Dominance properties don't hold in unreachable code

Chris Lattner f75832b015 * Verify function prototypes, not just functions with bodies. 
* Verify that functions do not take aggregates as arguments.

Reid Spencer 4148139dd9 Fix for bug 348. 
The SymbolTable changes caused this one too.

Brian Gaeke e8a6bf3d21 Fold two assertions with backwards error messages into one with a 
correct error message.

John Criswell 987ad1945d Fixed inconsistent indentation.

Chris Lattner 0377e4384f Make sure to check for a very bad class of errors: an instruction 
that does not dominate all of its users, but is in the same basic block as
its users.  This class of error is what caused the mysterious CBE only
failures last night.

John Criswell c4e72c9a0a Remove the return type check for llvm.readio. This check is done for all 
functions and is not needed here.
Simplify the pointer type check per Chris's suggestions.

llvm-svn: 12945
 2004-04-14 15:06:48 +00:00
John Criswell 0c654c6a4e Added code to verify that llvm.readio's pointer argument returns something 
that matches its return type.

llvm-svn: 12944
 2004-04-14 14:49:36 +00:00
John Criswell 23c48d63d6 Finish adding the llvm.readio and llvm.writeio intrinsics. 
Sorry these didn't get in yesterday.

llvm-svn: 12942
 2004-04-14 13:46:52 +00:00
John Criswell 2b4c96e758 Reversed the order of the llvm.writeport() operands so that the value 
is listed first and the address is listed second.

llvm-svn: 12795
 2004-04-09 19:09:14 +00:00
John Criswell 5201004ef9 Added the llvm.readport and llvm.writeport intrinsics. 
The Verifier ensures that their parameters are of integral types and have
the correct sign, but it does not enforce any size restrictions because
such restrictions are platform dependent.

Chris Lattner a45a216ff6 Make the verifier API more complete and useful.

 2004-03-29 00:29:36 +00:00
Chris Lattner 9ece94b02b Catch some more cases of broken code. The loop extractor seems to be creating 
situations where there is a branch that goes to a block in another function.

Chris Lattner b870ca7766 verifyFunction has been broken for a long time now. Fix it.

Chris Lattner 071a5e5649 Rename the intrinsic enum values for llvm.va_* from Intrinsic::va_* to 
Intrinsic::va*.  This avoid conflicting with macros in the stdlib.h file.

Chris Lattner ec5089a223 Tighten up verifier checks. The result of an invoke instruction only 
dominates the normal destination, not the exceptional dest (ie, the result
of a call is undefined on an exception)

Chris Lattner df9779c5c2 Be more careful handling PHI nodes, which might be of potentially high degree. 
This reduces the time to verify a function from eon with a large number of
large PHI nodes from 22996s (6.38 hours) to 10.5499s

llvm-svn: 8411
 2003-09-08 19:44:26 +00:00
Chris Lattner ea9891311a As it turns out, things will be simpler than I first expected. We no longer 
need any exception handling intrinsics beyond llvm.unwind. (yaay)

llvm-svn: 8145
 2003-08-25 22:35:01 +00:00
Chris Lattner 7da3571af9 rethrow is really the language independent primitive here. "throw" can be written 
in terms of it and llvm.exc.setcurrent.

Rework the intrinsics.
