Subject: ARM: Default to apcs-gnu ABI for NetBSD
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=454c2087b9422c4f45864cab7b535cd4daec1195;p=clang

ARM: Default to apcs-gnu ABI for NetBSD

r216662 changed the default ABI for 32-bit ARM targets to be "aapcs"
when no environment is given in the triple, however NetBSD requires it
to be "apcs-gnu".
