From e0e3aefdd3affa427693ce6434599af38fcb7a13 Mon Sep 17 00:00:00 2001 From: Tim Northover Date: Thu, 31 Jan 2013 12:12:40 +0000 Subject: Add AArch64 as an experimental target. This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054 --- llvm/configure | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'llvm/configure') diff --git a/llvm/configure b/llvm/configure index 73326a773d5..9e74ab61b60 100755 --- a/llvm/configure +++ b/llvm/configure @@ -1438,8 +1438,8 @@ Optional Features: YES) --enable-targets Build specific host targets: all or target1,target2,...
