Hi Chris,

you are right, that file is autogenerated from the template file but both are kept under source control. The reason for this is that the autogenerated file is not created at build time but by manually running the tfm_parse_manifest_list.py, which has to be run every time something in the manifest is changed, and the resulting autogenerated file is committed under source control as well.

On the other hand, the build system could be modified to run the parsers at build time so that the autogenerated files wouldn't have to be stored in source control, and we could keep only the template. These two alternatives are both equally valid in my view, but if there is strong consensus for the other we can discuss.

Thanks, Antonio

Can somebody please help me understand this? $ ls platform/ext/common/armclang/ tfm_common_s.sct tfm_common_s.sct.template $ ls platform/ext/common/gcc tfm_common_s.ld tfm_common_s.ld.template In both directories, both files are under source control, but the non-template files say that they're auto-generated: /*********** WARNING: This is an auto-generated file. Do not edit! ***********/

It's unusual to see both the source file and the artifact under source control.

It seems that they're generated by tools/tfm_parse_manifest_list.py, but that doesn't seem to be run as part of the build, so when is it run?

Thanks,

Chris
