[PATCH v3] RISC-V: Add split pattern to generate SFB instructions. [PR113095]
Since the match.pd transforms (zero_one == 0) ? y : z <op> y,
into ((typeof(y))zero_one * z) <op> y. Add splitters to recongize
this expression to generate SFB instructions.
gcc/ChangeLog:
PR target/113095
* config/riscv/sfb.md: New splitters to rewrite single bit
sign extension as the condition to SFB instructions.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sfb.c: New test.
* gcc.target/riscv/pr113095.c: New test.
