The IBM Bounty Source page has a list of resources: https://www.bountysource.com/teams/ibm/bounties Travis also has ppc64le support, so if you add the linux-ppc64le target then FLAC will be tested on ppc64le.

Thank you for this collection of patches. How can I test them? What platforms (computers) have the ppc64 or POWER9 processor?

[flac-dev] [PATCH 0/7] PowerPC64 performance improvements
The following series adds initial vector support for PowerPC64. On POWER9, flac --best is about 3.3x faster. Amitay Isaacs (2): Add m4 macro to check for C __attribute__ features Check if compiler supports target attribute on ppc64 Anton Blanchard (5): configure.ac: Remove SPE detection code configure.ac: Add VSX enable/disable configure.ac: Fix FLAC__CPU_PPC on little endian, and add FLAC__CPU_PPC64 Add runtime detection of POWER8 and POWER9 Add VSX optimised versions of autocorrelation loops configure.ac | 53 +- m4/c_attribute.m4 | 18 + src/libFLAC/Makefile.am | 1 + src/libFLAC/cpu.c | 31 + src/libFLAC/include/private/cpu.h | 6 + src/libFLAC/include/private/lpc.h | 14 + src/libFLAC/lpc_intrin_vsx.c | 942 ++ src/libFLAC/stream_encoder.c | 30 + 8 files changed, 1086 insertions(+), 9 deletions(-) create mode 100644 m4/c_attribute.m4 create mode 100644 src/libFLAC/lpc_intrin_vsx.c -- 2.17.1 ___ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
