NAME
       llvm-size - print size information

SYNOPSIS
       llvm-size [options] [input...]

DESCRIPTION
       llvm-size  is a tool that prints	size information for binary files.  It
       is intended to be a drop-in replacement for GNU's size.

       The tool	prints size information	for each input specified. If no	 input
       is  specified, the program prints size information for a.out. If	"-" is
       specified as an input file, llvm-size reads a file  from	 the  standard
       input  stream. If an input is an	archive, size information will be dis-
       played for all its members.

OPTIONS
       -A     Equivalent to --format with a value of sysv.

       --arch=<arch>
	      Architecture(s) from Mach-O universal binaries to	display	infor-
	      mation for.

       -B     Equivalent to --format with a value of berkeley.

       --common
	      Include  ELF common symbol sizes in bss size for berkeley	output
	      format, or as a separate section entry for sysv output.  If  not
	      specified, these symbols are ignored.

       -d     Equivalent to --radix with a value of 10.

       -l     Display  verbose address and offset information for segments and
	      sections in Mach-O files in darwin format.

       --format=<format>
	      Set the output format to the <format> specified. Available <for-
	      mat> options are berkeley	(the default), sysv and	darwin.

	      Berkeley	output	summarises  text,  data	 and bss sizes in each
	      file, as shown below for a typical pair of ELF files:

		 $ llvm-size --format=berkeley test.o test2.o
		    text    data     bss     dec     hex filename
		     182      16       5     203      cb test.elf
		      82       8       1      91      5b test2.o

	      For Mach-O files,	the output format is slightly different:

		 $ llvm-size --format=berkeley macho.obj macho2.obj
		 __TEXT	 __DATA	 __OBJC	 others	 dec	 hex
		 4	 8	 0	 0	 12	 c	 macho.obj
		 16	 32	 0	 0	 48	 30	 macho2.obj

	      Sysv output displays size	and address information	for most  sec-
	      tions, with each file being listed separately:

		 $ llvm-size --format=sysv test.elf test2.o
		    test.elf  :
		    section	  size	    addr
		    .eh_frame	    92	 2097496
		    .text	    90	 2101248
		    .data	    16	 2105344
		    .bss	     5	 2105360
		    .comment	   209	       0
		    Total	   412

		    test2.o  :
		    section		size   addr
		    .text		  26	  0
		    .data		   8	  0
		    .bss		   1	  0
		    .comment		 106	  0
		    .note.GNU-stack	   0	  0
		    .eh_frame		  56	  0
		    .llvm_addrsig	   2	  0
		    Total		 199

	      darwin  format only affects Mach-O input files. If an input of a
	      different	file format is	specified,  llvm-size  falls  back  to
	      berkeley format. When producing darwin format, the tool displays
	      information about	segments and sections:

		 $ llvm-size --format=darwin macho.obj macho2.obj
		    macho.obj:
		    Segment : 12
			    Section (__TEXT, __text): 4
			    Section (__DATA, __data): 8
			    total 12
		    total 12
		    macho2.obj:
		    Segment : 48
			    Section (__TEXT, __text): 16
			    Section (__DATA, __data): 32
			    total 48
		    total 48

       --help, -h
	      Display a	summary	of command line	options.

       --help-list
	      Display an uncategorized summary of command line options.

       -m     Equivalent to --format with a value of darwin.

       -o     Equivalent to --radix with a value of 8.

       --radix=<value>
	      Display size information in the specified	radix. Permitted  val-
	      ues  are 8, 10 (the default) and 16 for octal, decimal and hexa-
	      decimal output respectively.

	      Example:

		 $ llvm-size --radix=8 test.o
		    text    data     bss     oct     hex filename
		    0152      04      04     162      72 test.o

		 $ llvm-size --radix=10	test.o
		    text    data     bss     dec     hex filename
		     106       4       4     114      72 test.o

		 $ llvm-size --radix=16	test.o
		    text    data     bss     dec     hex filename
		    0x6a     0x4     0x4     114      72 test.o

       --totals, -t
	      Applies only to berkeley output format. Display the  totals  for
	      all listed fields, in addition to	the individual file listings.

	      Example:

		 $ llvm-size --totals test.elf test2.o
		    text    data     bss     dec     hex filename
		     182      16       5     203      cb test.elf
		      82       8       1      91      5b test2.o
		     264      24       6     294     126 (TOTALS)

       --version
	      Display the version of the llvm-size executable.

       -x     Equivalent to --radix with a value of 16.

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

EXIT STATUS
       llvm-size exits with a non-zero exit code if there is an	error.	Other-
       wise, it	exits with code	0.
