2005-01-19Implement Regression/CodeGen/X86/rotate.ll: emit rotate instructions (whichChris Lattner
typically cost 1 cycle) instead of shld/shrd instruction (which are typically 6 or more cycles). This also saves code space. For example, instead of emitting: rotr: mov %EAX, DWORD PTR [%ESP + 4] mov %CL, BYTE PTR [%ESP + 8] shrd %EAX, %EAX, %CL ret rotli: mov %EAX, DWORD PTR [%ESP + 4] shrd %EAX, %EAX, 27 ret Emit: rotr32: mov %CL, BYTE PTR [%ESP + 8] mov %EAX, DWORD PTR [%ESP + 4] ror %EAX, %CL ret rotli32: mov %EAX, DWORD PTR [%ESP + 4] ror %EAX, 27 ret We also emit byte rotate instructions which do not have a sh[lr]d counterpart at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19692 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-19Teach the code generator that shrd/shld is commutable if it has an immediate.Chris Lattner
This allows us to generate this: foo: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] shld %EDX, %EDX, 2 shl %EAX, 2 ret instead of this: foo: mov %EAX, DWORD PTR [%ESP + 4] mov %ECX, DWORD PTR [%ESP + 8] mov %EDX, %EAX shrd %EDX, %ECX, 30 shl %EAX, 2 ret Note the magically transmogrifying immediate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19686 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-19Implement a way of expanding shifts. This applies to targets that offerChris Lattner
select operations or to shifts that are by a constant. This automatically implements (with no special code) all of the special cases for shift by 32, shift by < 32 and shift by > 32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19679 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-19Add a hook to find out how the target handles shift amounts that are out ofChris Lattner
range. Either they are undefined (the default), they mask the shift amount to the size of the register (X86, Alpha, etc), or they extend the shift (PPC). This defaults to undefined, which is conservatively correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19677 91177308-0d34-0410-b5e6-96231b3b80d8
