Subject: Define write_profiling functions only in profile library [BZ #31756]
X-Git-Tag: glibc-2.40~177
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=6d3b523eb54198d15af6e042054912cf9f5210de;p=glibc.git

Define write_profiling functions only in profile library [BZ #31756]

libc.so doesn't use nor export write_profiling functions.  There is no
point to define them in libc.so nor in libc.a.  Fix BZ #31756 by defining
them only in profile library.

    This would normally mean it should be removed to get the same API
    in static libraries.  But since profiling is special in static libs
