Reid Spencer fff2797349 Implement the signed icmp instructions properly. To do this we introduce
a small inline function to sign extend a uint64_t value based on its
type's bitwidth. This function is then used in both executeSExtInst and
the various executeICMP_S** functions.

Reid Spencer 300e7fcb55 Make shl instruction mask its result to the correct bitsize. This is
sufficient to get llvm-test/SingleSource/UnitTests/Integer/general-test.ll
working with lli in interpreter mode.

Reid Spencer fab44b682e Two changes:
1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are
   acceptable as indices.
2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.

Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

Chris Lattner c69c6c4db2 eliminate calls to Type::isInteger, preferring isIntegral instead.

Reid Spencer 7a9c62baa6 For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

Reid Spencer 6c38f0bb07 For PR950:
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

Jeff Cohen 2439669c6f The interpreter assumes that the caller of runFunction() must be lli, and
therefore the function being called must be a main() returning an int.  The
consequences when these assumptions are false are not good, so don't assume
them.

Brian Gaeke ad373c8576 Go back to the interpreter main loop after performing intrinsic lowering,
because 1) the first instruction might not be a call site, and
2) CS and SF.Caller were not getting set to point to the new call site
anyway (resulting in a crash on e.g. call %llvm.memset).

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 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 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.)
