This is the approach suggested upstream, Note: You can also use command alias, discussed in Command Aliases and Help, to make commonly used command-line expressions easy to remember, as well as able to be entered with only a few keystrokes.
specify ââshlib
This means that basic support and upstream to LLVM. plugin. For example: Using these features of LLDB offers much the same âshorthandâ feel and brevity as when using GDB. It doesnât do everything that the GDB break command does (for instance, it doesnât handle an expression like break foo.c::bar). youâll have to indicate these are not option markers by putting âââ after the For example: This command parsing design helps make LLDB command syntax regular and uniform across all commands. For a complete explanation of command alias construction, limitations, and syntax, use the LLDB help system. by Darwin, Linux, NetBSD and (unofficially) OpenBSD. into the FPU they are loaded into internal registers 7, 6, 5… but from the added, they donât pick up these modifications, and the options only exist in of actual data register contents. All the features of the debugger are available as classes in the Python interpreter. To set a breakpoint on all C++ methods named foo, enter: To set a breakpoint on Objective-C selectors named alignLeftEdges:, enter: You can limit any breakpoints to a specific executable image by using the --shlib
before you send us your feedback. as a part of it. â(global==5)â is true: To launch a program in lldb we use the âprocess launchâ command or one of its built in aliases: You can also attach to a process by process ID or process name. focus on covering the differences between the two BSD platforms
When a new process is created by the CreateProcess function, handles of the new process and its primary thread are returned. LLDB reads the file ~/.lldbinit at startup. For example, the following two command-line expressions demonstrate the same command: Similarly, you can combine both shortest-unique-string matching with the abbreviated option format to reduce keystrokes. This is generally done by combining the abridged value with inspection In addition to breakpoints, you can use help watchpoint to see all the commands For advanced users, LLDB has a built-in Python interpreter accessible by using the script command. That makes the command syntax more regular, but it also means you In GDB, to set a breakpoint you might enter the following to break at line 12 of foo.c: And you might enter the following to break at the function foo: More complex break expressions are possible in GDB. support. little disconcerting to gdb users when always have an (lldb) prompt. If you always want to run in After launching, we can continue until we hit our breakpoint. upstream. form is used by the FSAVE/FRSTOR instructions. One example is (gdb) break foo.c::foo , which means âset the breakpoint in the function foo in the file foo.c.â But at some point the GDB syntax becomes convoluted and limits GDB functionality, especially in C++, where there may be no reliable way to specify the function you want to break on. Eventually, as the new plugin becomes par with the legacy one For example, here is a partial listing of the command options for the breakpoint set command, listing the canonical form in parentheses: Options can be placed in any order on the command line following the command. With reasonably small changes, we were able to support controlling the process (resume, stop, single step), handle basic event signals, read and write general-purpose and debug registers, read and write traced process’ address space, insert and handle software assisted breakpoints.
