Some benchmarks like those that need locales to be generated cannot be built and are hence skipped for cross builds. Tested by cross building for aarch64 on x86_64 and then running the generated benchmark on aarch64. * benchtests/Makefile (wcsmbs-benchset): Include only for native builds and runs. (LOCALES): Likewise. (bench-build): Build timing-type here instead of the bench target. Generate locale only for native builds. * benchtests/README: Add note for cross-building. --- ChangeLog | 7 +++++++ benchtests/Makefile | 23 +++++++++++++++++++---- benchtests/README | 4 +++- 3 files changed, 29 insertions(+), 5 deletions(-) diff --git a/ChangeLog b/ChangeLog index f26f8f8..ded1093 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,12 @@ 2016-04-20 Siddhesh Poyarekar + * benchtests/Makefile (wcsmbs-benchset): Include only for + native builds and runs. + (LOCALES): Likewise. + (bench-build): Build timing-type here instead of the bench + target.
