Subject: [RISCV] Move some RISCVLoadFPImm out of line. NFC
X-Git-Tag: upstream/17.0.6~15286
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d704c7a6b3656e0a049f3c547ad5e2cbe4539c60;p=platform%2Fupstream%2Fllvm.git

[RISCV] Move some RISCVLoadFPImm out of line. NFC

This moves the LoadFPImmArr array to the cpp file. Being in the header
meant it was duplicated in every translation unit that includes the
header.

Move the 2 functions that use the array out of line.
