Summary: Constant folding for 'frem' is flaky
Product: libraries
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P2
Component: Core LLVM classes
AssignedTo: unassignedbugs at nondot.org

CC: llvmbugs at cs.uiuc.edu
Constant folding for 'frem' seems flaky for certain values. For example, "frem
float 0.1, 1.0" returns -0.9 when constant folded:
define float @test1() {
entry:
%y = frem float 0x3FB99999A0000000, 1.0
ret float %y
}
@x = global float 0x3FB99999A0000000 ; float 0.1
define float @test2() {
%x = load float* @x
%y = frem float %x, 1.0
ret float %y
}
