Fixes https://bugs.llvm.org/show_bug.cgi?id=48882. If the input file does not exist (or has a reading error), the following code will crash if there are two or more input addresses. ``` auto ResOrErr = Symbolizer.symbolizeInlinedCode( ModuleName, {Offset, object::SectionedAddress::UndefSection}); Printer << (error(ResOrErr) ? DILineInfo() : ResOrErr.get().getFrame(0)); ``` For the first address, `symbolizeInlinedCode` returns an error. For the second address, `symbolizeInlinedCode` returns an empty result (not an error) and `.getFrame(0)` will crash. Differential revision: https://reviews.llvm.org/D95609

This test checks that when inlined frames are not shown (--no-inlines) and the output
|
|
style is set to GNU (--output-style=GNU) the name of an inlined function is not
|
|
replaced with the name of the top caller function. At the same time, the current
|
|
behavior of llvm-symbolizer is preserved with --output-style=LLVM or when
|
|
the option is not specified.
