[PATCH] D32657: Change the format of the map file.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu created this revision.

Previously, we printed out input sections and input files in
separate columns as shown below.

  Address          Size             Align Out     In      File    Symbol
  0000000000201000 0000000000000015     4 .text
  0000000000201000 000000000000000e     4         .text
  0000000000201000 000000000000000e     4                 foo.o
  0000000000201000 0000000000000000     0                         _start
  0000000000201005 0000000000000000     0                         f(int)
  000000000020100e 0000000000000000     0                         local
  0000000000201010 0000000000000002     4                 bar.o
  0000000000201010 0000000000000000     0                         foo
  0000000000201011 0000000000000000     0                         bar

This format doesn't make much sense because for each input section,
there's always exactly one input file. This patch changes the format
to this.

  Address          Size             Align Out     In      Symbol
  0000000000201000 0000000000000015     4 .text
  0000000000201000 000000000000000e     4         foo.o:(.text)
  0000000000201000 0000000000000000     0                 _start
  0000000000201005 0000000000000000     0                 f(int)
  000000000020100e 0000000000000000     0                 local
  0000000000201010 0000000000000002     4         bar.o:(.text)
  0000000000201010 0000000000000000     0                 foo
  0000000000201011 0000000000000000     0                 bar
