[llvm-commits] [PATCH] emit DW_AT_high_pc into CUs

[shinichiro hamaji]

Hi,

I've filed a bug and submitted a patch in bugzilla one week ago but I found
one-off patches are supposed to be submitted in this list. So, let me post
my patch. I confirmed my patch still works against r160611 and all test
passes on linux and mac.

With this patch, LLVM emits DW_ AT_high_pc into a CU if the CU has
functions only in .text. The DW_AT_high_pc helps tools to skip CUs which
don't have an address they are looking for. Actually, this patch
significantly improves the speed of addr2line in GNU binutils. See the bug
for detail.

Could someone review my patch?

Thanks!
