* When promoting the result of fp_to_uint/fp_to_sint,Duncan Sands2008-11-101-10/+1
| | | | | | | | | | | | | | | | | | | inform the optimizers that the result must be zero/ sign extended from the smaller type. For example, if a fp to unsigned i16 is promoted to fp to i32, then we are allowed to assume that the extra 16 bits are zero (because the result of fp to i16 is undefined if the result does not fit in an i16). This is quite aggressive, but should help the optimizers produce better code. This requires correcting a test which thought that fp_to_uint is some kind of truncation, which it is not: in the testcase (which does fp to i1), either the fp value converts to 0 or 1 or the result is undefined, which is quite different to truncation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58991 91177308-0d34-0410-b5e6-96231b3b80d8

* Change how extended types are represented in MVTs. Instead of fiddlingDan Gohman2008-11-031-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | bits, use a union of a SimpleValueType enum and a regular Type*. This increases the size of MVT on 64-bit hosts from 32 bits to 64 bits. In most cases, this doesn't add significant overhead. There are places in codegen that use arrays of MVTs, so these are now larger, but they're small in common cases. This eliminates restrictions on the size of integer types and vector types that can be represented in codegen. As the included testcase demonstrates, it's now possible to codegen very large add operations. There are still some complications with using very large types. PR2880 is still open so they can't be used as return values on normal targets, there are no libcalls defined for very large integers so operations like multiply and divide aren't supported. This also introduces a minimal tablgen Type library, capable of handling IntegerType and VectorType. This will allow parts of TableGen that don't depend on using SimpleValueType values to handle arbitrary integer and vector types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58623 91177308-0d34-0410-b5e6-96231b3b80d8
