Hello!
Attached patch fixes omission from "(int) rint ()" conversion to
__builtin_irint (). We can vectorize this function when out_mode is
SImode, no matter how the builtin is called. Throw in also
BUILT_IN_LLRINT, just for completion ...
2011-11-07 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.c (ix86_builtin_vectorized_function): Handle
BUILT_IN_IRINT, BUILT_IN_IRINTF, BUILT_IN_LLRINT and BUILT_IN_LLRINTF.
Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu
{,-m32}, committed to mainline SVN.
BTW: It would be nice if convert.c also converted "(int) lrint ()" to
__builtin_lrint (), but this is somehow beyond my middle-end skills...
Uros.
