33 | # savvy about gdb's workings and the meaning of the "{}" | |
34 | # construct. So the details maybe could be tweaked. But the | |
35 | # basic purpose should be maintained, which is (a) users should be | |
36 | # able to interact with these variables with some care (they have | |
37 | # to know how to interpret them according to their real type, | |
38 | # since gdb doesn't know the type), but (b) users should be able | |
39 | # to detect that gdb does not know the type, rather than just | |
40 | # being told they are ints or functions returning int like old | |
41 | # versions of gdb used to do. | |

46 | # Irix5, even though it is ELF, counts as "ecoff" because it | |
47 | # encapsulates ecoff debugging info in a .mdebug section. | |
