Hi.
This is the full patch for roundeven folding. The patch bootstraps and
passes regression tests.

Hi,
This is a full patch for the roundeven variants along with
documentation and additional testcases. The following code also
conforms to GNU's coding standards.
Thanks,

I don't think they should be documented with the __builtin_* that are
always expanded inline. They should be do

wouldn't checking for *signalling* NaNs mean usi
Hi.
Here is a clean patch that does not fold roundeven resulting for
integer type and the conditions for folding functions
round/ceil/floor/roundeven and trunc only checks for signaling NaN.
This patch also conforms to GNU's coding style and standards. The fact
that it should be CASE_MATHFN_FLOATN

Checking flag_errno_math here does not make sense. roundeven never sets
errno (at least, TS 18661-1 makes it implementation-defined whether
Hi Joseph,
can you please have look at this patch from Tejas, whether it is perhaps
ready to be committed to trunk or what things still need to be
addressed?
Thanks a lot,

Hi.
This patch includes implementation of new function roundeven along
with two utility functions. The patch bootstraps on x86_64-linux-gnu
and passes regression tests.
Thanks,
