2007-02-06Two fixes:Chris Lattner
1. Memset takes an i32 for the value to set, not i8. This was causing GCC to ICE all over the place (PR1183). 2. memcpy/memmove were not properly zext/trunc'ing the size in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33970 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-02Changes to support making the shift instructions be true BinaryOperators.Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33776 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-29Use TargetData to obtain the correct size of the "size_t" argument forReid Spencer
functions like memcpy, memmove and memset. Ensure only one prototype is used for these functions and that it matches the system definition by using the appropriate type for the size argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33618 91177308-0d34-0410-b5e6-96231b3b80d8

Force memcpy to be the 32-bit variant. Since this is only used with CBE and lli which both target 32-bit machines, this should be okay. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33608 91177308-0d34-0410-b5e6-96231b3b80d8
2007-01-15rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger.Chris Lattner
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! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33225 91177308-0d34-0410-b5e6-96231b3b80d8

2006-12-31For PR950:Reid Spencer
Three changes: 1. Convert signed integer types to signless versions. 2. Implement the @sext and @zext parameter attributes. Previously the type of an function parameter was used to determine whether it should be sign extended or zero extended before the call. This information is now communicated via the function type's parameter attributes. 3. The interface to LowerCallTo had to be changed in order to accommodate the parameter attribute information. Although it would have been convenient to pass in the FunctionType itself, there isn't always one present in the caller. Consequently, a signedness indication for the result type and for each parameter was provided for in the interface to this method. All implementations were changed to make the adjustment necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32788 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-27For PR950:Reid Spencer
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8

2006-01-16For PR411:Reid Spencer
This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25366 91177308-0d34-0410-b5e6-96231b3b80d8

2005-10-23When a function takes a variable number of pointer arguments, with a zeroJeff Cohen
pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23888 91177308-0d34-0410-b5e6-96231b3b80d8
