[llvm-commits] Function aliases

[Anton Korobeynikov]

Chris,

> Ok, does this also apply to functions with bodies?
No. Declarations only. AsmParser takes care of this.

:) This was my initial proposal (some week ago), you've responded
something like "this will be waste of space and memory, since only few
functions will use this feature".

> Ok, they should be fixed! :)
Ok.

> void foo() alias bar {}
This isn't allowed. foo acts as bar's mirror, so body of foo is
redefinition.

> Do the two functions (the extern of bar and the decl of foo) get

They won't be linked. External functions can still call foo();
