Hi,
For this case:
1. last_combine1 the general pattern(plus (mult a b) c) can’t be combined.
2. last_bombine2 vec_duplicated is expanded to broadcast which can’t be
handled by last_combine.
For RVV, I think last_combine2 has no chance to combine anything because of
fully expansion. Do I u
Ah, thanks! I took a quick look today and I'll look more today.
I should have a patch ready in about two weeks, but I'm gonna attach
some notes and a link to the git repository I'm working on, in case
anyone on the mailing list wants to take a look at it and provide
feedback and/or request things

I think Demin is working on it. And Robin is reviewer of this stuff.

Couldn’t the generated files be committed to the tree, so that flex is not
needed (unless one modifies the source). This is what is done

The standard says it's unspecified whether those types are the same,
so portable code should not assume they are/aren't the same. I don't
know for sure, but I assume somebody thought that making them
different was helpful to avoid non-portable code.

-
#include
using int_set1 = std::set>;
using int_set2 = std::set;
static_assert(std::is_same());

the two iterators are equal when not using _GLIBCXX_DEBUG but become
different when using the define?
Hi Julian,
I hope you have Ulrich's document about TLS, if not please google it:
"ELF Handling for Thread-Local Storage - Ulrich Drepper"
In ARC, I used unspec constructions to emit TLS addresses. If you
wanna simplify it, in the legitimzie_tls_address you can only
implement the most general case
Sure - we actually already emit json in optinfo-emit-json.cc, and there
are implementations of json and pretty-printing/dumping it out also. I got
a hacky version of our current raw dump working with json objects, but
