Brian Gaeke 7b4be13f94 Represent va_list in interpreter as a (ec-stack-depth . var-arg-index) 
pair, and look up varargs in the execution stack every time, instead of
just pushing iterators (which can be invalidated during callFunction())
around.  (union GenericValue now has a "pair of uints" member, to support
this mechanism.) Fixes Bug 234.

Brian Gaeke 242ebf2523 Fix off-by-one in Interpreter::getFirstVarArg(), which was punishing 
any attempts by LLI to use varargs (possibly left over from the introduction
of IntrinsicLowering??)

Brian Gaeke 51f100753c The Interpreter was failing the AtExit UnitTest. This fixes it.

Brian Gaeke 1c0133ffd9 Don't pass anything to the IntrinsicLowering class that is not_intrinsic, 
because that makes it abort. Also, fix a typo in a comment.

This checkin brought to you by the "It only takes about 30 seconds to run
ENABLE_LLI tests on Shootout on zion, even if they all dump core" fund.

Chris Lattner 5d236005b0 Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering 
implementation from the TargetMachine directly.

 2003-12-28 21:23:38 +00:00
Chris Lattner c8c6c03dda Pass around IntrinsicLowering instances as appropriate. 
Reimplement the Interpreters implementation of va_* to be more direct.

Brian Gaeke 13a2e54e0c Dynamically get the right-sized member of a GenericValue to hold a size_t, and 
use it to return the result of strlen.

 2003-12-12 15:38:06 +00:00
Brian Gaeke 8657acc07e Since we are using a gep_type_iterator, we apparently must get the type 
index by using I.getOperand() here. This was failing an assertion on
basically every struct access.

llvm-svn: 10426
 2003-12-12 05:13:05 +00:00
Brian Gaeke 2bba152fb8 Fix typo in comment. Add prototype for getConstantExprValue(). 
llvm-svn: 10390
 2003-12-11 00:23:28 +00:00
Brian Gaeke 5a8ec7d5f6 Add support for --debug-only=interpreter, to print out instrs before 
interpreting them.

Move support for getting the value of a ConstantExpr into
getConstantExprValue(), and add support for the rest of the different
kinds of ConstantExprs.  (I don't think I like ConstantExprs!)
This requires separate procedures executeShlInst() and executeShrInst().

Reduce the number of references to TheEE.

Get rid of an old comment mentioning annotations.

Fix exitCalled(), which was crashing the Interpreter. This was a
leftover from the return-value code refactoring.

Brian Gaeke d81ca471dd Change LLI's internal representation of va_list to a pointer to the next 
argument to be returned by va_arg. This allows va_lists to be passed
between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)

llvm-svn: 9965
 2003-11-13 06:06:01 +00:00
Brian Gaeke 960707c335 Put all LLVM code into the llvm namespace, as per bug 109.

Brian Gaeke 9ef636c698 Implement vaarg instruction. This is not quite perfect: 2003-08-11-VaListArg 
still causes a crash. But it's better than before.

Brian Gaeke 85baf8c65a popStackAndReturnValueToCaller() must advance instruction pointer to normal 
destination, if returning from an invoke.

Implement 'unwind' instruction.

Brian Gaeke a6454d3532 visitCallInst --> visitCallSite. 
Use visitCallSite to implement both CallInsts and InvokeInsts.

llvm-svn: 9788
 2003-11-07 20:04:22 +00:00
Brian Gaeke a6d48e4db2 Make the operation of visitCallInst() only depend on the CallSite. 
llvm-svn: 9787
 2003-11-07 19:59:08 +00:00
Brian Gaeke 18b59578c9 Use CallSites for call sites, instead of CallInsts. A revolutionary concept.

 2003-11-07 19:26:23 +00:00
Brian Gaeke 65cac90a92 Refactor the return-from-function code into popStackAndReturnValueToCaller(). 
Make external function calls slightly less special; now they get a stack frame.
