[X86] Replace slow LEA instructions in X86 According to Intel's Optimization Reference Manual for SNB+: " For LEA instructions with three source operands and some specific situations, instruction latency has increased to 3 cycles, and must dispatch via port 1: - LEA that has all three source operands: base, index, and offset - LEA that uses base and index registers where the base is EBP, RBP,or R13 - LEA that uses RIP relative addressing mode - LEA that uses 16-bit addressing mode " This patch currently handles the first 2 cases only.

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

[X86] Replace slow LEA instructions in X86 According to Intel's Optimization Reference Manual for SNB+: " For LEA instructions with three source operands and some specific situations, instruction latency has increased to 3 cycles, and must dispatch via port 1: - LEA that has all three source operands: base, index, and offset - LEA that uses base and index registers where the base is EBP, RBP,or R13 - LEA that uses RIP relative addressing mode - LEA that uses 16-bit addressing mode " This patch currently handles the first 2 cases only.
