Better testing infrastructure for remote targets will be an absolutely fantastic improvement. Thank you and Dan both for pushing forward on the topic. +1 I remember Greg (cc'd) did some of that in

...t; In compiler-rt, I'd configure such a build with the following CMake variables: I'm not sure we're on the same page... Your example, and the way that lit is currently set up, assumes BUILD and HOST are the same machine. > LLVM_LIT=$BUILD/lit > CMAKE_C_COMPILER=$HOST/clang > COMPILER_RT_EMULATOR=$TARGET/qemu Let me give a concrete example: BUILD=i686-pc-linux-gnu HOST=i386-pc-win32 TARGET=arm-elf (on say, real hardware, or i686-pc-linux/bin/qemu-system-arm, or i386-pc-win32/bin/qemu-system-arm) Here I'd like to run lit on the linux machine such that test compilation happens on...

...default blacklist tests. I had to move those into the clang test suite. As for cross-compilation and test ARM Linux, I needed to update all tests to include '%sim' before invoking cross-compiled executables. For x86, the variable is empty. For cross-compiling, it's a user-configured ${COMPILER_RT_EMULATOR}, which for ARM Linux, is QEMU. There are currently a handful of test failures. If you'd like, I can XFAIL them and commit this stuff sooner than later. Do you want these patches? -Greg On Fri, Apr 4, 2014 at 10:22 AM, Greg Fitzgerald <garious at gmail.com> wrote: >>>&g...
