There is still the openmp patch that needs to be backported (I'll file a bug in a minute), and LLDB keeps failing some tests (not a regression) but it's all ok besides that. -- Best regards, Michał Górny signature.asc Description: This is a digitally signed message part ___ lldb-dev mailing list lldb-dev@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
[lldb-dev] Disassembling issue
Hi everyone, I'm trying to have lldb being able to debug my architecture. It does it well after loading my elf. But then I run it, stop it in middle, try to disassemble and at that point it seems that I lost some information about my architecture. lldb tries to disassemble it for x86, which in not possible with my toolchain. Here is a log of what I am doing: (lldb) file test Current executable set to 'test' (dpu). (lldb) dis -s 0x8000 test`__bootstrap: test[0x8000] <+0>: jnzid, 0x8020 test[0x8008] <+8>: move r0, 0xff test[0x8010] <+16>: release r0, 0x0, nz, 0x8018 test[0x8018] <+24>: subr0, r0, 0x1, pl, 0x8010 (lldb) r Process 21312 launched: '/home/rjodin/work/dpu_tools/llvm/lldb/test/test' (dpu) Process 21312 stopped * thread #1, name = 'DPUthread0', stop reason = Thread stopped frame #0: 0x8090 (lldb) dis -s 0x8000 error: Unable to find Disassembler plug-in for the 'x86_64' architecture.

Re: [lldb-dev] Disassembling issue
The error is coming from source/Commands/CommandObjectDisassemble.cpp . It’s not able to create the disassembler for your architecture. The call to Disassembler::FindPlugin fails. My guess is something in the call to MCDisasmInstance::Create in source/Plugins/Disassembler/llvm/DisassemblerLLVMC.cpp is failing. Step through that and make sure everything there is working.

As with 8.0.1 rc1, I had to disable compiler-rt for this test run, as most of the sanitizers are totally broken. This is tracked in PR40761.

Re: [lldb-dev] Disassembling issue
Hi Ted, Thank you for the answer. I'm not sure I understand you well. It seems to me that my program call "Disassembler::FindPlugin" with the "m_options.arch" set to "x86_64". But my toolchain does not contain a LLVM supporting x86_64, so it feels normal to me that it is not able to create this disassembler. What is weird is that the first time I'm executing it, it managed to do so. I also have kind of the same issue with breakpoint. It's like if I'm missing the debug information after I do the "run" command: (lldb) file test Current executable set to 'test' (dpu). (lldb) b main Breakpoint 1: where = test`main + 24 at test.c:8, address = 0x8078 (lldb) r Process 21312 launched: '/home/rjodin/work/dpu_tools/llvm/lldb/test/test' (dpu) Process 21312 stopped * thread #1, name = 'DPUthread0', stop reason = Thread finished frame #0: 0x80c0 (lldb) b main Breakpoint 2: no locations (pending). WARNING: Unable to resolve breakpoint to any actual locations. When I'm doing the disassembly, I can manage to disassemble if I add the option with my architecture to the command line, but as you can see below, I also do not have the debug information that I had at the first disassembly: (lldb) file test Current executable set to 'test' (dpu). (lldb) dis -s 0x8000 test`__bootstrap: test[0x8000] <+0>: jnzid, 0x8020 test[0x8008] <+8>: move r0, 0xff test[0x8010] <+16>: release r0, 0x0, nz, 0x8018 test[0x8018] <+24>: subr0, r0, 0x1, pl, 0x8010 (lldb) r Process 21312 launched: '/home/rjodin/work/dpu_tools/llvm/lldb/test/test' (dpu) Process 21312 stopped * thread #1, name = 'DPUthread0', stop reason = Thread finished frame #0: 0x80a0 (lldb) dis -s 0x8000 error: Unable to find Disassembler plug-in for the 'x86_64' architecture.
