Remark utility

## NAME

llvm-remarkutil - Remark utility

## SYNOPSIS

**llvm-remarkutil** \[*subcommmand*\] \[*options*\]

## DESCRIPTION

Utility for displaying information from, and converting between different *remark* formats.

## SUBCOMMANDS

- •

  *bitstream2yaml* - Reserialize bitstream remarks to YAML.

- •

  *yaml2bitstream* - Reserialize YAML remarks to bitstream.

- •

  *instruction-count* - Output function instruction counts.

### bitstream2yaml

USAGE: **llvm-remarkutil** bitstream2yaml \<input file\> -o \<output file\>

### Summary

Takes a bitstream remark file as input, and reserializes that file as YAML.

### yaml2bitstream

USAGE: **llvm-remarkutil** yaml2bitstream \<input file\> -o \<output file\>

### Summary

Takes a YAML remark file as input, and reserializes that file in the bitstream format.

### instruction-count

USAGE: **llvm-remarkutil** instruction-count \<input file\> –parser=\<bitstream\|yaml\> -o \<output file\>

### Summary

Outputs instruction count remarks for every function. Instruction count remarks encode the number of instructions in a function at assembly printing time.

Instruction count remarks require asm-printer remarks.

CSV format is as follows:

- **::**

  Function,InstructionCount foo,123
