Subject: [Sema] Enable -Wimplicit-float-conversion for integral to floating point precision... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=281e7e161d059513eb14c73e4acc5c650a2d2fbc;p=clang

[Sema] Enable -Wimplicit-float-conversion for integral to floating point precision loss

Fix one test case for it to be system-independent.
