-------- Original Message -------- Subject: ppl 0.11.2 vs llvm Date: Tue, 2 Aug 2011 11:19:11 -0400 From: Jack Howarth howarth@bromo.med.uc.edu To: bagnara@cs.unipr.it
Roberto, Have you done any build of ppl 0.11.2 against the llvm-gcc or clang compilers? Mac OS X 10.7 (Lion) defaults to llvm-gcc and the fink project has switch to clang for their 10.7 builds. Both llvm based compilers produce a ppl 0.11.2 build which fails a subset of tests. For example the second build of affineimage1 in Box fails with...
[MacPro:build/tests/Box] root# ./affineimage1 tests failed: test08
The problem occurs with both llvm-gcc-4.2 and clang3.0svn from Xcode 4.1 as well as current clang svn. We should try to find out if this is a bug in ppl or in the llvm backend of the llvm-gcc and clang compilers. Thanks in advance for any help in pinning this down. Jack ps The problem isn't system related since the Xcode gcc-4.2 compiler still produces a ppl build with no testsuite regressions. Apple will be depeciating the gcc-4.2 compiler out of Xcode in favor of llvm-gcc-4.2 at some point so we do need to address these ppl failures under llvm-based compilers.
