New Revision: 313999
URL: https://svnweb.freebsd.org/changeset/base/313999
Log:
Consolidate statements to initialize files.
Previously, the first lines of various generated files from system call
tables were generated in two sections. Some of the initialization was
done in BEGIN, and the rest was done when the first line was encountered.
The main reason for this split before r313564 was that most of the
initialization done in the second section depended on the $FreeBSD$ tag
extracted from the system call table. Now that the $FreeBSD$ tag is no
longer used, consolidate all of the file initialization in the BEGIN
section.
This change was tested by confirming that the content of generated files
did not change.
