From 52a25237d894fd5736a90f11df2c5c9391d13fd5 Mon Sep 17 00:00:00 2001 From: Tobias Grosser Date: Wed, 4 Feb 2015 20:55:43 +0000 Subject: Import isl(+imath) as an external library into Polly With this patch Polly is always GPL-free (no dependency on GMP any more). As a result, building and distributing Polly will be easier. Furthermore, there is no need to tightly coordinate isl and Polly releases anymore. We import isl b3e0fa7a05d as well as imath 4d707e5ef2. These are the git versions Polly currently was tested with when using utils/checkout_isl.sh. The imported libraries are both MIT-style licensed. We build isl and imath with -fvisibility=hidden to avoid clashes in case other projects (such as gcc) use conflicting versions of isl. The use of imath can temporarily reduce compile-time performance of Polly. We will work on performance tuning in tree. Patches to isl should be contributed first to the main isl repository and can then later be reimported to Polly. This patch is also a prerequisite for the upcoming isl C++ interface. llvm-svn: 228193 --- polly/lib/External/isl/test_inputs/codegen/unroll7.in | 5 +++++ 1 file changed, 5 insertions(+) create mode 100644 polly/lib/External/isl/test_inputs/codegen/unroll7.in (limited to 'polly/lib/External/isl/test_inputs/codegen/unroll7.in') diff --git a/polly/lib/External/isl/test_inputs/codegen/unroll7.in b/polly/lib/External/isl/test_inputs/codegen/unroll7.in new file mode 100644 index 00000000000..494e5975564 --- /dev/null +++ b/polly/lib/External/isl/test_inputs/codegen/unroll7.in @@ -0,0 +1,5 @@ +# Check that some code is generated. +# Older versions of isl would abort on unknown divs. +{ S[i,j] -> [i,j]: exists (alpha, beta: j=i+4alpha +3beta and 0 <= alpha < 24 and 0 <= beta and 0 <= i,j < 5) } +{ : } +{ [i,j] -> unroll[x] } -- cgit v1.2.1
