[AArch64][GlobalISel] Enable GlobalISel at -O0 by default Tests updated to explicitly use fast-isel at -O0 instead of implicitly. This change also allows an explicit -fast-isel option to override an implicitly enabled global-isel. Otherwise -fast-isel would have no effect at -O0. Differential Revision: https://reviews.llvm.org/D41362 llvm-svn: 321655

Fix erroneous flag in GISel line for arm64-fast-isel-materialize.ll Accidentally put a fast-isel-abort=2 instead of the GISel abort line. This test doesn't actually fall back at all for GISel though, so remove the fallback checks entirely. llvm-svn: 359737

[GlobalISel][AArch64] Use fmov for G_FCONSTANT when possible This adds support for using fmov rather than a standard mov to materialize G_FCONSTANT when it's safe to do so. Update arm64-fast-isel-materialize.ll and select-constant.mir to show that the selection is correct. llvm-svn: 359734

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090
