* For PR950:Reid Spencer2006-11-271-2/+26
| | | | | | | | | | | 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
* For PR950:Reid Spencer2006-11-081-4/+2
| | | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31542 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | Replace the REM instruction with UREM, SREM and FREM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31369 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-10-261-1/+3
| | | | | | | | | Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31195 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-10-201-109/+39
| | | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31063 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | Remove exception throwing/handling from lib/Bytecode, and adjust its users to compensate for changes in the interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29875 91177308-0d34-0410-b5e6-96231b3b80d8

The default is "true" to retain the same behavior as previously provided by this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28562 91177308-0d34-0410-b5e6-96231b3b80d8

* Adjust the interface to ConstantArray::get. The previousReid Spencer2006-05-301-1/+1
| | | | | | | | | | implementation always added a null byte to the end of the string. It turns out that this is not always wanted. By adding a length parameter we preserve this behavior when length==0 (default value) but also allow other lengths (not null terminated) to be created. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28552 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | Minor tweaks in public headers and a few .cpp files so that LLVM can build successfully with -pedantic and projects using LLVM with -pedantic don't get warnings from LLVM. There's still more -pedantic warnings to fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28453 91177308-0d34-0410-b5e6-96231b3b80d8

* Split SimpleConstantVal up into its components, so each Constant subclass getsChris Lattner2005-09-271-22/+16
| | | | | | | | | | | | a different enum value. This allows 'classof' for these to be really simple, not needing to call getType() anymore. This speeds up isa/dyncast/etc for constants, and also makes them smaller. For example, the text section of a release build of InstCombine.cpp shrinks from 230037 bytes to 216363 bytes, a 6% reduction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23466 91177308-0d34-0410-b5e6-96231b3b80d8

* Eliminate the explicit opcode field in ConstantExpr, using the SubclassDataChris Lattner2005-02-051-13/+9
