From af1e278b91cdf2ebb76c18b0b0302b42186dee67 Mon Sep 17 00:00:00 2001 From: Daniel Sanders Date: Sun, 15 Oct 2017 18:22:54 +0000 Subject: [PATCH] Re-commit r315863: [globalisel][tablegen] Import ComplexPattern when used as an operator Summary: It's possible for a ComplexPattern to be used as an operator in a match pattern. This is used by the load/store patterns in AArch64 to name the suboperands returned by ComplexPattern predicate so that they can be broken apart and referenced independently in the result pattern. This patch adds support for this in order to enable the import of load/store patterns. Depends on D37445 Hopefully fixed the ambiguous constructor that a large number of bots reported.
