|
|

955 |
|
|
|
956 |
CheckBc.pm - A module that runs some simple tests to see if one component source tree is backwards compatible another.
|
|
|
957 |
|
|
|
958 |
=head1 SYNOPSIS
|
|
|
959 |
|
|
|
960 |
my $checkBc = CheckBc->New('\branch1\comp\group', '\branch2\comp\group', 0);
|

=head1 DESCRIPTION
|
|
|
966 |
|
|
|
967 |
C<CheckBc> does the following checks to see if a backwards compatibility breaking change has been introduced:

=item 1
|
|
|
972 |
|
|
|
973 |
Compares the ARM F<.def> files to ensure that only new lines have been added to the end of the file.
|
|
|
974 |
|
|
|
975 |
=item 2
|
|
|
976 |
|
|
|
977 |
Compares the sizes of any classes that have an exported C++ constructor. This is done by compiling some generated C++ code that uses the C<sizeof> operator to print the relevant class sizes to C<STDOUT>. Compilation is done using the MSVC++ compiler.
|
|
|
978 |
|
|
|
979 |
=item 3
|
|
|
980 |
|
|
|
981 |
Compares the v-table layouts of any classes that have an exported C++ constructor. This is done by compiling each source code set to ARM4 assembler listings, comparing the v-table sections.

|

|

|
|
|
991 |
The component's headers must compile using Microsoft's Visual C++ compiler.
|
|
|
992 |
|
|
|
993 |
=item 2
|
|
|
994 |
|
|
|
995 |
The component's exported headers must compile when they are all #include'd into a single F<.cpp> file. If this is not the case, then additional headers and include paths can be passed into the constructor.
