[PATCH] D159536: [BOLT] Implement '--assume-abi' option for AArch64

[Vladislav Khmelevsky via Phabricator via llvm-commits]

yota9 added inline comments.


================
Comment at: bolt/lib/Target/AArch64/AArch64MCPlusBuilder.cpp:447
+  void getCalleeSavedRegs(BitVector &Regs) const override {
+    Regs |= getAliases(AArch64::X19);
+    Regs |= getAliases(AArch64::X20);
----------------
I believe we must add X18 register also, since the ARM ABI says it might be platform-specific, so BOLT must preserve it's value
