Or rather, the test was not running as the test executable failed to compile. The problem is that Clang was emitting this warning: warning: argument unused during compilation: '-fdiagnostics-color=never' [-Wunused-command-line-argument] This warning is emitted when compiling the assembler file generated by the DWARF assembler. Most DWARF assembler tests generate the assembler file into a file with the '.S' extension. However, this particular test uses a '.s' extension. Now a .S file will be passed through the preprocessor, while a .s will be sent straight to the assembler. My guess is that Clang doesn't support the -fdiagnostics-color=never option for the assembler, but does for the preprocessor. That's a little annoying, but easily worked around. We don't care if our assembler file is passed through the preprocessor, so, in this commit, I just change the file extension from .s to .S, and the problem is fixed. Currently, the unavailable-dwarf-piece.exp script names the assembler file using standard_output_file, in this commit I've switched to make use of standard_testfile, as that seems to be the more common way of doing this sort of thing. With these changes the test now passes with Clang 9.0.1 and 15.0.2, and also still passes with gcc. --- gdb/testsuite/gdb.trace/unavailable-dwarf-piece.exp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gdb/testsuite/gdb.trace/unavailable-dwarf-piece.exp b/gdb/testsuite/gdb.trace/unavailable-dwarf-piece.exp index f80f8005fcf..13c6f38737c 100644 --- a/gdb/testsuite/gdb.trace/unavailable-dwarf-piece.exp +++ b/gdb/testsuite/gdb.trace/unavailable-dwarf-piece.exp @@ -20,9 +20,9 @@ if {![dwarf2_support]} { return 0 } -standard_testfile .c +standard_testfile .c -dbg.S -set asm_file [standard_output_file "${testfile}-dbg.s"] +set asm_file $srcfile2 set opts {} if { [gdb_compile ${srcdir}/${subdir}/${srcfile} ${binfile}1.o \ -- 2.25.4
