URL: https://github.com/llvm/llvm-project/commit/723a1caa377b898ff3dc0897156f544feab99ac8 DIFF: https://github.com/llvm/llvm-project/commit/723a1caa377b898ff3dc0897156f544feab99ac8.diff LOG: Fix the crashlog.py script's use of the load_address property. This property is explicitly for use only in the interactive editor, and NOT in commands. It's use worked until we got more careful about not leaving lldb.target lying around in the script interpreter. I also added a quick sniff test for the save_crashlog command. <rdar://problem/60350620> Differential Revision: https://reviews.llvm.org/D80680 Added: lldb/test/API/macosx/save_crashlog/Makefile lldb/test/API/macosx/save_crashlog/TestSaveCrashlog.py lldb/test/API/macosx/save_crashlog/main.c Modified: lldb/examples/python/crashlog.py Removed: ################################################################################ diff --git a/lldb/examples/python/crashlog.py b/lldb/examples/python/crashlog.py index b7b62acc60ef..1c1602b0131e 100755 --- a/lldb/examples/python/crashlog.py +++ b/lldb/examples/python/crashlog.py @@ -791,11 +791,11 @@ def save_crashlog(debugger, command, exe_ctx, result, dict): block_range = block.range[frame.addr] if block_range: block_start_addr = block_range[0] - frame_offset = frame_pc - block_start_addr.load_addr + frame_offset = frame_pc - block_start_addr.GetLoadAddress(target) else: - frame_offset = frame_pc - frame.function.addr.load_addr + frame_offset = frame_pc - frame.function.addr.GetLoadAddress(target) elif frame.symbol: - frame_offset = frame_pc - frame.symbol.addr.load_addr + frame_offset = frame_pc - frame.symbol.addr.GetLoadAddress(target) out_file.write( '%-3u %-32s 0x%16.16x %s' % (frame_idx, frame.module.file.basename, frame_pc, frame.name)) diff --git a/lldb/test/API/macosx/save_crashlog/Makefile b/lldb/test/API/macosx/save_crashlog/Makefile new file mode 100644 index 000000000000..695335e068c0 --- /dev/null +++ b/lldb/test/API/macosx/save_crashlog/Makefile @@ -0,0 +1,4 @@ +C_SOURCES := main.c +CFLAGS_EXTRAS := -std=c99 + +include Makefile.rules diff --git a/lldb/test/API/macosx/save_crashlog/TestSaveCrashlog.py b/lldb/test/API/macosx/save_crashlog/TestSaveCrashlog.py new file mode 100644 index 000000000000..c86294490f61 --- /dev/null +++ b/lldb/test/API/macosx/save_crashlog/TestSaveCrashlog.py @@ -0,0 +1,68 @@ +""" +Test that the save_crashlog command functions +""" + + +import os +import lldb +import lldbsuite.test.lldbutil as lldbutil +from lldbsuite.test.lldbtest import * +from lldbsuite.test.decorators import * + + +class TestSaveCrashlog(TestBase): + + mydir = TestBase.compute_mydir(__file__) + + # If your test case doesn't stress debug info, the + # set this to true.
