varasm.c (default_exception_section): Move to...
* varasm.c (default_exception_section): Move to...
* except.c (default_exception_section): ... here. Make
.gcc_except_table read-only if it is not expected to have any
dynamic relocations and linker handles it.
* dwarf2out.c (default_eh_frame_section): Make .eh_frame read-only
if it is not expected to have any dynamic relocations and linker
handles it.
* configure.in (HAVE_LD_RO_RW_SECTION_MIXING): Check what ld does
when linking read-only and read-write sections together.
* configure, config.in: Rebuilt.
* crtstuff.c (EH_FRAME_SECTION_CONST): Define.
(__EH_FRAME_BEGIN__, __FRAME_END__): Add it.
