From de76d1cc94c5a59000fbca9d5e53a5917f4e3041 Mon Sep 17 00:00:00 2001 From: Patrick Ohly Date: Wed, 12 Apr 2017 17:44:25 +0200 Subject: yocto-compat-layer: test signature differences when setting MACHINE Selecting a machine is only allowed to affect the signature of tasks that are specific to that machine. In other words, when MACHINE=A and MACHINE=B share a recipe foo and the output of foo, then both machine configurations must build foo in exactly the same way. Otherwise it is not possible to use both machines in the same distribution. This criteria can only be tested by testing different machines in combination, i.e. one main layer, potentially several additional BSP layers and an explicit choice of machines: yocto-compat-layer --additional-layers .../meta-intel --machines intel-corei7-64 imx6slevk -- .../meta-freescale To simplify the analysis and limit the amount of output, mismatches are sorted by task order such that tasks that run first are also reported first. Following tasks for the same recipe and set of machines then get pruned, because they are likely to be different because of the underlying task (same approach as in test_signatures). The difference here is that we get information about all machines. The task order in the base configuration serves as heuristic for sorting that merged list. The test has already found issues in go-cross (depended on tune-specific libgcc) and gdb-cross (had a tune-specific path unnecessarily), so it is also useful to uncover issues that are not caused by the BSP layer itself.
