Subject: [PATCH 26] i64: fix missing exp2f, log2f and powf symbols in
libm.a [BZ #23822]
When new symbol versions were introduced without SVID compatible
error handling the exp2f, log2f and powf symbols were accidentally
removed from the ia64 lim.a. The regression was introduced by
the commits
f5f0f5265162fe6f4f238abcd3086985f7c38d6d
New expf and exp2f version without SVID compat wrapper
72d3d281080be9f674982067d72874fd6cdb4b64
New symbol version for logf, log2f and powf without SVID compat
With WEAK_LIBM_ENTRY(foo), there is a hidden __foo and weak foo
symbol definition in both SHARED and !SHARED build.
[BZ #23822]
* sysdeps/ia64/fpu/e_exp2f.S (exp2f): Use WEAK_LIBM_ENTRY.
* sysdeps/ia64/fpu/e_log2f.S (log2f): Likewise.
* sysdeps/ia64/fpu/e_exp2f.S (powf): Likewise.
(cherry picked from commit ba5b14c7613980dfefcad6b6e88f913e5f596c59)
