Subject: Convert skip_altivec_tests to allow form
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c2b7bed6454a1253564715f7985a6abac5eb4cdc;p=binutils-gdb.git

Convert skip_altivec_tests to allow form

This renames skip_altivec_tests to allow_altivec_tests and updates its
users to use require.
