Any line that starts with '#@' marker carries auxiliary data in form of a |
|
key-value pair, for example: |
|
|
|
#@ tool: * |
|
#@ board: unix |
|
|
|
So far tool and board parameters are recognized. Their value can contain |
|
arbitrary glob expression. Based on aforementioned parameters given manifest |
|
will be applied for all test results, but only in selected test runs. Note |
|
that all parameters are optional. Their default value is '*' (i.e. for all |
|
tools/boards). |
|
|
|
The meaning of lines above is as follows: corresponding test results to follow |
|
should only be suppressed if test run was performed on "unix" board. |
|
|
|
The summary line used to build the test result should have this format: |
|
|
|
attrlist | UNRESOLVED: gcc.dg/unroll_1.c (test for excess errors) |
|
^^^^^^^^ ^^^^^^^^^^ ^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^ |
