| llvm-readelf - GNU-style LLVM Object Reader |
| =========================================== |
| |
| .. program:: llvm-readelf |
| |
| SYNOPSIS |
| -------- |
| |
| :program:`llvm-readelf` [*options*] [*input...*] |
| |
| DESCRIPTION |
| ----------- |
| |
| The :program:`llvm-readelf` tool displays low-level format-specific information |
| about one or more object files. |
| |
| If ``input`` is "``-``", :program:`llvm-readelf` reads from standard |
| input. Otherwise, it will read from the specified ``filenames``. |
| |
