Manuel López-Ibáñez <manu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu.org --- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Christophe from comment #0) > I must also add that the problem is the same for -00 and -02. I can imagine that --help= only reports the machine-independent defaults encoded in opts.c, but machine-specific are not specified there. It would be nice if there was an equivalent of *.opt files (or even the *.opt files syntax was extended for this purpose). > The question is : how can I know which options are effectively enabled or > not ? Can I easily find the answer in source code ? By using gdb and following the code as it executes? I would put a breakpoint in opts.c and continue from there.
