X-Git-Tag: 0.4.23~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=106dacc2620126dedb99d2b981ba2e5a7d4591f9;p=platform%2Fupstream%2Forc.git

When loading a const in a register, always make it cover the full
register so that it containts enough values to be used in x2 and
x4 instructions.
