[PATCH] D110869: [X86] Implement -fzero-call-used-regs option

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/X86/X86RegisterInfo.td:647
+def GeneralPurposeRegisters : RegisterCategory<[GR64, GR32, GR16, GR8]>;
+def FixedRegisters : RegisterCategory<[DEBUG_REG, CONTROL_REG, CCR, FPCCR,
+                                       DFCCR, TILE, VK1PAIR, VK2PAIR, VK4PAIR,
----------------
Should we still have this comment from the non-tablegen implementation "The following may not be "fixed" registers, but we don't want them anyway." applied to the VK*PAIRS and TILE?
