This series introduces initial flags and functionality for the fp8 feature.
Specifically, the following are added: - functions that enable constructing valid fpm register values. - support for the '+fp8' -march modifier. - support for reading and writing the new system register FPMR (Floating Point Mode Register) which configures the new FP8 features Tested against aarch64-unknown-linux-gnu. V1 of this patch series had "aarch64: Add march flags for +fp8 arch extensions" as cover letter title. Since then, changes in V2 are: aarch64: Add march flags for +fp8 arch extensions - Removed __ARM_FEATURE_FP8 define: will be added once the relevant features are in. - Some unnecessary whitespace changes were removed. - Helper function names now begin with __arm. aarch64: Add support for moving fpm system register - Removed a misleading comment. - Removed unnecessary modifier in .md aarch64: Add fpm register helper functions. - Helper functions and fpm_t types are available unconditionally when including arm_acle.h Is this ok for master? I do not have merge permissions. Can someone merge this for me please?
