[M3commit] [modula3/cm3] 6e1d2c: Several fixes for Mac OS X 10.10.4 Yosemite. More ...

[Jay K]

Clarification:
-gstabs/-gstabs+ didn't crash or error.They error in the assembler now.

The data was likely not consumed by anything.
m3gdb declines to build for Mac OSX.I suspect just because it is old but I haven't followed up.

So I removed -gstabs and -gstabs+, and left -g.But that crashes.And probably always did.

That should probably be fixed, but -g1 for now is my suggestion.

Once I fix "the driver matter", I'll go back to the C backend anyway, wherefairly rich debugging information is builtin. :)But not knowledge of texts and open arrays.

It probably used to work only with -gstabs.

We should perhaps fix -g though.It is a null dereference generating dwarf output.

A valid workflow in Xcode is to debug by name, you canenter the name of a process that isn't running yet, and then run cm3cg.

i.e. if you don't yet know how to use lldb on the command line andhaven't gone through the trouble of building/installing gdb.If gdb even still works.

This one rings a bell, but I can’t put my finger on it.Perhaps check the m3cc commit logs?
