  "message": "[gdb/testsuite] Avoid using .eh_frame in gdb.base/unwind-on-each-insn.exp\n\nOne purpose of the gdb.base/unwind-on-each-insn.exp test-case is to test the\narchitecture-specific unwinders on foo, so unwind-on-each-insn-foo.c is\ncompiled with nodebug, to prevent the dwarf unwinders from taking effect.\n\nFor for instance gcc x86_64 though, -fasynchronous-unwind-tables is enabled by\ndefault, generating an .eh_frame section contribution which might enable the\ndwarf unwinders and bypass the architecture-specific unwinders.\n\nCurrently, that happens to be not the case due to the current implementation\nof epilogue_unwind_valid, which assumes that in absence of debug info proving\nthat the compiler is gcc \u003e\u003d 4.5.0, the .eh_frame contribution is invalid.\n\nThat may change though, see PR30028, in which case\ngdb.base/unwind-on-each-insn.exp stops being a regression test for commit\n49d7cd733a7 (\"Change calculation of frame_id by amd64 epilogue unwinder\").\n\nFix this by making sure that we don\u0027t use .eh_frame info regardless of\nepilogue_unwind_valid, simply by not generating it using\n-fno-asynchronous-unwind-tables.\n\nTested on x86_64-linux, target boards unix/{-m64,-m32}, using compilers\ngcc 7.5.0 and clang 13.0.1.\n",
