From d62fe83005cae1c370570a5e49b902d81648958b Mon Sep 17 00:00:00 2001 From: Matt Arsenault Date: Thu, 20 Jul 2017 00:37:31 +0000 Subject: Replace -print-whole-regmask with a threshold. The previous flag/default of printing everything is not helpful when there are thousands of registers in the mask. llvm-svn: 308572 --- llvm/lib/CodeGen/MachineInstr.cpp | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) (limited to 'llvm/lib/CodeGen/MachineInstr.cpp') diff --git a/llvm/lib/CodeGen/MachineInstr.cpp b/llvm/lib/CodeGen/MachineInstr.cpp index afea5575a3a..017352abb32 100644 --- a/llvm/lib/CodeGen/MachineInstr.cpp +++ b/llvm/lib/CodeGen/MachineInstr.cpp @@ -73,10 +73,12 @@ using namespace llvm; -static cl::opt PrintWholeRegMask( - "print-whole-regmask", - cl::desc("Print the full contents of regmask operands in IR dumps"), - cl::init(true), cl::Hidden); +static cl::opt PrintRegMaskNumRegs( + "print-regmask-num-regs", + cl::desc("Number of registers to limit to when " + "printing regmask operands in IR dumps.
