[SelectionDAG][X86][ARM] Teach ExpandIntRes_ABS to use sra+add+xor expansion when ADDCARRY is supported. (details)
[SCCP] Compute ranges for supported intrinsics (details)

Commit da79b1eecc65171f6ca0cda9b4f1970bd1503c17 by craig.topper [SelectionDAG][X86][ARM] Teach ExpandIntRes_ABS to use sra+add+xor expansion when ADDCARRY is supported. Rather than using SELECT instructions, use SRA, UADDO/ADDCARRY and XORs to expand ABS. This is the multi-part version of the sequence we use in LegalizeDAG. It's also the same as the Custom sequence uses for i64 on 32-bit and i128 on 64-bit. So we can remove the X86 customization.

Commit 9fb46a452d4e5666828c95610ceac8dcd9e4ce16 by nikita.ppv [SCCP] Compute ranges for supported intrinsics For intrinsics supported by ConstantRange, compute the result range based on the argument ranges. We do this independently of whether some or all of the input ranges are full, as we can often still constrain the result in some way. Differential Revision: https://reviews.llvm.org/D87183
