[GR-36478] Unable to determine size of debuginfo on Darwin

[fniephaus]

It looks like we did not look into Darwin as part of #4082. e.getName().contains(".debug") doesn't seem to do anything on macOS, so the new build output is unable to report the size of debuginfo.

Could you please look into this, @zakkak? Thanks!

My guess would be that on Darwin ".debug" would instead be "__debug".

[olpaw]

I infer that fix from

$ objdump --all-headers hellojava | grep debug
 28 .debug_aranges 0002b8a0  0000000000000000  0000000000000000  00ae3d28  2**3
 29 .debug_info   000e624a  0000000000000000  0000000000000000  00b0f5c8  2**3

on linux vs.

> objdump -all-headers hello.dSYM/Contents/Resources/DWARF/hello | grep debug
  7 __debug_line  0000004a 0000000100003000 DATA

 13 __debug_str   0000005b 000000010000317d DATA

on darwin.

That's true. Since we don't generate debug info for macOS (yet!?) I didn't look it up.

Could you please look into this, @zakkak? Thanks!

It looks like @olpaw beat me to it :)
I'll prepare a patch for it tomorrow.

I opened #4241 with a possible fix for this.
