Summary: spec does not mention that inline asm is a valid
"return" statement.
Product: D
Version: 1.043
Platform: All
OS/Version: All
Status: NEW
Keywords: spec
Severity: normal
Priority: P2

The spec on return mentions that:
"At least one return statement, throw statement, or assert(0) expression is
required if the function specifies a return type that is not void. "
However, in the inline asm docs the following example is there:
int foo(int x)
{
asm
{
mov EAX,x[EBP] ; // loads value of parameter x into EAX
mov EAX,x ; // does the same thing
}
}
And DMD indeed allows inline asm to specify the return value, we've even had to
take the time to emulate this undocumented behaviour in LDC. It should be in
the spec, or there should be an assert(0) inserted after the inline asm!
