[flac-dev] issue with flac_internal_CreateFile_utf8

Hi guys, There is a missing return type in flac_internal_CreateFile_utf8 in case of #if _MSC_VER > 1900 && WINAPI_FAMILY_PARTITION(WINAPI_PARTITION_APP) I suppose there should ba a return handle; Thanks ! -- Olivier Tristan Research & Development www.uvi.net

Thank you for this collection of patches. How can I test them? What platforms (computers) have the ppc64 or POWER9 processor? Brian On Jul 10, 2018, at 2:31 PM, Anton Blanchard wrote: > > The following series adds initial vector support for PowerPC64. > On POWER9, flac --best is about 3.3x
