Subject: [musl] getauxval availability
Date: Sun, 16 Feb 2020 08:43:54 -0500	[thread overview]
Message-ID: <CAH8yC8=i5P7WcGDR8f2_kaypjaDX9nZSowmPaKY4vV+7_MpckQ@mail.gmail.com> (raw)

Hi Everyone,

We use getauxval on Linux when available to determine cpu caps. For
Glibc the code looks like (http://lwn.net/Articles/519085/):

#if (((__GLIBC__ * 100) + __GLIBC_MINOR__) >= 216)
# define GETAUXV_AVAILABLE 1
#endif

I need a similar test for musl. It looks like the function was added
at https://git.musl-libc.org/cgit/musl/commit/?id=21ada94c4b8c. I
don't see how to map a commit to a release for the web front-end musl
uses.

The release page indicates it should be available with musl-1.0.1,
which was released April 16 2014
(https://www.musl-libc.org/releases/). But I am not sure about the
musl release process, and what is included in a release tarball.

What is the first release of musl that contains 21ada94c4b8c ?

Jeff
