breakpoint on a non-executable line

breakpoint on a non-executable line

[Jafa]

Hi all,

I am seeing a problem/feature? of gdb (June top of trunk) where if you issue
a command to set a breakpoint on a non-executable line it will return the
line specified, regardless of where it actually set.

For example:

(gdb) b  /ubicom/toolchain/src/ld/ldmain.c:1
Breakpoint 2 at 0x41b800: file /ubicom/toolchain/src/ld/ldmain.c, line 1.

(It actually put the breakpoint on line 167).

Is this the desired behavior? I would have expected it to return success -
line 167.

Nick

Do you know if this is a change?

Hi Daniel,

> Do you know if this is a change?

yes, we moved to the top of trunk in December last year and started to see
the problem. The previous version was about 2001 and worked as I would
expect.

I can check the exact dates if you like, or I don't mind working through
it... I just wanted to make sure it wasn't a deliberate change.

Thanks

Nick
