2010-02-11Add and commonize encoder support for all immediates.Chris Lattner
Stub out some dummy fixups to make things work. We can now emit fixups like this: subl $20, %esp ## encoding: [0x83,0xec,A] ## fixup A - offset: 2, value: 20, kind: fixup_1byte_imm Emitting $20 as a single-byte fixup to be later resolved by the assembler is ridiculous of course (vs just emitting the byte) but this is a failure of the matcher, which should be producing an imm of 20, not an MCExpr of 20. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95860 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-10The previous fix of widening divides that trap was too fragile as it depends ↵Mon P Wang
on custom lowering and requires that certain types exist in ValueTypes.h. Modified widening to check if an op can trap and if so, the widening algorithm will apply only the op on the defined elements. It is safer to do this in widening because the optimizer can't guarantee removing unused ops in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95823 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09Radar 7417921Jim Grosbach
tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to register instruction only works with low registers. Allowing high registers for the instruction resulted in the assembler choosing the wide (32-bit) encoding for the mov, but LLVM though the instruction was only 16 bits wide, so offset calculations for constant pools became incorrect, leading to out of range constant pool entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95686 91177308-0d34-0410-b5e6-96231b3b80d8
