Subject: Fix build failure on tilepro due to unsupported atomics
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a546080d517c8833ce1d6abdb86a9293c8d29bae;p=thirdparty%2Fglibc.git

Fix build failure on tilepro due to unsupported atomics

        * malloc/malloc.c (malloc_state): Use int for have_fastchunks since
        not all targets support atomics on bool.

(cherry-picked from 2c2245b92ccf6344b324d17d8f94ccd3b8c559c6)
