* IR, X86: Understand !absolute_symbol metadata on global variables.Peter Collingbourne2016-12-081-0/+27
Summary: Attaching !absolute_symbol to a global variable does two things: 1) Marks it as an absolute symbol reference. 2) Specifies the value range of that symbol's address. Teach the X86 backend to allow absolute symbols to appear in place of immediates by extending the relocImm and mov64imm32 matchers. Start using relocImm in more places where it is legal. As previously proposed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2016-October/105800.html Differential Revision: https://reviews.llvm.org/D25878 llvm-svn: 289087
