Subject: Fix alpha sqrt fegetenv namespace (bug 20768) [committed]
Date: Fri, 04 Nov 2016 17:20:00 -0000 [thread overview]
Message-ID: <alpine.DEB.2.20.1611041719350.25235@digraph.polyomino.org.uk> (raw)
On alpha, sqrt (a C90 function) brings in references to fegetenv
(C99), resulting in linknamespace test failures:
[initial] __sqrt -> [libm.a(w_sqrt.o)] __ieee754_sqrt ->
[libm.a(e_sqrt.o)] __feholdexcept -> [libm.a(feholdexcpt.o)] fegetenv
This patch fixes this by making __feholdexcept call __fegetenv instead
of fegetenv.
Tested for Alpha (compilation only). Committed.
