Hi Michael,
This idiom also appears in newlib and in various versions of GDB and
associated codebases. I'm not sure how this maps to actual development
repos.
Well GDB shares a repo with the binutils, but newlib has its own repo.
All forms I found are one of the following source text snippets:
(m = 1; m != 0; m <<= 1)
(i = 1; i; i <<= 1)
If you grep for that, you may find more. Of course, it's only a bug if
the variable is signed.
I checked, but could not find any other places in the binutils sources where
this kind of expression appears. (With a signed variable that is).
I found one place in the GDB sources where bug appears to be real:
sim/common/cgen-scache,c: scache_option_handler(). So I will submit a bug
report about that.
I am not a newlib expert, so I have left those sources alone.
Cheers
Nick
