2014-04-04Document optional comma in linker script.Cary Coutant1-2/+7
The linker script documentation does not mention the optional comma that may follow an output section command or an overlay command. In some cases, where a fill expression is used, and the next output section command begins with an operator (e.g., "/DISCARD/"), the comma may be required to separate the two commands. Currently, GNU ld doesn't require the comma, but gold does. ld/ PR gold/16804 * ld.texinfo: Document optional comma following output section command and overlay command.

2014-01-22Make assignments to dot keep an empty output section.Alan Modra1-4/+9
An assignment to dot in an output section that allocates space of course keeps the output section. Here, I'm changing the behaviour for assignments that don't allocate space. The idea is not so much to allow people to force output of an empty section with ". = .", but to fix cases where an otherwise empty section has padding added by an alignment expression that changes with relaxation or .eh_frame editing. Such a section might have zero size before relaxation and so be stripped incorrectly. ld/ * ld.texinfo (Output Section Discarding): Mention assigning to dot as a way of keeping otherwise empty sections. * ldexp.c (is_dot, is_value, is_sym_value, is_dot_ne_0, is_dot_plus_0, is_align_conditional): New predicates.
