Duncan Sands 85fab3a3ad Simplify caller updating using a CallSite, as 
requested by Chris.  While there, do the same
for an existing function committed by someone
called "lattner" :)

Owen Anderson a54570d2d2 I got the predicate backwards in my last patch. The comment is correct, the code was not. 
llvm-svn: 47264
 2008-02-18 09:22:21 +00:00
Owen Anderson c66655e14c Duncan pointed out that we can fast fail here, because the sret parameter of 
a function must be the first parameter.

Owen Anderson c64dfb4317 Add a predicate to Argument to check for the StructRet attribute.

Chris Lattner 536ddedea3 targets that support quotes for mangled names still need to escape newlines 
when they occur in the name, just like " is escaped.

 2008-02-15 18:54:56 +00:00
Chris Lattner 7f5c2553c7 check that terminators only occur at the end of a block. This catches the 
common problem of putting two terminators in the same block.  I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

Duncan Sands 92a56b5499 It turns out that in C++ it is legal to declare functions 
that return an opaque type by value, as long as you don't
call it or provide a body (you can take the address of it).
So it is wrong to insist that sret parameters not be an
opaque*.  And I guess it is really up to codegen to complain
if someone tries to call such a function.  I'm also removing
the analogous check from byval parameters, since I don't
see why we shouldn't allow them as long as no-one tries to
call the function or give it a body.

llvm-svn: 46216
 2008-01-21 21:37:41 +00:00
Duncan Sands 262e54eb7b Check that sret is only used on pointers to types 
with a size, like byval.

Duncan Sands a59f396cba Be consistent with other attribute methods, and 
check the callee also if it is known.
