remove the DisablePatternForFastISel predicate, which is a check
that predated -fast-isel which attempted to speed up the dag pattern
matchers at -O0.  Since fast-isel is around, this is basically
obsolete and removing it shrinks the generated dag isels.

14 years agoWhen complicated expressions are broken down into subexpressions

When complicated expressions are broken down into subexpressions
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.
