[PATCH] D74205: [WIP][llvm-dwarfdump] Add the --show-sections-sizes option

[Djordje Todorovic via Phabricator via llvm-commits]

djtodoro added a comment.

I found it useful when testing some large patches, since the `llvm-size` does not calculate it, I usually do it manually or by some scripting.

An example of the output:

  llvm-dwarfdump --show-sections-sizes test.o
  ----------------------------------------------------
  test.o: file format ELF64-x86-64
  ----------------------------------------------------
    SECTION 			  SIZE
  ------------ 		  -----------------------
   .debug_info 		  132  (19.67%)
   .debug_str 		  178  (26.53%)
   .debug_abbrev 		  120  (17.88%)
   .debug_line 		  74  (11.03%)
   .debug_ranges 		  0  (0.00%)
   .debug_loc 		  89  (13.26%)
  
   .debug_*: 		  593  (88.38%)
  ----------------------------------------------------
   TOTAL FILE SIZE: 671
  ----------------------------------------------------
