[PATCH] D131341: [RISC-V][HWASAN] Add tag mismatch routines for HWASAN required for RISC-V

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added inline comments.


================
Comment at: compiler-rt/lib/hwasan/hwasan_setjmp_riscv64.S:77
+  // no rv64if or lp64f
+#if (__riscv_flen == 32) || defined(__riscv_float_abi_single)
+# error "Unsupported case"
----------------
FLEN is irrelevant, only the floating-point ABI matters. This also doesn't fail for lp64q. What you want is:

* __riscv_float_abi_soft - do nothing
* __riscv_float_abi_double - save/restore
* anything else - error
