These # functions are emitted in each source file that include the header, # non-inlined when -O0 is used, and coalesced into a single copy by the # static linker. The static linker also tries to remove all of the debug # information except one copy when it coalesces these. If that debug # information defines a type that is later used by gdb, that results in # <incomplete type> errors. # This test file specifically tests for when the linker emits the debug # information for the class AFTER the debug information for the executable. # The debugger is supposed to handle this correctly, and only certain # linkers reorder things in this way while they're emitting the coalesced # debug info stuff. if $tracelevel then { strace $tracelevel } # # test running programs # set prms_id 0 set bug_id 0 set testfile "coalesced2" set srcfile1 "${testfile}a.cc" set objfile1 "${testfile}a.o" set srcfile2 "${testfile}b.cc" set objfile2 "${testfile}b.o" set binfile "${objdir}/${subdir}/${testfile}" set additional_flags "additional_flags=-gstabs+ -feliminate-unused-debug-symbols" if { [gdb_compile "$srcdir/$subdir/$srcfile1" "$objdir/$subdir/$objfile1" object {debug c++}] != "" } { gdb_suppress_entire_file "Testcase compile failed, so all tests in this file will automatically fail." } if { [gdb_compile "$srcdir/$subdir/$srcfile2" "$objdir/$subdir/$objfile2" object {debug c++}] != "" } { gdb_suppress_entire_file "Testcase compile failed, so all tests in this file will automatically fail." } if { [gdb_compile "$objdir/$subdir/$objfile1 $objdir/$subdir/$objfile2" "${binfile}" executable {debug c++}] != "" } { gdb_suppress_entire_file "Testcase compile failed, so all tests in this file will automatically fail." } if [get_compiler_info ${binfile} "c++"] { return -1 } # Start with a fresh gdb gdb_exit gdb_start gdb_reinitialize_dir $srcdir/$subdir gdb_file_cmd "${binfile}" send_gdb "set width 0\n" gdb_expect -re "$gdb_prompt $" set srcfile $srcfile1 gdb_test "break $srcfile:[gdb_get_line_number "good place to stop in coalesced2a"]" "Breakpoint 1 at $hex: file.*, line.*\\."
