<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-lldb Author: Duncan McBain (DuncanMcBain) <details> <summary>Changes</summary> Several languages support some sort of "breakpoint" function, which adds ISA-specific instructions to generate an interrupt at runtime. However, on some platforms, these instructions don't increment the program counter. When LLDB sets these instructions it isn't a problem, as we remove them before continuing, then re-add them after stepping over the location. However, for breakpoint sequences that are part of the inferior process, this doesn't happen - and so users might be left unable to continue past the breakpoint without manually interfering with the program counter. This patch adds logic to LLDB to intercept SIGTRAPs, inspect the bytes of the inferior at the program counter, and if the instruction looks like a BRK or BKPT or similar, increment the pc by the size of the instruction we found. This unifies platform behaviour (e.g. on x86_64, LLDB debug sessions already look like this) and improves UX (in my opinion, but I think it beats messing with stuff every break). Some ISAs (like AArch64) require slightly different handling, as while there are multiple possible instructions, we should be careful only to find the ones likely to have been emitted by a compiler backend, and not those inserted from (for example) the UB sanitizer, or any others. There is an existing builtin-debugtrap test which was under the macos folder before. I've now moved that to "functionalities", made it pure C only, and updated it a little bit so that it works regardless of platform. What I've not done is change the existing code in debugserver which was added by @<!-- -->jasonmolenda about five years ago (https://reviews.llvm.org/D91238, 92b036d). It might not be required any more after this change. Reading the history there, it seems like it was agreed that this behaviour (skipping over unknown bps) was the desired end goal. I'd also like to tag @<!-- -->jimingham as this patch messes with the handling of breakpoints. --- Patch is 22.21 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/174348.diff 13 Files Affected: - (modified) lldb/include/lldb/Core/Architecture.h (+11) - (modified) lldb/include/lldb/Target/Platform.h (+11) - (modified) lldb/source/Plugins/Architecture/AArch64/ArchitectureAArch64.cpp (+17) - (modified) lldb/source/Plugins/Architecture/AArch64/ArchitectureAArch64.h (+3) - (modified) lldb/source/Plugins/Architecture/Arm/ArchitectureArm.cpp (+30) - (modified) lldb/source/Plugins/Architecture/Arm/ArchitectureArm.h (+4) - (modified) lldb/source/Plugins/Architecture/Mips/ArchitectureMips.cpp (+11) - (modified) lldb/source/Plugins/Architecture/Mips/ArchitectureMips.h (+4) - (modified) lldb/source/Target/Platform.cpp (+64-62) - (modified) lldb/source/Target/StopInfo.cpp (+34) - (renamed) lldb/test/API/functionalities/builtin-debugtrap/Makefile (+1-1) - (renamed) lldb/test/API/functionalities/builtin-debugtrap/TestBuiltinDebugTrap.py (+13-10) - (renamed) lldb/test/API/functionalities/builtin-debugtrap/main.c () ``````````diff diff --git a/lldb/include/lldb/Core/Architecture.h b/lldb/include/lldb/Core/Architecture.h index ed64a895717a1..38b307476b3e7 100644 --- a/lldb/include/lldb/Core/Architecture.h +++ b/lldb/include/lldb/Core/Architecture.h @@ -138,6 +138,17 @@ class Architecture : public PluginInterface { std::shared_ptr<const UnwindPlan> current_unwindplan) { return lldb::UnwindPlanSP(); } + + /// Returns whether a given byte sequence is a valid breakpoint for the + /// architecture.
