From e77b0004dd114d6ddf3bb92b521b2854341f3f85 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 5 Feb 2021 17:47:07 +0100 Subject: [PATCH] [gdb/symtab] Handle DW_TAG_type_unit in process_psymtab_comp_unit When running test-case gdb.cp/cpexprs-debug-types.exp with target board unix/gdb:debug_flags=-gdwarf-5, I run into: ... (gdb) file cpexprs-debug-types^M Reading symbols from cpexprs-debug-types...^M ERROR: Couldn't load cpexprs-debug-types into GDB (eof). ERROR: Couldn't send delete breakpoints to GDB. ERROR: GDB process no longer exists GDB process exited with wait status 23054 exp9 0 0 CHILDKILLED SIGABRT SIGABRT ... We're running into this abort in process_psymtab_comp_unit: ... switch (reader.comp_unit_die->tag) { case DW_TAG_compile_unit: this_cu->unit_type = DW_UT_compile; break; case DW_TAG_partial_unit: this_cu->unit_type = DW_UT_partial; break; default: abort (); } ... because reader.comp_unit_die->tag == DW_TAG_type_unit. Fix this by adding a DW_TAG_type_unit case.
