uabelho added a comment. Hi,
I noticed that on one of our downstream (not public) buildbots the clang/test/Driver/femit-dwarf-unwind.s test seems to fail rather randomly. So if I run clang -target x86_64-apple-macos11.0 -c ../clang/test/Driver/femit-dwarf-unwind.s -o foo.o llvm-objdump --macho --dwarf=frames foo.o a couple of times I sometimes get .debug_frame contents: .eh_frame contents: and sometimes I get .debug_frame contents: .eh_frame contents: 00000000 00000014 00000000 CIE Format: DWARF32 Version: 1 Augmentation: "zR" Code alignment factor: 1 Data alignment factor: -8 Return address column: 16 Augmentation data: 10 DW_CFA_def_cfa: reg7 +8 DW_CFA_offset: reg16 -8 DW_CFA_nop: DW_CFA_nop: CFA=reg7+8: reg16=[CFA-8] 00000018 0000001c 0000001c FDE cie=00000000 pc=00000000...00000001 Format: DWARF32 DW_CFA_def_cfa_offset: +8 DW_CFA_nop: DW_CFA_nop: DW_CFA_nop: DW_CFA_nop: DW_CFA_nop: 0x0: CFA=reg7+8: reg16=[CFA-8] On another machine I don't seem to get that problem though, even if I compile in the same way so I really don't know what the difference is or why it is happening at all. Any ideas? Anything anyone else is seeing?
