Since gcc commit,
3c70b3ca1ef58f302bf8c16d9e7c7bb8626408bf, we now enable
elf attributes for all riscv targets by default in gcc. Therefore, I
think binutils should have the same behavior, in case users are writing
assembly files. If --enable-default-riscv-attribute isn't set, then we
enable the elf attributes for all riscv targets by default.
ChangLog:
binutils/
* testsuite/binutils-all/readelf.s: Add comments for riscv.
* testsuite/binutils-all/readelf.s-64: Likewise.
* testsuite/binutils-all/readelf.s-64-unused: Likewise.
* testsuite/binutils-all/readelf.ss: Likewise.
* testsuite/binutils-all/readelf.ss-64: Likewise.
* testsuite/binutils-all/readelf.ss-64-unused: Likewise.
gas/
* configure.ac: If --enable-default-riscv-attribute isn't set,
then we enable the elf attributes for all riscv targets by
default.
* configure: Regenerated.
