This is the entry block:
%"entry" = entry:
  %".2" = bitcast [6 x i8]* @"fstr" to i64*
  %".3" = alloca double
  store double 0x3ff0000000000000, double* %".3"
  %".5" = alloca double
  store double 0x4024000000000000, double* %".5"
  br label %"entry.cond"

This is the main function:
define i32 @"main_fn"()
{
entry:
entry.cond:
  %".2" = load double, double* %".5"
  %".3" = fcmp ogt double %".2",              0x0
  %".4" = uitofp i1 %".3" to double
  %".5" = fptosi double %".4" to i1
  br i1 %".5", label %"entry.if", label %"entry.endif"
entry.if:
  %".7" = load double, double* %".3"
  %".8" = call i32 (i64*, ...) @"printf"(i64* %".2", double %".7")
  %".9" = load double, double* %".3"

  store double %".10", double* %".3"
