Summary: Emission of XRay table was occasionally disabled for Arm32, but this bug was not then detected because earlier (also by mistake) testing of XRay was occasionally disabled on 32-bit Arm targets. This patch should fix that problem and detect such problems in the future. This patch is one of a series, see also - https://reviews.llvm.org/D28623 Reviewers: rengolin, dberris Reviewed By: dberris Subscribers: llvm-commits, aemerson, rengolin, dberris, iid_iunknown Differential Revision: https://reviews.llvm.org/D28624 llvm-svn: 292516
