| * | riscv: Add support for XTheadBb in string-fz[a,i].h | Christoph Müllner | 2023-09-06 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | XTheadBb has similar instructions like Zbb, which allow optimized string processing: * th.ff0: find-first zero is a CLZ instruction. * th.tstnbz: Similar like orc.b, but with a bit-inverted result. The instructions are documented here: https://github.com/T-head-Semi/thead-extension-spec/tree/master/xtheadbb These instructions can be found in the T-Head C906 and the C910. Tested with the string tests. Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> | ||||
| * | riscv: Add string-fza.h and string-fzi.h | Adhemerval Zanella | 2023-02-06 | 1 | -0/+77 |
| It uses the bitmanip extension to optimize index_fist and index_last with clz/ctz (using generic implementation that routes to compiler builtin) and orc.b to check null bytes. Checked the string test on riscv64 user mode. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> | |||||
