CVS commit: src/usr.bin/make

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Mon Jan  1 21:47:33 UTC 2007

Modified Files:
        src/usr.bin/make: parse.c

Log Message:
Rework the code that separates the makefile into lines.
Instead of copying the file byte by byte into an expanding line buffer, just
scan the file buffer for (unescaped) newlines.
Escaped newlines (etc) are processed by modifying the file buffer later.
Speeds up 'nbmake obj' by a factor of 2.
I suspect it will do wonders for parts of pkgsrc as well, since it largely
eliminates cpu cycles from the false part of .ifs.
