Subject: [PATCH] scripts: Translate profile2linkerlist.
Date: Sun, 07 Aug 2016 12:33:26 -0600	[thread overview]
Message-ID: <57A77EF6.5030200@gmail.com> (raw)


profile2linkerlist.pl is a script that takes the sorted output of the 
readprofile command and turns it into a list of C functions in a 
format for linker lists. Make the script more portable across POSIX 
systems. This script does not use any shell-specific features, only 
POSIX ones. A POSIX shell is present on all UNIX systems, while Perl 
is not as commonplace.
