From: Junio C Hamano Date: Thu, 20 Jul 2017 23:29:59 +0000 (-0700) Subject: Merge branch 'jk/build-with-asan' X-Git-Tag: v2.14.0-rc1~10 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/e4efb39555582c5687df7a585f4cd9043dcd8ebc?ds=inline;hp=-c Merge branch 'jk/build-with-asan' A recent update made it easier to use "-fsanitize=" option while compiling but supported only one sanitize option. Allow more than one to be combined, joined with a comma, like "make SANITIZE=foo,bar". * jk/build-with-asan: Makefile: allow combining UBSan with other sanitizers --- e4efb39555582c5687df7a585f4cd9043dcd8ebc diff --combined Makefile index ba4359ef8d,d3ba23fdd2..9b98535a04 --- a/Makefile +++ b/Makefile @@@ -19,34 -19,16 +19,34 @@@ all: # have been written to the final string if enough space had been available. # # Define FREAD_READS_DIRECTORIES if you are on a system which succeeds -# when attempting to read from an fopen'ed directory. +# when attempting to read from an fopen'ed directory (or even to fopen +# it at all). # # Define NO_OPENSSL environment variable if you do not have OpenSSL. # This also implies BLK_SHA1. # -# Define USE_LIBPCRE if you have and want to use libpcre. git-grep will be -# able to use Perl-compatible regular expressions. -# -# Define LIBPCREDIR=/foo/bar if your libpcre header and library files are in -# /foo/bar/include and /foo/bar/lib directories. +# Define USE_LIBPCRE if you have and want to use libpcre.
