Reid Spencer 8c3d3dce2b For PR1293:
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

Reid Spencer 4e42790c43 1. Make StoreValueToMemory a little more efficient by not requiring caller
to make a copy of the GenericValue.
2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were
   truncated to 32

Reid Spencer 1efc4aaf84 Fix some thinko's in the last patch. PtrSize has to be in bits and we
might need to zext not just trunc the value.

2007-03-06 03:46:41 +00:00
Reid Spencer 10dbc1e896 Fix a bug in IntToPtr. Truncating to 64-bits only works if the integer
is larger. Adjust so that it truncates to pointer width, only if necessary.

Reid Spencer c764c55745 Simplify code as a result of the change in GenericValue to have a single
integer field of type APInt instead of different sized integer fields.

2007-03-06 03:11:31 +00:00
Reid Spencer 40015aad5a Radically simplify execution. This patch gets rid of all the special
handling for integer of various sizes. GenericValue now has just a single
integer field of type APInt. We use its facilities directly in the
execution of all instructions.

llvm-svn: 34951
2007-03-06 03:09:31 +00:00
Reid Spencer c45e10474a Adjust and simplify external function processing now that GenericValue has
a single integer field of type APInt.

2007-03-06 03:08:12 +00:00
Reid Spencer 7f68713eb8 APInt's are no longer allocated on the heap because they are direct
members of GenericValue. Consequently the code to clean them up isn't
needed.

2007-03-06 03:06:48 +00:00
Reid Spencer 2d89fa84bc Remove the insufficient code in Interpreter::create that computed the
Target DataLayout incorrectly. For now, we'll trust that the module has
got the correct DataLayout. In the future, this needs to be changed to
tell the TargetData to be "current host".

llvm-svn: 34947
2007-03-06 03:05:57 +00:00
Reid Spencer 87aa65f40e Simplify things significantly because GenericValue now has a single integer
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.

Reid Spencer 54c6e84c83 Implement APInt support for the binary operators.
Move the getConstantExpr function towards the end of the file so we don't
need a dozen forward declarations.

2007-03-03 06:22:22 +00:00
Reid Spencer 72aafa1d49 1. Have the ExecutionContext keep track of the APInt's allocated and
ensure they are cleaned up when the stack frame exits.
2. Move a function to the Execution.cpp file where it belongs.

Chris Lattner 4da5e17cfc From Dan Gohman:
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

Reid Spencer 2341c22ec7 Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

Chris Lattner 7476fa4456 DOUT still evaluates side effects, even though it doesn't print. This means
that disassembleBuffer will be called even if NDEBUG, but the result will
be ignored.

2007-01-20 20:51:43 +00:00
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 a94d394ad2 For PR1043:
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Reid Spencer 726b68bc6e Fix a regression in the last patch. When constructing a BitMask, be careful
not to overflow 64-bits and end up with a 0 mask. This caused i64 values to
always be stored as 0 with lots of consequential damage to nightly test.

Reid Spencer fab44b682e Two changes:
1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are

2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.
