NAME

6       llvm-readelf - GNU-style LLVM Object Reader
7

SYNOPSIS

9       llvm-readelf [options] [input...]
10

DESCRIPTION

12       The  llvm-readelf  tool  displays low-level format-specific information
13       about one or more object files.
14
15       If input is "-", llvm-readelf reads from standard input. Otherwise,  it
16       will read from the specified filenames.
17

OPTIONS

19       --all, -a
20              Equivalent  to  specifying all the main display options relevant
21              to the file format.

25
26       --arch-specific, -A
27              Display architecture-specific  information,  e.g.  the  ARM  at‐
28              tributes section on ARM.
29
30       --bb-addr-map
31              Display  the contents of the basic block address map section(s),
32              which contain the address of each function, along with the rela‐
33              tive offset of each basic block.
34

46
47       --dynamic-table, --dynamic, -d
48              Display the dynamic table.
49

171              Read command-line options from response file <FILE>.
172
