4 Using cross-file analysis
Cadvise provides different operating modes for performing cross-file analysis of the application.
The cross-file analysis can be performed along with the regular build of the application, or separated
from the regular build. You can also initiate it either on all the files or only on a selected group of
files or modules. It can also be disabled completely. The default and recommended mode is to
enable cross-file analysis at link time. Cadvise fetches all the recorded information from the PDB
for all the object files specified at the link command line and performs cross-file analysis.
Usage:
-crossfile = option
Table 3 Cross-file analysis options
DescriptionOption
Disables cross-file analysis. If a PDB location is specified using the –pdb
option, the logs of errors and the diagnostic messages found during the
compile time of the application are stored in the PDB.
none
Directs the cross-file analysis to be automatically done at the link time of
the application. This is the default mode.
auto
Does not initiate the cross-file analysis at the link time of the application.
When you use this option, a PDB location must be specified using the –pdb
defer
option. During the compile time of the application, logs and intermediate
representation files are stored in the PDB so that the cross-file analysis can
be initiated later with either of the
–crossfile=[pdb|module|list|listfile] options.
Initiates cross-file analysis on all the intermediate representation files stored
in the PDB. When you use this option, a PDB location must be specified
using the –pdb option.
pdb
Enables cross-file analysis of object files in a PDB corresponding to a
particular module(shared library or executable). During the build, cadvise
module:<module_name>
records the list of files that make up the module. So, for cross-file analysis,you
can use the name of the module instead of specifying the list of object files.
Enables cross-file analysis of object files in a PDB corresponding to the listed
object files. File1, File2,..., FileN are object files. For more information, see
.
list:<file1:file2:.. ..:fileN>
Enables cross-file analysis of object files in a PDB corresponding to the
object files listed in the specified file. The list of object files in <file_name>
listfile:<file_name>
must be separated by space or newline characters. For more information,
see Example 15 (page 24).
The following examples illustrate the equivalent usage of different cross-file options to perform
cross-file analysis:
