--- Comment #44 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- (In reply to David Edelsohn from comment #43) > I upgraded GDB on gcc119 with GDB 7.9.1 + IBM patches. It may work a little > better. FWI, the gdb on /opt/freeware/bin/gdb is even worse now. I can't put any breakpoints anymore (at least not on tree-ssa-structalias.c). In the meantime I am using ~dje/bin/gdb-7.6 which I can at least breakpoint and single step the assembly.
