[lldb] Print children-count warning for dwim-print and expr (#149088)
When dumping variables, LLDB will print a one-time warning about
truncating children (when the children count exceeds the default
`target.max-children-count`). But we only do this for `frame variable`.
So if we use `dwim-print` or `expression`, the output gets truncated but
we don't print a warning. But because we store the fact that we
truncated some output on the `CommandInterpreter`, we fire the warning
next time we use `frame variable`. E.g.,:
```
(lldb) p arr
(int[1000]) {
[0] = -5
[1] = 0
[2] = 0
<-- snipped -->
[253] = 0
[254] = 0
[255] = 0
...
}
(lldb) v someLocal
(int) someLocal = 10
*** Some of the displayed variables have more members than the debugger
will show by default. To show all of them, you can either use the
--show-all-children option to frame variable or raise the limit by
changing the target.max-children-count setting.
```
This patch prints the warning for `dwim-print` and `expression`.
I only added a test for the `target.max-children-count` for now because
it seems the `target.max-children-depth` warning is broken (I can't get
it to fire).
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
