Large lma delta using binutils 2.19

[James Blackburn]

Hi All,

I've been moving from binutils 2.17 to 2.19 and noticed an oddity in the final lma / vma address allocation.

In ld_lang.c#lang_size_sections_1(...) (line 4705 on HEAD) the lma is set to dot + (last.lma - last.vma). The result is that a subsequent section gets a very large lma.

Is this the intended behaviour? If so what's the recommended way of getting the linker to behave in the previous way and use the calculated vma(/dot) as the lma?

Many thanks,
James
