During development of the patch I just posted for double-word clz, I
went through all the back ends and audited their use of the bit-scan
named patterns and RTL. It appears to me that our current handling of
C[LT]Z_DEFINED_VALUE_AT_ZERO is much more complicated than it needs to
be, and also that

Good point, thanks.
I don't think that is enough though, because I don't think the BINFO

even after the PTR_PLUS merge and fix for PR28690. One of the cases I

Zadeck has the parloop branch patches, which I've been reviewing. I am
not sure how many other

However, I'm not sure I agree with the above assertion. Specifically,
for Java I think it is sometimes possible

Hi, trying to come up with a testcase we figured out what the problem could be.
When the optimizer is on and memcpy sees that it is copying a struct
with double words in it, it will assume that the struct starts on an 8
byte boundary and use double word loads and stores. This is a safe
assumption,

I think you need one to lex

Hi,
my questions is, why not use the element construction algorithm? The Thomson
Algorithm creates an epsilon-NFA which needs quite a lot of memory. The
element construction creates an NFA directly and therefor has fewer states.
Well, this is only interesting in the scanner
