Feature flag handling was not perfect, +nofp16 disabled fp instructions too. New feature flag macros were added to check features with multiple bits set (matters for FP_F16 and SIMD_F16 opcode feature tests). The unused AARCH64_OPCODE_HAS_FEATURE was removed, all checks should use one of the AARCH64_CPU_HAS_* macros. AARCH64_CPU_HAS_FEATURE now checks all feature bits. The aarch64_features table now contains the dependencies as a separate field (so when the feature is enabled all dependencies are enabled and when it is disabled everything that depends on it is disabled). Note that armv8-a+foo+nofoo is not equivalent to armv8-a if +foo turns on dependent features that nofoo does not turn off. gas/ * config/tc-aarch64.c (struct aarch64_option_cpu_value_table): Add require field. (aarch64_features): Initialize require fields. (aarch64_parse_features): Handle dependencies. (aarch64_feature_enable_set, aarch64_feature_disable_set): New. (md_assemble): Use AARCH64_CPU_HAS_ALL_FEATURES. * testsuite/gas/aarch64/illegal-nofp16.s: New. * testsuite/gas/aarch64/illegal-nofp16.l: New. * testsuite/gas/aarch64/illegal-nofp16.d: New. include/ * opcode/aarch64.h (AARCH64_CPU_HAS_ALL_FEATURES): New. (AARCH64_CPU_HAS_ANY_FEATURES): New. (AARCH64_CPU_HAS_FEATURE): Define as AARCH64_CPU_HAS_ALL_FEATURES. (AARCH64_OPCODE_HAS_FEATURE): Remove. |
