[PATCH] D125875: [RISCV] Add vread_csr and vwrite_csr to riscv_vector.h

[Craig Topper via Phabricator via cfe-commits]

craig.topper added inline comments.


================
Comment at: clang/include/clang/Basic/riscv_vector.td:1511
+__extension__ extern __inline
+__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
+unsigned long vread_csr(enum RVV_CSR csr) {
----------------
Do we need __gnu_inline__ and __artificial__? The only intrinsics headers that have them in clang are in ppc_wrappers. X86 uses `__attribute__((__always_inline__, __nodebug__`


================
Comment at: clang/include/clang/Basic/riscv_vector.td:1512
+__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
+unsigned long vread_csr(enum RVV_CSR csr) {
+  unsigned long rv = 0;
----------------
X86 and arm_neon.h uses double underscore prefixes on all variables in intrinsic headers to reduce the chance of a collision with a user having a macro with the same name.
