Thanks, David Codesourcery (and therefore Mentor Graphics) certainly distribute (and sell) PowerPC ELF EABI gcc toolchains for 32-bit PowerPC devices. I don't know how many different types they use in testing, but I expect they have a number of systems. I'm sure they'd be interested in your changes.
32-bit PowerPC reference test platform
Hello, what is the reference test platform for the 32-bit PowerPC target? We have the primary target powerpc64-unknown-linux-gnu and the secondary target powerpc-ibm-aix5.3.0.0. On the GCC compile farm there is no AIX available http://gcc.gnu.org/wiki/CompileFarm and I don't have an AIX machine. On which platform should I test to show that changes like this http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02931.html cause no harm? -- Sebastian Huber, embedded brains GmbH Address : Obere Lagerstr. 30, D-82178 Puchheim, Germany Phone : +49 89 18 90 80 79-6 Fax : +49 89 18 90 80 79-9 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request.

On the GCC compile farm there is no AIX available http://gcc.gnu.org/wiki/CompileFarm First, I am trying to have IBM contribute an AIX system to the GCC Compile Farm. and I don't have an AIX machine. On which platform should I test to show that changes like this http://gcc.gnu.org/ml/gcc-patches/2012-10/msg02931.html cause no harm? I am not sure what you mean by 32 bit PowerPC target? Yes, AIX defaults to building 32 bit applications, but 32 bit PowerPC processors are quite different (both Freescale processors and other PPC32 targets). And AIX does not support ELF, sdata, sdata2, etc. that are referenced in many of those testcases. Thanks, David
