[PATCH] D146463: [CodeGen][RISCV] Change Shadow Call Stack Register to S11

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVFrameLowering.cpp:58
 
   const auto *RVFI = MF.getInfo<RISCVMachineFunctionInfo>();
   if (RVFI->useSaveRestoreLibCalls(MF)) {
----------------
Can you add a FIXME here? Using x27 should hopefully remove this restriction


================
Comment at: llvm/lib/TargetParser/RISCVTargetParser.cpp:105
+bool isX27ReservedByDefault(const Triple &TT) {
   // X18 is reserved for the ShadowCallStack ABI (even when not enabled).
   return TT.isOSFuchsia() || TT.isAndroid();
----------------
X18->X27
