Hi,
Thanks to pravindra's patch [1], Gandiva loop vectorization is okay now.
Will Gandiva detects CPU feature at runtime? My test CPU supports sse to
avx2, but I only
see "target-features"="+fxsr,+mmx,+sse,+sse2,+x87" in IR, and final code
doesn't leverage
registers longer than 128.
Can you please give some details about the hardware/OS-version you are
running this on ? Also, are you building the binaries and running them on
the same host ?
I'm building and running on same host.
