From 72062f5744557e270a38192554c3126ea5f97434 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174054 91177308-0d34-0410-b5e6-96231b3b80d8 --- projects/sample/autoconf/config.sub | 4 +++- projects/sample/autoconf/configure.ac | 6 +++++- projects/sample/configure | 9 +++++++-- 3 files changed, 15 insertions(+), 4 deletions(-) (limited to 'projects') diff --git a/projects/sample/autoconf/config.sub b/projects/sample/autoconf/config.sub index 9942491..9d22c1e 100755 --- a/projects/sample/autoconf/config.sub +++ b/projects/sample/autoconf/config.sub @@ -251,7 +251,8 @@ case $basic_machine in | alpha64 | alpha64ev[4-8] | alpha64ev56 | alpha64ev6[78] | alpha64pca5[67] \ | am33_2.0 \ | arc | arm | arm[bl]e | arme[lb] | armv[2345] | armv[345][lb] | avr | avr32 \ - | be32 | be64 \ + | be32 | be64 \ + | aarch64 \ | bfin \ | c4x | clipper \ | d10v | d30v | dlx | dsp16xx \ @@ -359,6 +360,7 @@ case $basic_machine in | alpha64-* | alpha64ev[4-8]-* | alpha64ev56-* | alpha64ev6[78]-* \ | alphapca5[67]-* | alpha64pca5[67]-* | arc-* \ | arm-* | armbe-* | armle-* | armeb-* | armv*-* \ + | aarch64-* \ | avr-* | avr32-* \ | be32-* | be64-* \ | bfin-* | bs2000-* \ diff --git a/projects/sample/autoconf/configure.ac b/projects/sample/autoconf/configure.ac index 1763ea2..283bc12 100644 --- a/projects/sample/autoconf/configure.ac +++ b/projects/sample/autoconf/configure.ac @@ -304,6 +304,7 @@ AC_CACHE_CHECK([target architecture],[llvm_cv_target_arch], sparc*-*) llvm_cv_target_arch="Sparc" ;;
