Hello,
Is there a gcc option to disable the generation of .cold functions? I
can't find anything explicit in the driver source/Makefile to create
.cold functions.
I am running into problems with an older version of gdb not handling
.cold functions correctly.
Thanks
Kit

You could try -fno-reorder-blocks-and-partition. I just found the
option in the documentation, so I don't know if it really works for this
specific case, sorry.
