           Summary: 'nofp', 'nosimd', 'nocrypto' and 'nofp16' feature
                    modifiers for Aarch64 fail to build
           Product: gcc
           Version: 8.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Patch unrolling wrapped lines in config/aarch64/aarch64-option-extensions.def

Build of GCC 8.2.0 fails when built with --with-arch=armv8-a+nocrypto

AARCH64_OPT_EXTENSION for 'fp', 'simd', 'crypto' and 'fp16' in
config/aarch64/aarch64-option-extensions.def file are wrapped around. They are
consumed by config.gcc@3739 and expected to be a single lines. When these lines
are wrapped around config.gcc produces invalid tm.h file and gcc fails to build
consequently.
