Hi all,
I'm looking at a case where some RTL passes create an RTL expression of the
form:
(subreg:QI (and:SI (reg:SI x1)
(const_int 31)) 0)
which I'd like to simplify to:
(and:QI (subreg:QI (reg:SI x1) 0)
(const_int 31))
Because (const_int 31) masks out the upper bits after

Hi
Is there something special needed to commit via git? I got an odd error pushing
some minor RTEMS patches and wondered what the proper procedure was.
I am using the same commands and process I use with newlib so was wondering.
The website has svn instructions so maybe I am just confused after

Perhaps this question is appropriate for the gcc mail list.
Converting a float/double to unsigned int is undefined if the result
would be negative when converted to a signed int.
x86-64 and arm treat this condition differently---x86-64 returns a value
whose bit pattern is the same as the bit
