Please ignore my 1st try with the wrong email address for Richard Sandiford Greetings, I seek feedback on the attached patch, which enhances the .map file to show better address info on AIX XCOFF garbage collected symbols. --Douglas Rupp, AdaCore =============== The current .map file output with -nogc is something like this: .pr 0x100012b0 0x20 ./pack1.o 0x100012b0 .pack1__fooIP 0x100012c0 .pack1__bumIP .pr 0x100012d0 0x60 ./test1.o ---------- The current .map file output with -gc (the default) is something like this: .pr 0x100012b0 0x0 ./pack1.o 0x100012b0 .pack1__fooIP 0x100012c0 .pack1__bumIP .pr 0x100012b0 0x60 ./test1.o Note that .pack1__fooIP and .pack1__bumIP have been gc'd and the addresses make no sense. ------------ The output with the attached patch is something like this: .pr 0x100012b0 0x0 ./pack1.o 0x100012b0 -->gc 0x100012b0 .pack1__fooIP 0x100012c0 -->gc 0x100012b0 .pack1__bumIP .pr 0x100012b0 0x60 ./test1.o -------------- next part -------------- A non-text attachment was scrubbed...
