The code with an intermediate register is perfectly fine, but LRA
apparently cannot handle the resulting code, or perhaps something else
is wrong. In either case, making an extra temporary will not likely
help here, so let's just skip it.

The predicates for bswap2_{load,store} are now
indexed_or_indirect_operand,
and bswap2 uses rs6000_force_indexed_or_indirect_mem to make sure the
address is appropriate for that predicate.

Hi,
the attached patch increases the move costs for moves involving the CC
register. This saves us some instructions in SPEC CPU2006.

If the nearest common dominator appears in the loop while all uses are
out of loops, this will result in suboptimal xor placement.
In this case you want to split edges out of the loop.
In general this is what the LCM framework will do for you if
In order to properly fix PR87762, we need to distinguish between
instructions which support relative addressing and instructions which
don't. We could check whether the existing "type" attribute is equal to
"larl", but there are notable exceptions (lrl, for example), and
changing them makes

Hi,
this patch fixes the miscompare I introduced to spec2006 GCC benchmark
when build with LTO.
The problem is that fld_incomplete_type_of builds new pointer type to
incomplete type rather than complete but it ends up giving wrong type
canonical.
This patch also improves TBAA with early opts
Hi.
There's a sparc fix that I've just installed in libsanitizer upstream
repository. I'm going to install it into GCC's trunk.
