adds
the preprocessor definitions that exist in the included header to its
own set of definitions.
We previously only aggregated the definitions from headers after
processing the source, which was less correct. (For example, there
could be an #ifdef that depends on a definition from another header).
|
|
We now call Preprocessor::process_and_lex() and pass the result to the
parser.
Doing the lexing in the preprocessor will allow us to maintain the
original position information of tokens after substituting definitions.
|
|
The previous name did not describe what the function checked, and was
easy to confuse with ModelIndex::is_valid.
|
|
Most of the models were just calling did_update anyway, which is
pointless since it can be unified to the base Model class. Instead, code
calling update() will now call invalidate(), which functions identically
and is more obvious in what it does.
Additionally, a default implementation is provided, which removes the
need to add empty implementations of update() for each model subclass.

With this, we can now have some amount of source-level profiling
information :^)
|
|
This is required to avoid copying the image where otherwise a reference
would be enough.
|
|
`ue --profile --profile-file ~/some-file.profile id` can now generate a
full profile (instruction-by-instruction, if needed), at the cost of not
being able to see past the syscall boundary (a.la. callgrind).
This makes it significantly easier to profile seemingly fast userspace
things, like Loader.so :^)
|
|
This implements bits and pieces to get the debugging functionality to
build. No testing has been done to check whether it actually works
because GCC doesn't currently work.
|
|
Previously files in the open files view would stay open from the
previous project, and files in the new project with the same name as
files in the old one would be inaccessible, with the old ones showing
up instead. Now all files and open editors are closed before a new
project is opened.
Fixes #9103

This adds more possible extensions for highlighting C/C++ files
and JavaScript module files.
|
|
|
|
.html files were recognised before -- the name was shown on
the statusbar, but it didn't actually enable the syntax highlighting.
This also sneaks a highlighting for JSON using JS highlighting.
It isn't technically correct, but so does TextEditor. :^)
|
|
|
|
This allows us to show a GML Preview in realtime via
HackStudio::GMLPreviewWidget! :^)

The splitters all felt a little bit too small and hard-to-grab.
This patch puts a little more fat on them.
|
|
This enables further work on implementing KASLR by adding relocation
support to the pre-kernel and updating the kernel to be less dependent
on specific virtual memory layouts.
|
|
Splitter does weird things when you resize and then remove children.
This works around the limitation by forcing at least one of the editors
to fill the space. It's janky, but at least doesn't result in the last
editor not filling the window.

This implements almost all instructions related to the FPU, including
all MMX instructions as well.
A lot of these were copied and adjusted from the SoftCPU implementation.
The next big milestone would be QNan detection and ShadowValue handling.

These are placeholders for now
